摘要:

本文以完善玉溪市水资源的安全管理、实现水资源可持续利用为目的,以玉溪市县级行政区为研究对象,选取评价指标并利用基于“熵权”的模糊综合评价模型,对玉溪市平水年、枯水年、丰水年水资源承载力进行研究。结果表明:玉溪市水资源承载力存在显著时空异质性,空间总体上呈现“西高东低”的格局,丰水年水资源承载力最高,枯水年与平水年承载力相近。其中位于玉溪市东部的澄江县、江川区、通海县、华宁县在平水年和枯水年属于低承载地区,西部新平县、元江县和中部红塔区属于中承载力地区。丰水年东部通海县、江川县及中部易门县属低承载力区,西部的新平县属高承载力地区,其余各县为中承载力地区。玉溪市的水资源承载力与各区当年的水资源禀赋、供需状况、经济发展程度、生态环境状况密切相关。

Water resources carrying capacity assessment has a great significance for the safety management and sustainable utilization of water resources and the development of city construction. We took Yuxi counties as the case study and selected evaluation indexes to assess the water resources carrying capacity in normal, dry and wet years by the fuzzy comprehensive assessment model based on “entropy”. The results show that there is a significant temporal and spatial heterogeneity on the water resources carrying capacity in Yuxi. The water resources carrying capacity decreases gradually from east to west. The eastern counties of Yuxi in the normal and dry years which are Chengjiang, Jiangchuan, Tonghai and Huaning belong to the low bearing area. Xinping, Yuanjiang located in the west and central Hongta district belong to the medium carrying capacity district. In the wet year, the eastern county of Tonghai and Jiangchuan, central county of Yimen is low carrying capacity. Xinping located in the west belongs to high carrying capacity area. And the rest of counties belong to medium bearing capacity area. The water resources carrying capacity is depend on the endowment and supply-demand ratio of water resources, the degree of economic development and ecological environment.
