昆明盆地地下水超采区水资源评价

随着经济快速发展，昆明盆地淡水资源供需矛盾日益加剧，部分地区地下水超采严重。为合理开发、利用与保护地下水资源，根据地下水位动态变化以及其引发问题等因素评价了昆明盆地地下水超采情况，并划定了超采区域。评价结果表明至2010年底，昆明盆地地下水总超采区面积为128 km²，属于中型超采区，且各超采区均为禁采区。同时提出了治理超采区的措施和建议，可为区域地下水资源的科学管理提供技术支撑。

Assessment of Groundwater Overdraft Zones in Kunming Basin

The imbalance between supply and demand of fresh water resources in Kunming basin gradually exacerbates along with the social and economic development.In some areas groundwater overdraft is severe.In order to exploit,utilize and protect groundwater resource rationally,we assessed the condition of groundwater overdraft in Kunming basin,and determined the overdraft areas according to dynamic changes of groundwater table and problems caused by the changes.Results show that up until the end of 2010,the total area of groundwater overdraft zones in Kunming basin was 128 km2,ranking as middle-sized overdraft,all in exploitation prohibited zones.Furthermore,we present some suggestions and measures for dealing with the overdraft problems.The research findings offer technical support for managing regional groundwater resources in Kunming basin.
