Method for reasonably using domestic water in drainage basin

Abstract

The invention discloses a method for reasonably using domestic water in a drainage basin, which comprises the specific steps of: carrying out investigation and analysis on population growth, development and utilization of water resources and the current situation and the variation tendency of the water use efficiency in the drainage basin; analyzing population variation characteristics and combining upstream and downstream characteristics to respectively calculate ratios of rural population and urban population; analyzing upstream and downstream water use efficiency difference characteristics in the drainage basin and calculating an upstream and downstream water use efficiency difference characteristic index; constructing a binary structure model and calculating a water use Gini coefficient in the drainage basin; and calculating water use Gini coefficients in the drainage basin in different target years and drawing a variation curve of the domestic water Gini coefficient in the drainage basin so as to totally evaluate the fairness and reasonability condition of the water utilization in the drainage basin and give service to the planning and management of the water sources in the drainage basin. The binary structure water use Gini coefficient model constructed in the method is comprehensive and accurate for a water use evaluation result, has high confidence level and can effectively reflect the fairness and reasonability using condition of the domestic water in the drainage basin.

Description

technical field [0001] The invention belongs to the field of water resources application, in particular to a method for rationally using domestic water in a river basin. Background technique [0002] The primary issue for the rational use of domestic water is the fairness of water consumption. The fairness of water consumption is the most basic issue in water distribution, directly related to the most realistic vital interests of the people, and is the core issue of sustainable use of water resources. With the acceleration of urbanization in my country, the shortage of water resources has become an important restrictive factor for the sustainable development of my country's economy and society. Coupled with the uncertainty of global warming, the contradiction between supply and demand of water resources in my country will become more prominent in the future. Therefore, how to ensure the fair distribution of limited water has become an important part of the development of peo...
