Abstract

Purpose. This study aims to guarantee the ecological flow of the river in the Weihe River Basin, to construct a sustainable water quantity regulation mechanism, the ecological regulation compensation is analyzed from the view of demand side and supply side.

Key issues. Weihe is the largest tributary of the Yellow River, the water problems of the Yellow River is also existed in the Weihe River. The WEIHE River is known as “the little Yellow River”. In recent years, Weihe comprehensive improvement project basically completed, the Weihe river basin water ecological environment has improved, Weihe River Basin Ecological scheduling has played a positive role. Shaanxi Province, ecological protection and construction target of Weihe basin based on the water situation, determine the different target of different ecological restoration, ecological environment of dry tributary of the main control section of the water requirement (suitable, minimum and lower limit) control index, put forward measures of water dispatching of short and long term, but is to ensure sustained and concerted development of ecological environment and social economy that must be based on the status quo, respect history, guarantee on the downstream water fair, water ecological compensation for the implementation of regional ecological regulation measures and the main maintenance of Weihe basin ecological environment.

Methodology. To ensure the sustainable coordinated development of ecological environment and social economy, must be based on the status quo, respect history, guarantee on the downstream water fair, water ecological compensation for the implementation of regional ecological regulation measures and the main maintenance of Weihe basin ecological environment. On the basis of domestic and international research on the basis of ecological scheduling, the establishment of a reasonable economic compensation system to solve the contradictions between the parties to eliminate the adverse effects of ecological scheduling. Follow the "if he use, he must compensation; who benefit (harm) who pays" principle, the establishment of compensation between the subject and the object of interest mechanism, negotiation mechanism, and compensation funds calculation and allocation mechanism and compensation standard system framework.

Results. Based on the policy, legal, economic, social, ecological and environmental perspective, and puts forward some effective measures to protect water ecological compensation ecological scheduling in the Weihe River basin, including many aspects of system, management and technology. Some advice is given from the supply side (such as loss of ecological regulation, hydropower station, reservoir irrigation area), and the demand side (the water along the river government administrative departments, people and other ecological system of water ecological compensation spokesman).

Results implications. The study is believed to be of a referential value for policy-making in the water management in the WEIHE River basin under the changing environment.
