A primary study on Chinese terrestrial ecosystem services and their ecological-economic values

摘要: Ecosystem services are the conditions and processing through which natural ecosystems species,that make them up,sustain fulfill human life.They not only supply to being with production of ecosystem goods,but also perform fundamental life support services,which include purification air water,detoxification decomposition wastes,regulation climate,regeneration soil fertility,and maintenance biodiversity,mitigation floods droughts.The Chinese their indirect economic values were estimated based on ecological function analysis.The study showed that in RMB organic matter production,CO_(2) fixation,O_(2) release,nutrient recycle,soil protection,water holding capacity environmental 1.57×10~(13) Yuan/a,2.84×10~(2) Yuan/a,2.84×10~(12) Yuan/a,3.24×10~(11) Yuan/a,5.69×10~(12) Yuan/a,2.71×10~(11) Yuan/a,4.90×10~(12) Yuan/a,respectively.
