基于集对分析模型的水源地水资源脆弱性评价——以恩施市为例

Vulnerability assessment of water resources based on set pair analysis model--take Enshi as an example

水资源脆弱性评估是水资源保护的重要决策依据。文章以恩施市16个乡镇20个水源地2016-2018年水资源数据为基础,构建出恩施市水资源分级标准得到脆弱性评价样本值;利用集对评价法对恩施市水源地水资源脆弱性进行评价分级,结果表明2016-2018年恩施市水资源为轻度脆弱,其中造成脆弱性低的主要指标为人均水资源和亩均水资源不足。

Under the condition of limited human resources,it is difficult to give full play to the resource potential and pursue the maximization of the number of trees planted.The tree planting problem should be optimized.This paper puts forward several ideas to analyze and solve the tree planting problem,in order to provide reference for relevant personnel.Water resources vulnerability assessment is an important decision-making basis for water resources protection.Based on the water resources data of 20 water sources in 16 townships and towns of Enshi City from 2016 to 2018,this paper constructs the water resources classification standard of Enshi City,and obtains the sample value of vulnerability evaluation;The set pair evaluation method is used to evaluate and grade the vulnerability of water resources in water sources in Enshi City.The results show that the water resources in Enshi City are slightly vulnerable from 2016 to 2018,and the main indicators of low vulnerability are the shortage of water resources per capita and per mu.
