摘　　要：为解决因非点源污染造成的地表水环境污染问题,提出基于AnnAGNPS模型的地表水环境非点源污染模拟方法。通过计算地表水最终含水量、汇流时间和水位曲线、地表水基流分析地表水环境AnnAGNPS模型。并基于自然地理概况,联合已划分的污染子流域对象,处理水文/水质数据,获取地表水环境非点源污染数据,分析模拟实验结果可知,STD指标数值随着时间的增加而增加,而SPD指标随着时间的增加而增加,但整体增长速度较慢,需要适当减少含磷类化肥的实际应用量可有效缓解地表水非点源污染情况。In order to solve the problem of surface water environmental pollution caused by non-point source pollution,a simulation method of surface water environmental non-point source pollution based on AnnAGNPS Model is proposed.The AnnAGNPS Model of surface water environment is analyzed by calculating the final water content,confluence time,water level curve and surface water base flow.Based on the general situation of physical geography,the hydrological/water quality data are processed to obtain the non-point source pollution data of surface water environment by combing with the divided pollution sub watershed objects.The analysis and simulation experimental results show that the value of STD index increases with the increase of time,while the SPD index increases with the increase of time.The overall growth rate is slow,however.It is necessary to appropriately reduce the practical application of phosphorus containing fertilizers,which can effectively alleviate the non-point source pollution of surface water.
