摘要
昆明市地热田的开发利用已有 2 0多年历史 ,部分地段长期过量开采诱发的环境地质问题日趋突出。本文用 TOPSIS法和综合指数法对昆明市南市区近 10年来地下热水水质演变过程及现状作分析评价 ,研究结果表明昆明市地下热水已遭受到不同程度的污染 ,并且有恶化的趋势。
As development and making use of geothermal field in Kunming for more than 20 years, the environmental geological problems have stood out gradually because of the excessive exploitation over a long period in the places. In this paper, the quality evolution of geothermal water for nearly ten years and its present condition are analyzed and evaluated in south of Kunming by TOPSIS and the method of integrated index.
