Abstract:

Trans-boundary drinking water sources involve the subject interests of protectors and beneficiaries. To ensure the long-term safety of drinking water, the ecological compensation mechanism should be urgently introduced for regulating the subject interests of upstream and downstream of trans-boundary drinking water sources. As the main mean of ecological compensation mechanism is fund compensation in Henan province, the determination of compensation standard is the core of ecological compensation research. In this paper, the difference between the cost input of upstream drinking water sources and the ecological benefits was accounted, and the ecological compensation standard of trans-boundary drinking water sources was determined based on the water quantity. Taking trans-boundary drinking water sources of Lihe in Pingdinhshan city as an example, the annual average investment of protecting Lihe drinking water sources was 20.1677 million yuan, and the ecological and economic benefits annually which were obtained by the ecological construction and ecological restoration was 12.9236 million yuan. Based on the difference between input costs and ecological benefits, the trans-boundary drinking water sources compensation standard of Lihe was determined. And the standard defines that the upstream (Pingdingshan city) should be compensated 0.13 yuan/m³ when the downstream obtained one ton drinking water from the upsteam. Taking the difference between the cost input of upstream drinking water sources and the ecological benefits as the standard which determines the ecological compensation of trans-boundary drinking water sources, not only could the net investment of upstream be estimated accurately and the compensation be determined objectively, but also could two-way incentive and restraint mechanisms of upper and lower administrative be established effectively.
