Keywords: Environmental protection, Grey relational analysis, Waste discharge, Environmental remediation, Resource utilization.
Abstract: This paper evaluates the environment protection level of 30 Provinces in China using grey relational analysis based on 10 indicators which can be divided into 3groups waste discharge, environmental remediation and resource utilization. Evaluation has been done on both integrated and separate according to 3 kinds of indicators. Result shows that the best provinces in environment protection are Zhejiang, Tianjin and Beijing while the worst provinces are Ningxia, Qinghai and Xinjiang. The level of environment protection in the eastern coastal areas is relatively higher, and the level of environmental protection in northwest region is relatively low. Provinces that have higher GDP per capita are likely to have higher environment protection, and vice versa. Most provinces are unbalanced in the3 aspects and few provinces managed a full range environment protection. Cities are found to be better in waste discharge and resource utilization while resource based provinces are on the contrary.

Keywords: Plantation forests, Algebraic difference approach, Dynamic update technique, Richards ' differential site, index model.
Abstract: Differential site index models were constructed using both algebraic difference approach (ADA) and the generalized algebraic difference approach (GADA) in this study to evaluate the site quality of forest land without the site index table. Data related to China fir (Cunninghamia lanceolata (Lamb). Hook) were selected to fit the diferential site index models and then the optimal model was chosen. The optimal model was determined using an accuracy test and residual analysis, and then the dynamic update technique of the optimal model was studied by MATLAB and NET. The results showed that Richards ' differential site index model (SI=19.171x (Ht/19.171)In(1-exp(0.067x20)in (1-exp (o.067 At))) had the best prediction performance. The ADA and GADA could be used to evaluate site quality without the site index table and the differential site index model could provide prompt dynamic updates.

Keywords: Molecular weight, Organic matter, Ganjiang river.
Abstract: Using the method of ultrafiltration, the raw water of Nanchang section of Ganjinang River and the water after conventional treatment were estimated to determine the molecular weight distribution. The results showed that the raw water of Ganjiang River has a molecular weight distribution with large edges and small middle parts, which meant that the organic matter mainly centralized in a scope where the molecules were larger than 30ku or less than 1ku, and the middle size matter occupied a relatively small proportion. In winter low-water season, there was little organic matter in the river and the small organic matter increased, whereas the small organic matter molecules decreased and the large organic matter molecules became dominant. The ordinary water purifying process of Nanchang city was just to remove the large molecules of the organic matter mainly, which led to an unsatisfying result where the small molecules were barely removed.

Abstract: Large-scale integration of wind power has brought profound challenge to traditional power generation dispatch. It becomes necessary to effectively coordinate the operation of wind power sources. Traditional economic dispatch to minimize the fuel cost no longer meets the need for environmental protection when emission reduction is mandatory. Based on the optimal dispatch in traditional power system, the concept of :energy-environmental efficiency ? was introduced to modify the optimal dispatch model in wind power integrated system, and the multi-objective optimal dispatch model was proposed on the basis of comprehensively considering the minimum of the resource consumption, the best energy-environmental efficiency and the highest system stability. A hybrid particle swarm and simulated annealing optimization algorithm with fuzzy technology was presented to solve the optimization model. Compared with traditional economic dispatch, the model proposed in this paper is reasonable and can be better protect the ecological environment.

Abstract: In this study, Cr (VI0 is removed from Wastewater using activated carbon derived from water hyacinth as an unconventional adsorbent. The aquatic plants commonly referred as aquatic weeds found in rivers, lakes and water logged areas pose a number of problems in water resource utilization. This work deals with one such weed ?water hyacinth? which was selected to prepare activated carbon. The physical and chemical characteristics of the activated carbon prepared were determined. The study determines the parameters that influence adsorption process such as Ph, initial metal ion concentration, contact time and adsorbent dosage. The suitability of Freundiich and Langmuir models was investigated for each chromium sorbent system. The Lagergren ' s constants were calculated for different initial concentrations of metal ions.

Abstract: A major proportion of discharge in the Juntanghu river basin is contributed by its glacier-fed river and snow catchments situated in northern mid-slope of Tianshan Mountain, Northwest China. The Mann-Kendall trend test based on the 50 yeas data (1961to 2011) were used for analysis of the climate change trends and the application of the SWAT model under different climate change scenarios show that watershed hydrological cycle would alter different climatic scenarios. This suggests that the reservoirs will be necessary for large flow storage to meet the need of the flood control, water supply, etc.

