According to the definition of wetland in Ramsar Convention on Wetlands, the wetlands of Shanghai were classified into 4 types: coastal, riverine, lacustrine, and reservoir and pond wetlands. In order to examine the roles of wetlands in the life-support system of Shanghai, we calculated the area of each type of the wetlands using GIS technique, and then measured the ecological service values of different ecosystems in Shanghai based on the classification of ecosystem services proposed by COSTANZA et al. (1997). The estimated annual value of ecosystem services in the study area was 7.3×109US$/a for the total area of 1 356 700ha, among which about 97% was provided by the wetlands. Effective conservation and management of wetlands are therefore crucial to Shanghai’s sustainable development. The limitations of the evaluation method for ecosystem service value were also discussed in the present paper.展开更多

Songnen plain, located in Northeast China, is one of the national key bases for agricultural production. Because there were remarkable variations in land use in recent years, it can supply specific foundation for protection and restoration of regional eco-environment to explore changes in its values of ecosystem services. This study aims to qualify long-term changes in land use of Songnen plain from 1980 to 2000, and to explore the impact of land use change on ecosystem services. With 2-period land use data using RS and GIS, this paper analyzed changes in land use and in ecosystem service values using the ecosystem service value coefficients (VC) put forward by Costanza et al. Results showed that from 1980 to 2000, area of rangeland, water area and wetlands and area of cropland decreased, but urban area and unused land increased. Due to cropland's comparatively low VC and comparatively high VC of wetlands and water area, increment in cultivated land could not offset the total decrement in regional ecosystem service values because of the decrease in area of wetlands and water area. Meanwhile, city sprawl has also led to loss of ecological values. Total ecosystem service values of the study area reduced dramatically, from 34,926.10×106$ to 31,744.54×106$ in the period 1980-2000. This represents a 9.11% net decline in annual value of ecosystem services in the study area.展开更多

By appraising the ecological damage value of the environmental risk of marine chemical spills, we can facilitate decision-making for the development of a coastal zone and establishment of economic policy on coastal zone management. In this study, the ecological effect of the environmental risk of a chemical spill in the Haicang chemical industrial park in Xiamen was identified, after which its impact was forecasted and its ecological damage value was assessed. The information generated in this study will be useful in future studies evaluating marine ecological compensation based on environmental risk analysis.展开更多

In addition, the change of ecosystem services due to land use change was estimated by the method of vaulting global ecosystem services. The result shows that there were rapid increases in the area of cropland, saline-alkaline land, and dramatic decreases in grassland, water area and wetland between 1986 and 2002. The annual value of the ecosystem services was declined from 767.1 ×10s Yuan/a in 1986 to 624.1 × 10s Yuan/a in 2002, the estimated annual ecosystem service value declined by 18. 6 % （i. e. 1.6% per year） between 1986 and 2002. It indicates that there had been a sever harm to ecosystem functions and services, which results from the deterioration of ecological environment and the adjustment of land use that aim to currently economic benefit.展开更多

Breeding cycle is one of the main patterns of ecological animal husbandry development, but breeding cycle does not form a relatively closed cycle of endogenous resources. In recent years, forage value and ecological value of mulberry have made some progresses in different research areas and angles, but the thought and practice of both forage and ecological value of mulberry has not been systematically interpreted and researched. Based on the short board of animal husbandry development and the advan- tage of mulberry, animal husbandry and mulberry were complemented and fused, and relatively closed planting and raising ecological recycling pattern with mulberry as the axis was raised. Phased scientific research and production test data were obtained, and the problems and development suggestions were put forward in the following aspects ： selection of mulberry varieties with both forage and ecological value, cost control of mulberry with both forage and ecological value, quality and safety control system of forage mulberry, orientation of feeding value of forage mulberry.展开更多

And the grades of ecological risk are assessed. According to the results of assessment, the ecological risk grades of the basin are divided into five classes. From the first grade risk to the fifth grade risk, the values of regional risk indices gradually reduce. The first grade risk areas mainly distribute in Niyang river and its branches downstream and the surrounding areas of main towns. And the basin area of non-valley region and the headstream regions of the branches are the fifth grades risk areas. This evaluation results provide the basis to the regional sustainable development.展开更多

Due to the influence of historical conditions and development stages in China, research on the realization of ecological valuations has lagged. In the new era, the construction of an ecological civilization guided by the "Two Mountains" theory has been promoted to the national strategic level and is supporting the growth of theoretical research and practical exploration based on the understanding of ecological product values. We want to innovate and improve the system used to realize the value of ecological products by applying the existing research, which focuses on the concept definition of ecological products and their correlation theories. Through systematic expansion and upgrades in this system, the evaluation accuracy of ecological products can be improved, providing valuable references for further practical exploration and promoting an ecological culture in China.展开更多

文摘Shanghai is a coastal metropolitan city with various types of natural wetlands, which account for 23.5% of its total area. According to the definition of wetland in Ramsar Convention on Wetlands, the wetlands of Shanghai were classified into 4 types: coastal, riverine, lacustrine, and reservoir and pond wetlands. In order to examine the roles of wetlands in the life-support system of Shanghai, we calculated the area of each type of the wetlands using GIS technique, and then measured the ecological service values of different ecosystems in Shanghai based on the classification of ecosystem services proposed by COSTANZA et al. (1997). The estimated annual value of ecosystem services in the study area was 7.3×109US$/a for the total area of 1 356 700ha, among which about 97% was provided by the wetlands. Effective conservation and management of wetlands are therefore crucial to Shanghai’s sustainable development. The limitations of the evaluation method for ecosystem service value were also discussed in the present paper.

