Water resource energy efficiency extension ecological evaluation method based on improved distance

Abstract

The invention relates to a water resource energy efficiency extension ecological evaluation method based on an improved distance. The method comprises the following steps: water resource energy efficiency data of an object to be evaluated is obtained in various investigation ways, a comprehensive evaluation index system represented by multidimensional matter elements is established, an ideal region, a feasible region and an optimal value are obtained through the set of an expected value, correlation function calculation of each evaluation index is realized so as to carry out initial evaluation, each index of the evaluation object meeting the requirement is normalized, four different weight coefficient assignment methods are compared to give the superiority of a weight coefficient method based on the improved distance, and the extension evaluation result and the difference are analyzed. The invention provides the evaluation method with balanced weight coefficient assignment, a simple and clear evaluation way and an objective and fair evaluation result.

Description

technical field [0001] The invention proposes a method for determining the weight coefficient of water resources energy efficiency evaluation index based on the improved extension distance and applying the extension ecological evaluation method to comprehensively evaluate the water resources energy efficiency. Background technique [0002] With the rapid development of the economy and the increasing frequency of human activities, the impact on water resources is also increasing. Water resources are important natural and economic resources, and play an irreplaceable role in ensuring the sustainable development of society and economy. At present, my country's water resources are facing major problems such as uneven distribution of water resources, shortage of quantity, unreasonable development, poor management, serious water pollution and damage to the water environment. Therefore, how to rationally develop, utilize, protect and manage water resources is a long-term problem. i...

Problems solved by technology

[0005] The characteristics of water resources data are: the large amount of evaluation index data, the strong correlation between evaluation indicators and other main characteristics. Systematically establishing a water resources evaluation index system, taking into account the influence relationship between different indicators, is still a kind of The static processing method of evaluation features lacks quantitative analysis of the coupling relationship between different evaluation features, and it is difficult to reflect the degree of deviation between the proposed mathematical model and the actual working conditions
