| Abstract: |
| 【Objective】Ecological and socioeconomic characteristics of headwater of a river are unique and its ecological compensation cannot be calculated using the conventional ecological compensation method. The purpose of this paper is to present a dominant ecological function method (DEFM) to resolve this problem.【Method】Different weights were assigned to the main function and the minor function, and the values of the weights were determined by the Pearl curve or proportion of the land use. These weights were then used to calculate the main function and the secondary function. The model was applied to a headwater region in Anning River Basin - a tributary of the Yalong River. The results obtained from the proposed method were compared with those obtained from the conventional ecological compensation method. 【Result】The amount of ecological compensation was ranked in: Ecosystem service value (2 315 million)>DEFM1 (589 million) > DEFM2 (568 million)>The opportunity cost (493 million) > Contingent value method (192 million). Implementing the ecological compensation based on the DEFM could reduce the difference in tourism income between the top and bottom of the headwater from 2.5 times to 1.1 times. 【Conclusion】The proposed DFEM considered the ecological characteristics of the headwater, social development level and the affordability of the compensation subject. It can effectively balance the loss and profile of both upstream and downstream of the headwater region. |