By appraising the ecological damage value of the environmental risk of marine chemical spills, we can facilitate decision-making for the development of a coastal zone and establishment of economic policy on coastal zone management. In this study, the ecological effect of the environmental risk of a chemical spill in the Haicang chemical industrial park in Xiamen was identified, after which its impact was forecasted and its ecological damage value was assessed. The information generated in this study will be useful in future studies evaluating marine ecological compensation based on environmental risk analysis.
文摘According to interpreting the LANDSAT TM/ETM images of 1986 and 2002, the spatial-temporal characteristics of land use changes were analyzed during 16 years base on GIS. In addition, the change of ecosystem services due to land use change was estimated by the method of vaulting global ecosystem services. The result shows that there were rapid increases in the area of cropland, saline-alkaline land, and dramatic decreases in grassland, water area and wetland between 1986 and 2002. The annual value of the ecosystem services was declined from 767.1 ×10s Yuan/a in 1986 to 624.1 × 10s Yuan/a in 2002, the estimated annual ecosystem service value declined by 18. 6 % （i. e. 1.6% per year） between 1986 and 2002. It indicates that there had been a sever harm to ecosystem functions and services, which results from the deterioration of ecological environment and the adjustment of land use that aim to currently economic benefit.

文摘Ecological animal husbandry is an animal husbandry industry system integrating ecological benefit, economic benefit and social benefit. Breeding cycle is one of the main patterns of ecological animal husbandry development, but breeding cycle does not form a relatively closed cycle of endogenous resources. In recent years, forage value and ecological value of mulberry have made some progresses in different research areas and angles, but the thought and practice of both forage and ecological value of mulberry has not been systematically interpreted and researched. Based on the short board of animal husbandry development and the advan- tage of mulberry, animal husbandry and mulberry were complemented and fused, and relatively closed planting and raising ecological recycling pattern with mulberry as the axis was raised. Phased scientific research and production test data were obtained, and the problems and development suggestions were put forward in the following aspects ： selection of mulberry varieties with both forage and ecological value, cost control of mulberry with both forage and ecological value, quality and safety control system of forage mulberry, orientation of feeding value of forage mulberry.
文摘Taking Niyang River Basin as an example, applying with the indices of landscape pattern, the indices of ecological risk of ecosystems are calculated in this paper, which takes the value of ecological loss of main ecosystem as the evaluation standard and takes into account the impacts of probability or the velocity of main hazards and event of the ecosystem. And the grades of ecological risk are assessed. According to the results of assessment, the ecological risk grades of the basin are divided into five classes. From the first grade risk to the fifth grade risk, the values of regional risk indices gradually reduce. The first grade risk areas mainly distribute in Niyang river and its branches downstream and the surrounding areas of main towns. And the basin area of non-valley region and the headstream regions of the branches are the fifth grades risk areas. This evaluation results provide the basis to the regional sustainable development.

文摘Yu Yam Ancestral Garden is one of the four famous gardens in Lingnan,China.This study was carried out with the methods of survey and analysis,field measurement and selecting spatial samples methods,dividing Yu Yam Ancestral Garden into 11 plots,for undertaking initial quantitative research on the three-dimensional green biomass(TGB)and environmental ecological benefits(EEB)of the plants.The results showed thatthe arbor played a decisive role in TGB of the Yu Yam Ancestral Garden sample plot,in which the maximum contribution value was evergreen trees.And the Pearson correlation significance analysis was carried out on 11 indicators of the plant morphology and the TGB of the trees-shrubs,drawing a conclusion that the main influencing factor for TGB was the ratio of trees-shrubs,and the simulation equation was Y=2,357.67X3+176.707.EEB of the plants was positively correlated with TGB.A very good way of understanding of the correlation between the TGB of plants and their EEB was proposed,which could provide objective and quantitative theoretical reference data for the plant arrangement of arbor,shrubs and grasses in artificial garden green spaces.It is helpful to understand the importance of artificial garden green spaces ecological value.
文摘Ecological product is an innovative practice for ecological valuations in China. Due to the influence of historical conditions and development stages in China, research on the realization of ecological valuations has lagged. In the new era, the construction of an ecological civilization guided by the "Two Mountains" theory has been promoted to the national strategic level and is supporting the growth of theoretical research and practical exploration based on the understanding of ecological product values. We want to innovate and improve the system used to realize the value of ecological products by applying the existing research, which focuses on the concept definition of ecological products and their correlation theories. Through systematic expansion and upgrades in this system, the evaluation accuracy of ecological products can be improved, providing valuable references for further practical exploration and promoting an ecological culture in China.
