Embodiment Construction

[0060] The technical scheme of the present invention is described in further detail below:

[0061] A water-related ecological environment carrying state measurement model, comprising the following steps:

[0062] Step 1: Determination of the bearing status measurement index system

[0063] The level of water resource surplus and shortage is represented by the water resource surplus and shortage index WI, and the indicators include per capita water resources, effective use coefficient of farmland irrigation water and water resource utilization rate;

[0064] The water-related ecological environment quality is represented by the water-related ecological environment quality index EE, which includes COD emissions, ammonia nitrogen emissions, vertical river connectivity, urban river and lake water quality, river ecological water demand guarantee rate, water quality River length ratio, river bank curvature, vegetation coverage, biological abundance index, water surface rate and so...

Abstract

The invention provides a water-related ecological environment bearing state metering model. The water-related ecological environment bearing state metering model is a metering model for evaluating thebearing state of a social economic system by establishing a water-related ecological environment system for Yangtze River southern water quality type water-deficient areas such as a Taihu lake basin.According to the sustainable development principle, aiming at the key water-related ecological environment problem of a research area, a metering index system of a bearing state is created, and the water-related ecological environment quality-social economic level comprehensive measurement model is constructed, and specific membership function is introduced for scaling. The model solves the problems existing in the prior art, and can evaluate the water-related ecological environment bearing capacity of a research region in a certain time period.

Description

technical field [0001] The invention belongs to the technical field of hydrology and water ecological environment, and relates to a water-related ecological environment carrying state measurement model. Background technique [0002] In China, the research on water resources carrying capacity began in the late 1980s, represented by the Xinjiang Water Resources Soft Science Research Group’s research on Xinjiang’s water resources carrying capacity, but the concepts, theories and calculation methods at that time were all It was in its infancy, and before 1995, the research was not extensive, and the research methods used were relatively simple, mainly using trend analysis. From 1995 to 2003, water resources carrying capacity has been extensively studied and has entered a stage of great development. The research methods are diversified, mainly including comprehensive evaluation method, system dynamics method and multi-objective optimization method. From 2003 to the present is th...
