Water resource system sustainable development evaluation method considering uncertainty and subjective and objective weight combination

Abstract

The invention discloses a water resource system sustainable development evaluation method considering uncertainty and subjective and objective combination. The method comprises the following steps: determining second-level and third-level development targets according to a first-level target of sustainable development of a regional water resource system; obtaining an evaluation index according to the three-level development target and a screening principle; respectively using an analytic hierarchy process and an entropy weight method to determine weight matrixes, and obtaining a comprehensive weight matrix based on the two weight matrixes; standardizing the measured value of the evaluation index to obtain a dimensionless matrix; calculating an evaluation value of each secondary development target according to the comprehensive weight matrix and the dimensionless matrix; rating the evaluation value of each secondary development target by adopting an expert scoring method; calculating an uncertainty matrix and expectation thereof according to an expert scoring result; and calculating the comprehensive sustainable development degree of the region according to the evaluation value of each secondary development target and the uncertainty matrix. The method can effectively avoid uncertainty of a sustainable development evaluation result, and can effectively improve objectivity and scientificity of the evaluation result.

Description

technical field [0001] The invention relates to an evaluation method for sustainable development of a water resource system considering uncertainty and combination of subjectivity and objectivity, belonging to the field of water resource management. Background technique [0002] Water resources are basic natural resources and strategic economic resources, and are the basic support for social and economic development. The sustainable development status of the water resource system is an important basis related to whether water resources can guarantee the sustainable development of the society. Using scientific and reasonable evaluation indicators to quantitatively analyze the sustainability of the water resource system can provide comprehensive information for the comprehensive management of water resources in water-scarce areas. Providing scientific basis is of great significance for effectively avoiding the risk of water shortage and promoting the sustainable development of...
