【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。
[Abstract]:Based on the idea of ecological value equivalent in ecological compensation research, six kinds of different ecosystem indexes, such as forest, grassland, agricultural land, wetland, river, lake and wasteland, are constructed. This paper calculates and analyzes the ecological economic value of Ganjiang river basin and introduces the game theory in economics by combining ecological compensation based on the value of ecological service function. Taking Ganzhou City in the upper reaches of the Ganjiang River Basin and Nanchang City in the lower reaches as examples, a watershed ecological compensation model is established. The results show that the ecological value equivalent of Ganjiang river basin in 2013 is seven million three hundred and one thousand and six hundred based on the correction coefficient. The ecological economic value is four billion six hundred and eighty-five million yuan. The difference of the ecological value equivalent and the ecological economic value of each county is great and the two are highly consistent. The minimum value is 28,700 of Ganzhou city and the maximum value is 313,600 of Ningdu county. From the ecological economic value, the largest is 204 million yuan of Ningdu County, and the smallest is 18 million yuan of Ganzhou urban area. The ecological value equivalent and ecological economic value of Ganjiang river basin have certain regional differentiation law, the upstream is obviously superior to the middle and lower reaches, and the high value area is concentrated in Ningdu county and Xingguo county of Meijiang river basin. The low-value center is distributed in every prefecture-level city area except Yichun city, in which woodland ecosystem contributes the most. The proportion is 58.98. Using the GDP data of Ganzhou City from 2004 to 2013 and the environmental protection input and the GDP data of Nanchang City. Combined with game theory analysis, the compensation amount of upstream and downstream is between nine billion one hundred and fifty-three million and eleven billion three hundred and eighteen million yuan.

【正文快照】： 0引言生态系统是人类社会的支持系统。然而,长期以来人类对生态价值的忽视、人与自然关系的错位导致人们对自然资源竭泽而渔式地过度开发,使生态平衡遭到破坏,人们不得不在获得巨大经济效益的同时付出各种环境代价,科学地评价生态系统服务功能,有助于人地系统更为和谐[1-4]。
