Abstract

Abstract: Basin water ecological compensation is an effective means of coordinating environmental protection and economic development and promoting sustainable development. A reasonable compensation interval (the value range of the compensation standard) is the basis for final pricing. At present, the calculation method of the compensation interval has not been unified in the current research, and it is rarely considered comprehensively from the perspective of both parties of compensation. Based on the perspectives of upstream water resources suppliers and downstream water resources consumers, this paper proposes a water ecological compensation interval accounting method based on emergy analysis theory and water ecological footprint method. From the perspective of the supply side, the remaining ecological economic system services value supplied by the upstream area is taken as the lower limit; from the perspective of the consumer side, the value of ecological economic system services actually occupied by downstream areas is taken as the upper limit. Taking the Qingyi River Basin as an example, the results show that there is a serious ecological deficit in the lower reaches of the Qingyi River Basin, and reasonable compensation needs to be given to the supplier Xinzheng City; the accounting method based on dual perspectives is better than traditional. The method is more precise and greatly shortens the value range of the compensation standard. This study provides a novel and complete ecological compensation interval accounting method, which provides a more accurate and reasonable reference for the determination of ecological compensation standards in the basin, and helps the government to improve and implement the ecological compensation mechanism. Highlights: The study proposes a new quantification method of watershed compensation interval. Different amounts of spillover value from different perspectives. Lower Qingyi River has a high ecological deficit. Compensation interval based on dual perspective is more accurate. Compensation interval difference is mainly affected by downstream.
