Embodiment 1

[0093] In step 1, it is assumed that there are 10 sub-regions, which are respectively partitions 1-10. A total of 15 indicators are determined, which are the intact rate of water conservancy facilities (C 1 ), total water consumption control index ratio (C 2 ), groundwater overexploitation area ratio (C 3 ), recycled water utilization rate (C 4), population density (C 5 ), water supply network leakage rate (C 6 ), centralized treatment rate of urban domestic sewage (C 7 ), GDP per capita (C 8 ), water consumption per 10,000 yuan of industrial added value (C 9 ), irrigation water use coefficient (C 10 ), fertilizer application intensity (C 11 ), industrial wastewater discharge compliance rate (C 12 ), water quality compliance rate of water function zone (C 13 ), urban green coverage (C 14 ), water surface rate (C 15 ). The index values ​​of each partition in this embodiment are shown in the following table.

Abstract

The invention discloses a three-class six-stage water resource bearing state early warning method based on a variable fuzzy method. The method comprises the following steps of establishing a water resource bearing state early warning index system, constructing a multi-factor comparison matrix, calculating an index weight through an analytic hierarchy process, measuring the bearing state of a waterresource system by using a variable fuzzy method idea, and obtaining an evaluation result of the water resource bearing state; and grading the evaluation results, and obtaining an early warning result of the water resource bearing state according to the bearing states of different years and the change trend conditions of the bearing states. According to the method, an analytic hierarchy process is adopted, and the subjective judgment and reasoning of a decision maker can be closely associated; secondly, based on a variable fuzzy method, the evaluation result is prevented from being too abstract, the evaluation result value is not consistent with the connotation of the water resource bearing state, a basis is provided for determining the direction for improving the water resource bearing state and making improvement measures, and the method has very high practicability and wide applicability.

Description

technical field [0001] The invention relates to a water resource evaluation and allocation method, in particular to a three-category six-level water resource bearing state early warning method based on a variable fuzzy method. Background technique [0002] The evaluation of water resources bearing status is used to characterize the current status of regional water resources supporting socio-economic, ecological and environmental systems, and to give early warning of possible future situations. The evaluation results are relatively objective, and the value of the evaluation results is in line with the connotation of the water resources carrying status, which enables decision makers to make an evaluation decision on the water resources carrying status of a region more simply and quickly, and to determine the direction to improve the water resources carrying status, formulate It provides a basis for improvement measures, and has the advantages of strong practicability and wide ...
