Method of allocating ecological compensation amount of river basin based on improved Shapley value.

In order to make the ecological compensation for river basin more reasonable and stimulate the water ecological protection initiatives of the upstream region, the water ecological compensation amount allocation method is proposed based on the model of DEA cooperative game with the supposition of cooperation among different areas along the basin. Considering the limitation of classic Shapley value in cooperative game, this value is improved by the weight among different areas confirmed by trapezoidal fuzzy number. Applied to Xin'an River basin, its result indicates that the allocation method adopted in this paper not only made the driving force for ecoloical protection stronger, but also combined the importance of different index such as the water and its benefits in the basin, meanwhile, the water benefits was considered among different areas. Thus, it is more reasonable, and it could provide reference for the ecological compensation amount allocation research of the other basins cross regions. [ABSTRACT FROM AUTHOR]
