生态补偿的计算方法是当前生态补偿研究的重点和难点。本研究以污染物排放总量的容量控制为目标，采用生态补偿方法，考察流域内行政级别上的生态经济系统之间以及流域上下游地区之间的自然、社会和经济相互作用。采用信息熵方法建立了污染物总量分配模型，模型中包含了一系列反映人口、经济结构、生产水平、污染控制和水环境等因素区域异质性的指标。利用投入资金与污染物排放量的关系，计算污染物的单位价值，构建基于污染物总量控制的流域水环境生态补偿标准定量模型。以小洪河流域为例，以化学需氧量（COD）为主要污染评价指标，计算了小洪河流域2008 - 2012年水环境生态补偿价值。从时间尺度上看，补偿值从上游到下游逐渐减小，而从下游到上游逐渐增大。该研究为建立流域生态保护长效机制、完善流域生态补偿制度提供了有效途径。(C)2016爱思唯尔有限公司版权所有。
The method used to calculate ecological compensation remains an important but difficult issue in current studies of ecological compensation. In this study, we used the ecological compensation method to examine the natural, social, and economic interactions between ecological and economic systems at the administrative level and between upstream and downstream areas in a river basin, with the aim of capacity control in the total amount of pollutants discharged. We used the information entropy method to build the total pollutant allocation model, in which we included a range of indexes that reflected regional heterogeneity in factors such as population, economic structure, production level, pollution control, and the water environment. The relationship between the capital invested and the quantity of pollutants discharged was used to calculate the unit value of the pollutants, from which we constructed a quantitative model of ecological compensation standard for river basin water environment based on total pollutants control. We used the Xiao Honghe River Basin, China, as a case study, and calculated the ecological compensation values of the water environment from 2008 to 2012 with chemical oxygen demand (COD) as the main pollution evaluation index. From the upper to lower reaches, the compensation value gradually decreased while it gradually increased in terms of time scale. This study provides a valid approach that can be applied to develop a long-term effective mechanism for protecting river basin ecology and improving the system of ecological compensation in river basins.