Abstract: We identified the major non-timber forest products (NT FPS) , their contributions to household incomes, and the determinants influencing engagement of households in using NTFPs in the Bonga forest area of Gimbo and Decha Districts of Kaffa Zone, southwest Ethiopia. Six Kebeles (the lowest administrative unit in Ethiopia) were sampled from two districts and 150 households were randomly sampled using proportion al- to-size techniques based on the number of farm households in each Kebele. Secondary data were collected from and focus group discussions were conducted with selected individuals . The farmers diversified livelihood activities such as crop and livestock production , collection of NTFPs and off-farm activities . NTFPs played a significant role in household incomes. The contribution from the major NTFPs (forest coffee, honey and spices ) accounted for 47% of annual household income. The role of NTFPs was influenced by a number of factors. Variables including being native to the area (+), total land holding (+) , possession of livestock (+) and access to extension (+) significantly affected forest coffee production . Age of household head (-), land holding(+)and distance of the market from the residence (-) significantly affected honey production. Size of landholding (+) , distance to market (-) and distance of the forest from the residence (-) were significant variables determining the NTFP incoes derived by the households.Attention is needed in the design of policies and strategies for thewell-being of households to the contribution of NTFPs to local incomes and the variables that affect the collection of NTFPs must be considered.

Abstract: Swat district is a biodiversity hub of Pakistan . The plant species, especially trees , in the swat District are exposed to extinction threat from global climate change. Maximum entropy (MaxEnt) modeling of species distribution , using HADCM3 A2a global climate change scenario , predicte a considerable change in the future distribution of Abies pindrow (Royle ex D. Don) Royle. AUC(area under the curve ) values of 0.972 and 0.983 were significant for the present and future distribution models of the species respectively. It is clear that bioclimatic variables such as the mean temperature of the warmest quarter (bio_10) and the annual temperature range (bio_7) contribute significantly to the model and thus affect the predicted distribution and density of the species .The future model predicts that by the year 2080 population density will have decreased significantly . The highest density of the species is recorded in the eastern and western borders of the valley in the areas of sulatanr and Mankial. The changes in density and distribution of the species can have considerable impact ,not only on the trees species itself, but on the associated subflora as well.

Abstract: We examined the local community incentive programs to improve traditional forest management in three forested villages in Baneh city, Kurdistan province in the northern Zagros forests of western Iran. Zagros forests cover 6.07 million ha and support rich plant and animal diversity. Changes in local community social and economic systems and the inefficiency of traditional forest management led to a critical situation in the stability of forest regeneration in recent decades. Due to a shortage of productive and arable lands and resulting unemploymentand poverty,people overexploited the Zagros forests. Outside intervention in traditional forest management organizations. To achieve sustainable forest management organizations. To achieve sustainable forest management organizations. To achieve sustainable forest management ,including forest resources conservation and improvement of natural resource based livelihoods of communities, it is desirable to implement Forestry Incentive programs(FIP) based on the important functions of forests. Detailed information on the socio-economics of communities though questionnaire, interview and observation . We studied 276 households in three villages and completed 76 questionnaires by householders in the quantitative analysis.sampling was performed by simple random sampling (SRS) . The needs of rural communities ,such as livestock husbandary ,mainly arise from the characteristics and environmental features of villages. We identified the driving forces , pressures , status , impacts and responses (DPSIR) to design incentive programs , by DPSIR analysis and interaction analysis. Evaluation of local community benefits from forests showed that in order to improve forest management , 319 dollars per year would be needed by each family as an incentive in 2010 to prevent lopping and firewood collecting, the main causes of forest degradation.

