摘要
以流域土地利用变化、非点源污染、水利水保措施、旅游业发展以及矿山开发等人类活动作为影响因素,运用SWAT模型对密云水库1990-2005年的入库径流量及水质变化过程进行模拟。选用月径流模拟的效率系数、相对误差、相关系数作为模型适用性的评价指标。模拟结果表明,在考虑人类活动的影响下,对密云水库来水量及水质进行模拟更加符合当今复杂下垫面情况下的实际径流过程。研究结果对人类活动影响下的密云水库入库径流量及水质变化过程提供新的思路。
Based on the consideration of land use change, non-point source pollution, hydraulic projects and soil conservation measures, tourism development and mine development, the SWAT model is established to simulate the runoff and water quality of the Miyun reservoir from 1990 to 2005. The Nash coefficient, relative error and correlation coefficient of monthly runoff are selected to judge the performance of the model. The results show that the simulation with the consideration of the human impact is in good agreement with the actual runoff process and the change of water quality. This paper provides a new method for the runoff and water quality simulation of the Miyun reservoir.
