水权交易模式下江西流域生态与经济耦合关系研究

由于生态补偿资金不足、补偿标准难以确定等问题,导致流域内发展两极分化较为严重,普遍存在"上游保护地区发展缓慢,下游地区免费受益"现象。通过引入以水权交易为补偿模式的生态补偿机制,构建江西流域生态与经济耦合关系,有效实现下游地区对上游地区因流域生态保护失去发展权的补偿,平衡流域内不同行政区经济发展,为江西省统筹生态建设与经济发展提供方向。在机会成本法的基础上,引入水质系数1/IP综合、单位用水经济效率系数1/E以及协商系数β,建立江西流域生态补偿模型。以赣江南昌、宜春段为例,计算得出2012年的补偿额度应为20.890 3×β亿元。通过结合两地实际经济发展水平,设定协商系数β的合理取值范围,最终确定具有实际操作意义和运用价值的补偿额度。

Coupling Relationship between Watershed Ecology and Economy of Jiangxi Province under Water Right Trade Mode

Insufficient compensation funds, difficulties in making compensation standard and other problems result in great development gaps between different areas in the watershed, which has become the widely known as the phenomenon of upstream areas develop slowly and downstream areas benefit freely. right trade as compensation mode into the ecological compensation mechanism, and estab This paper places water lishes the coupling rela- tionship between watershed ecology and economy of Jiangxi Province, aiming to balance the economic develop- ment of different administrative regions in watershed and provide methods for comprehensive planning between watershed ecological construction and economic development of Jiangxi Province.A watershed eco-compensation model is constructed for Jiangxi Province based on opportunity-cost method and the adoption of such concepts as coefficient of water quality（ 1/IP综合）, coefficient of efficiency of GDP produce amount per cubic meter water use（1/E） and coefficient of negotiation（β）.Taking the section of Ganjiang River from Nanchang to Yichun as example,the compensation standard of year 2012 could be 2.0890 3×β billion RMB.With the consideration of economic development levels of these two places, reasonable data range of coefficient of negotiation （β） could be set. Finally, the compensation standard of practical operation significance and applying value could be confirmed.
