摘　　要：水温是水体的一项重要指标参数,水温的变化将导致水体内部生态体系发生一系列的改变。以千岛湖珍珠半岛湖湾为例,在现场监测的基础上,根据实测数据建立并验证温排水数值模型,利用该数值模型进行工业企业冷却排水在湖湾中的复温范围研究。研究结果显示,冷却排水的流量和水温对湖泊中的复温范围有较为明显的影响;而冷却排水对湖泊的影响也体现出一定的季节特性:以温差2.0℃为评价标准,夏季排水对珍珠半岛湖湾的影响范围较大,冬季排水对珍珠半岛湖湾基本不产生影响。Water temperature is a critical parameter of water body. Minor change of water temperature will lead to a series of transformations on water ecological system. In this study, based on the field monitoring data, a numerical model has been established in order to simulate the thermal discharge in Pearl peninsula lake-bay in Qiandao Lake. Both the field monitoring and numerical study indicate that the discharge rate and discharge temperature will affect the impact range of the thermal discharge flow in the lake. Additionally, the seasonal characteristics of the thermal discharge are also observed：Taking 2.0 ℃ difference as the standard of evaluation.lt is anticipated that the impact range is wider in the lake in summer than in winter based on the numerical simulation.
