曲靖市水资源承载力分析
|
Abstract:
本文选择曲靖市水资源承载力为主题进行研究，选取了13个影响因子作为评价指标，并建立评价指标体系，利用AHP法确定其权重，并采用多层次模糊综合评价法对曲靖市2016~2020年水资源承载力变化情况进行分析和评价。研究结论如下：1) 曲靖市存在水资源配置不合理，第一产业用水量大，农业发展与水资源承载力不适应等问题；2) 曲靖市水资源综合承载力在2016~2020年间都处于严重超载状态，但随着经济和社会子系统的改善，曲靖市水资源承载力状况正在逐步趋好。
This paper examines Qujing City’s water resource capacity, selects 13-influencing factors as valuation indices, establishes the valuation index system, uses the AHP method to determine its weight, and uses multi-stage fuzzy comprehensive valuation method, to analyse and evaluate the changes in Qujing City’s water resource capacity from 2016 to 2020. The conclusions are as follows: 1) there are some problems in Qujing City, such as unreasonable allocation of water resources, large water consumption in the primary industry, and the incompatibility between agricultural development and water resources carrying capacity; 2) From 2016 to 2020, the comprehensive water resources carrying capacity of Qujing City was seriously overloaded, but with the improvement of the economic and social subsystem, the water resources carrying capacity of Qujing city gradually increased.
