摘　　要：近十多年来 ,昆明市地下热水开采强度逐年增加 ,水位大幅下降 ,降落漏斗不断扩大 ,城区中心区范围内已开始出现越流污染、热废水污染、岩溶塌陷及地面沉降等环境地质问题 ,热水温度也在明显降低。结合区内地下热水的水文地质条件和开发利用中的环境效应问题 。The renewal capability of the geothermal water resources in the middle-lower temperature geothermal water area of Kunming is weak in recent decades. Based on the analysis on the monitoring data of the geothermal water exploitation well, it is founded that, with concentrated and rapid withdrawal of geothermal water, the level of geothermal water is declining continuously, and the depression cone is expending greatly. Consequently, a series of environmental problems and geological hazards take place, such as, resources decreasing, pollution by leakage recharging, chemical pollution by waste geothermal water, Karst collapse and land subsidence etc., which have led to adverse impacts and economic losses greatly, especially in central city area. Based on the study of the environmental problems and the hydrogeological conditions of Kunming geothermal water area, the appropriate countermeasures for sustainable exploitation and utilization have been proposed, including the control of withdrawal yield, avoidance of concentrated exploitation, artificial recharge, systematical regulation and strengthening of management.
