| 摘 要： | 借鉴生态补偿研究中生态价值当量的思路,构建森林、草地、农业用地、湿地、河流湖泊和荒地6类不同生态系统指标,对赣江流域的生态经济价值进行测算与分析。结合以生态服务功能价值为基本依据的生态补偿,引入经济学中的博弈论,以赣江流域上游的赣州市和下游的南昌市为例,建立流域生态补偿模型。结果表明:基于修正系数下赣江流域2013年的生态价值当量为730.16万,生态经济价值为46.85亿元,各县域的生态价值当量和生态经济价值差异均较大且二者表现高度一致。从生态价值当量看,最小值为赣州市区的2.87万,最大值为宁都县的31.36万;从生态经济价值来看,最大为宁都县的2.04亿元,最小为赣州市区的0.18亿元。空间上看,赣江流域的生态价值当量和生态经济价值存在一定的地域分异规律,上游明显优于中下游,高值区域集中分布在梅江流域的宁都县、兴国县等县域,低值中心分布在除宜春市区外流域内的各个地级市区,其中林地生态系统的贡献最大,比重达58.98%。利用2004—2013年赣州市的GDP数据和环保投入与南昌市的GDP数据,结合博弈论分析得到上下游的补偿额度在91.53亿~113.18亿元之间。

Eco-compensation and Ecological Value in Ganjiang Basin |
| |
| Abstract: | According to the ecological value equivalence, six different ecosystems indicators of forest, grass-lands, agricultural lands, wetlands, rivers-lakes and desert were constructed with the help of six ecosystems data of Ganjiang Basin in 2013. Ecological compensation is an important economic instrument to coordinate regional eco-nomic development, protect the ecosystem. This paper introduced the economic game theory and established ecolog-ical compensation model by examples of Ganjiang Basin downstream of the Nanchang and upstream of Ganzhou. County ecological value equivalent and ecological value are differ huge in Ganjiang Basin, a maximum of Ningdu reached to 31.36 ten thousand and 2.04 one hundred million yuan(RMB), the minimum is Ganzhou reached to 2.87 ten thousand and 0.18 one hundred million yuan( RMB) , the county’ s gap of more than 150 times. Upstream county is much better than downstream in Ganjiang Basin, high value area concentrated in Ningdu, Xingguo and other counties in Meijiang Basin, low value area is located at urban other than Yichun City. The ecological value of woodland ecosystems contribute the largest proportion in the basin, up 58.98%. The game theory analysis indicates that the eco-compensation value of the basin is at the range of 91.53 one hundred million yuan( RMB) and 113.18 one hundred million yuan ( RMB) . |
