Abstract:
【Objective】The ecological, economic and social characteristics of the headwaters of rivers are prominent, and conventional ecological compensation methods are not applicable in the headwaters of rivers. Therefore, dominant ecological function method (DEFM) is proposed to calculate the amount of ecological compensation. 【Method】Separate weights are assigned to the main function and the minor function respectively, and the weights are determined by means of the Pearl curve or the proportion of land use. These weights are used to calculate the main function value and the secondary function value. A case study was conducted in the headwater region of the An-ning River Basin, a tributary of Yalong River, compared with the results conventional ecological compensation methods. 【Result】Amount of ecological compensation : Ecosystem service value (2315 million)＞DEFM1(589 million)＞DEFM2(568 million)＞The opportunity cost(493 million)＞Contingent value method(192 million). After the implementation of ecological compensation in accordance with the DEFM, the gap between the average financial income of tourists from the top and bottom of the headwater region has narrowed from 2.5 times to 1.1 times. 【Conclusion】The DFEM proposed in this study fully considers the ecological characteristics of the headwater area, the stage of social development, and the affordability of the compensation subject, which can effectively adjust the upstream and downstream profit and loss relationship in the source area. The determination of main and minor functional value weights is objective.