Abstract: Fungi are often used to induce agarwood in Aquilaria trees. This study was conducted to evaluate the effect of several fungi on agarwood formation over time in young Aquilaria malaccensis (Lam.) trees. Typical changes in the length and light intensity of the resulting discoloration were observed after three and six month periods following inoculation. Wood samples were observed microscopically and classified in to several light intensity groups. The discoloration length was measured longitudinally .The duration after inoculation affected the mean of discoloration length: the 6-month old sample (1.70 cm) had a wider discoloration zone when compared to the 3 -month old sample (1.17 cm). When measuring the discoloration intensity , a positive relationship with time was perceived. Digital images, captured using a camera -equipped microscope ,revealed that wood samples collected after six months appeared to be 1.8 times darker than after three months.We concluded that time ,not the species of any of the tested fungi, had significant effect on discoloration length and intensity .Gas chromatography /mass spectrometry(GCMS) analysis of the 6 -month old sample yielded some important agarwood compounds such as benzylacetone , anisylacetone, guaiene and palustrol .This demonstrates that the tested fungi have the ability to induce agarwood formation in nursery A. malaccensis trees.

Abstract: We measured erodibility and mean weight diameter (MWD)of soil aggregates in different parts of a forest road. Samples of topsoil were collected from cutslope, fillslope,road surface and forest ground to assess the texture ,bulk density , moisture,caco? and organic matter. Soil aggregate stability was determined by wet sieving .Soil erodibiity on the road surface was 2.3 and 1.3 times higher than on thefillslope and cutslope , respectively. The forest soil had the lowest erodibility .Aggregate stability of cutslope and road surface were low and very low, respectively. There was a significant negative relationship between cutslope erodibility with caco? and sand content. Cutslope erodibility increased with increasing silt,clay and moisture content. On fillslopes, MWD increased with increasing rock fragment cover, plant cover , litter cover, organic matter and sand. There was a strong negative correlation between fillslope erodibility and organic atter ,sand and MWD.There was no significant difference between erodibility of bare soil and soils beneath Rubus hyrcanus L.and Philonotis marchica(Hedw).

Abstract: Landscape structure is often regarded as an important factor that governs the distribution and abundance of species. Therefore it is critical to understand the landscapes and their dynamics .Patterns of landscape elements and their dynamics. Pattern s of landscape elements strongly influence the ecological characteristics . This study was designed to document and map the current status of the tropical dry deciduous forest of the Taboda -Andhari Tiger Reserve (TATR), Central India(using IRS P6 LISS IV data) and to describe its landscape structure at three levels of organization viz. landscape,class,and patch.The study area was classified into 10 land cover classes that include 6 vegetation classes. The landscape structure was analyzed using FRAGSTATS using 12 set of indices.The TATR landscape have a total of 2,307 patches with a mean patch size of 25.67 ha and patch density of 1.7 patches per km? .Amongst all land cover classes, mixed bamboo forest is dominant -it occupied maximu area (77.99%)- while riparian forest is least represented (0.32%). Mixed forest has maximum number of patches among all vegetation classes. Results have shown that despite being dominant in the area, mixed bamboo forest is attributed to large patch sizes and not to the number of patches.This study has focused on the approach of integrating satellite forest classification and forest inventory data for studying forest landscape patterns.

Abstract: Terminilia Bellerica Roxb.(Belleric myrobalan) is one of the important multipurpose trees in central India. The fruits of the tree are highly valued for medicinal uses,with the greatest dmand coming from the pharmaceutical industry.This has resulted in overexploitation and present harvesting practices have led to a significant decline in natural regeneration for this tree species. Our study was conducted from 2006 to 2009. In chattisgarh(India) to standardize suitable harvesting practices for sustainable management for this valuable species.Experiments were conducted at four different sites located in Dhamtari, Sarguja, and Raigarh forest divisions of the state ,covering both protected and open forest in a complete randomized block design(RCBD). At each site, linear transects of 200 m x 100 m (2 ha) were randomly selected to sample the initial population and study the effects of two harvesting methods (traditional and nondestructive)and four harvesting intensities (60%, 70%,80%,90%) on the sustainability of T. bellerica. Fruits were collected and analyzed for their tannin and gallic acid content.Significant increase in tannin and galic acid content. Significant increase in tannin and gallic acid content was found with the maturity of fruits (September to December). This is the first study to experimentally assess the consequences of harvesting intensity ,time, and method are key factors for maintaining the population.Nondestructive harvesting methods were found to be superior to traditional harvesting in terms of regeneration ,recruitment,and concentration of active ingredients.When the fruits were harvested through non-destructive means at maturity, the population of species increased .The study concludes that 70% harvest of T.bellerica fruits through non-destructive means maintains the sustainability and provides quality raw material for the pharmaceutical industry.
