为分析掌鸠河引水供水工程、清水海供水及水源环境管理项目供水工程、牛栏江-滇池补水工程等外流域引水工程建成后的滇池运行控制水位,基于滇池、海口河-螳螂川流域现状经济社会发展、长系列水文观测、供用耗排水等数据资料,采用径流还原、湖泊径流与洪水调节模拟等方法,经多方案比较确定滇池外海的正常高水位提高至1887.50 m,汛期限制水位提高至1887.20 m,在滇池泄洪通道和预报调度系统未达到设计标准前,汛期限制水位可降至1886.70 m运行；将外海自正常高水位以下依次划分为生态供(用)水区、工农业供水区、死水位区。研究结果表明,滇池从过去的调蓄供水水源转变成需进行生态修复补水的用水对象,将促使昆明城市及环湖周边高耗水行业转移到下游的海口-安宁地区,减少滇池水资源的一次性消耗量,削减入湖污染物,形成以水定发展的局面,从而实现工业布局的战略性调整。

In order to analyze the water level of Dianchi Lake after the construction of several inter-basin water diversion projects, including the Zhangjiu River Water Diversion and Supply Project, the water supply project of the Qingshuihai Lake Water Supply and Water Sources Management Project, and the Water Diversion Project from the Niulanjiang River to Dianchi Lake, data from the investigation of current social and economic development, long-term hydrological observation data series, and water supply, utilization, consumption, and drainage data series from the Dianchi Basin and the Haikouhe-Tanglangchuan Basin were collected. Then, the runoff reduction method and a simulation method for lake runoff and flood regulation were adopted. Through comparison of multiple schemes, reasonable values of the water level of Dianchi Lake were determined as follows:the normal pool level was set to 1 887.50 m, and the limiting level during the flood season was set to 1 887.20 m. Unless the spillway of Dianchi Lake and the forecast and operation system are built, the limiting level during flood season should not exceed 1 886.70 m during operation. The areas in the outer lakes of Dianchi Lake with a water level beneath the normal pool level were divided into the ecological water supply ( utilization) area, the industrial and agricultural water supply area, and the dead storage area. The results show that Dianchi Lake has changed from a former water supply source into a water body that has to be supplemented with water for ecological rehabilitation, and that the high water consumption industry in Kunming City and areas around Dianchi Lake has to be moved to the downstream Haikou-Anning area in order to reduce the consumption of water resources in Dianchi Lake and the contaminants into the lake. Therefore, the social and economic development will be guided by the water resources situation, and the strategic adjustment of the industrial layout will be achieved.
