Exploration of the Formation Mechanism of Terminal Water Price in Different Irrigation Areas
In order to understand the formation mechanism of terminal water price of different users, and provide a reference for the comprehensive reform of agricultural water prices in Jiangxi province, Ganfu Plain irrigation district was selected from 2016 to 2017 for a survey on cost, current water price and users’ bearing capacity. Ecological water was included in the survey as one of the users. According to research results, the users are divided into agricultural water users, non-agricultural water users, and ecological water users. Apportion coefficient method is used to calculate the terminal water price of different types of users. The reasons for the change of terminal water price that include ecological water use in the large scale irrigation are analyzed. Finally, according to the water user affordability the executable water prices range in Jiangxi Province are put forward. The results will provide a reference for the agricultural water price reform in irrigation area.
