Embodiment 1

[0031] like figure 1 As shown, in this embodiment, a method for determining the priority of ecological water use and economic and social water use is provided, including the following steps:

[0032] S1. Carry out demand analysis for ecological water use;

[0033] S2. Carry out demand analysis of economic and social water use;

[0034] S3. Check whether the maximum demand for ecological water and economic and social water exceeds the total regional water resources;

[0035] S4. According to the test results, rank the needs of ecological water and economic and social water at all levels;

[0036] S5. Assign points to the ranking results of various levels of demand for ecological water and economic and social water;

[0037] S6. Summarize the scoring results to obtain the total score of ecological water use and economic and social water demand at all levels;

[0038] S7. Sort and prioritize the total score of each water demand.

[0039]It can be seen from the above steps th...

Embodiment 2

[0073] In this embodiment, taking the Weihe River Basin in Shaanxi Province as an example, the execution process and the superiority of the method of the present invention are described in detail.

[0074] The Weihe River Basin in Shaanxi Province has rapid economic and social development and dense population, but the total amount of regional water resources is limited. There is a big contradiction between ecological water use and economic and social water security. It is necessary to scientifically and rationally determine the priority of ecological water and economic and social water.

[0075] 1. Demand analysis of ecological water.

[0076] The watershed management agency proposes that the appropriate demand for ecological water use Ea = 2 billion cubic meters, the elastic demand for ecological water Eb = 1.2 billion cubic meters, and the basic demand for ecological water Ec = 500 million cubic meters.

[0077] 2. Economic and social water demand analysis

[0078] The hous...

Abstract

The invention discloses a method for determining the priority of ecological water consumption and economic and social water consumption, and the method comprises the following steps: S1, carrying out the demand analysis of ecological water consumption; s2, carrying out economic and social water demand analysis; s3, checking whether the maximum demand of ecological water and economic and social water exceeds the total amount of regional water resources or not; s4, sorting each level of requirements of ecological water consumption and economic and social water consumption in combination with an inspection result; s5, assigning scores to sorting results of the demands of each level of ecological water consumption and economic and social water consumption; s6, summarizing the score assignment results to obtain a total score of each level of demands of ecological water consumption and economic and social water consumption; and S7, sorting the total scores of all the water demands and determining a priority sequence. The method has the advantages that the water consumption type which should be preferentially met under the condition that the total amount of water resources is limited can be determined, fairness and efficiency can be considered, all water consumption parties can easily accept, and support is provided for optimal configuration of the water resources.

Description

technical field [0001] The invention relates to the technical field of water resource allocation and ecological environment protection, in particular to a method for determining the priority of ecological water use and economic and social water use. Background technique [0002] In the natural state, regional water resources are mainly collected in river channels and underground aquifers, which can meet the needs of natural ecology. After the emergence of human beings, they began to draw water from nature for production and life. In the past economic and social underdevelopment period, the water intake was small and the disturbance to the nature was not large, which could keep the river basin ecosystem at a good level. However, with the development of the economy and society, the demand for water in the economy and society has grown rapidly, and the amount of water withdrawn from river channels and underground aquifers is increasing. For areas with limited water resources, ...
