Abstract: The imbalance between supply and demand of fresh water resources in Kunming basin gradually exacer-bates 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.
