Abstract:: Miyun reservoir is not only the main surface drinking water source,but also the ecological conservation area in Beijing. With the rise of water level and the construction of soil and water conservation project in Miyun reservoir,a series of changes have taken place in its ecological environment. In order to provide a certain reference for the control and prevention of soil erosion in this area,differential vegetation coverage can restrict non-point source pollution. Five indicators such as total nitrogen(TN),total phosphorus(TP),chemical oxygen demand(COD),biological oxygen demand(BOD₅),and total organic carbon(TOC)under natural rainfall conditions were studied by constructing 8 field standard runoff plots with different vegetation configurations. The results show that:(1)under natural rainfall conditions,the best runoff reduction effect was exerted by Castanea mollissima + Sophora flavescens plot,the average runoff reduction was 70.58%,the worst effect was exerted by Castanea mollissima + Bromus japonicus,but Castanea mollissima + Bromus japonicus still reduced the runoff by 56% compared with the single Castanea mollissima species;(2)the intercropping model of Sophora flavescens,Medicago sativa,Menthahaplocalyx,Buchloe dactyloides and Castanea mollissima could effectively reduce the loss of phosphorus in slope farmland,and the intercropping model of Bromus japonicus and Castanea mollissima could reduce the nitrogen loss of slope farmland to a certain extent; in addition to Bromus japonicus and Castanea mollissima intercropping plots,the reduction rates of COD,BOD₅ and TOC in runoff of other intercropping plots were 29.10%～95.04%,31.49%～93.60% and 16.76%～62.17%,respectively;(3)intercropping Castanea mollissima and Sophora flavescens had the best effect on reducing TN,TP and other non-point source pollution indicators,and its allocation effect was the best. Comprehensive evaluation was the most suitable for large-scale promotion.
