Cloud theory and SPA-based water resource bearing capacity evaluation method

Abstract

The invention discloses a water resource bearing capacity evaluation method based on the cloud theory and SPA, and belongs to the technical field of water resource bearing capacity. The method comprises the following steps of 1, constructing a regional water resource bearing capacity evaluation system, and obtaining the related index data of the water resource bearing capacity of a to-be-studied region; 2, according to regional water resource and economic and social development characteristics, determining a water resource carrying capacity evaluation grade and a water resource carrying capacity evaluation standard; 3, calculating an index weight through a cloud theory; and 4, calculating a membership degree based on a set pair analysis (SPA) method to obtain a comprehensive evaluation result. According to the present invention, by starting from the three aspects of the total water resource amount, the water resource strength and the ecological environment, a set of regional water resource bearing capacity evaluation method with the universal applicability is established, and a scientific basis is provided for the strictest water resource management and the water ecological civilization construction.

Description

technical field [0001] The invention belongs to the technical field of regional water resource carrying capacity evaluation, and relates to a water resource carrying capacity evaluation method based on cloud theory and SPA. Background technique [0002] With the continuous progress and development of the economy and society, the contradiction between the supply and demand of water resources in my country is prominent, and the shortage of water resources and the deterioration of the water environment have hindered the sustainable development of the social economy. The total amount of water resources in my country is abundant, but due to the limitation of technical level and natural environmental conditions, the utilization rate is low. The social and economic development of many cities has exceeded the carrying capacity of water resources, resulting in the stagnation of social and economic development and the inability to improve people's living standards. To solve the proble...
