摘　　要：在被规划为滇池南部重点农业区的晋宁柴河流域示范工程区汇水区内,对其3个典型断面进行了连续两年的采样监测,测定其每月河道内的流量、TN、TP及CODCr,分析3个断面上碳、氮、磷的通量年季变化规律.从测定结果看,示范工程对面源污染起到了较好的控制作用.The catchment area of the demonstration project in the Chaihe basin,which was slated for the key agriculture area of Jinning county on the south bank of the Dian Lake,has been sampled and monitored at its three different sections for two consecutive years,with the flow,total nitrogen,total phosphorus and CODCr being determinated monthly.The analysis of annual and seasonal variation in carbon,nitrogen,and phosphorus flux indicates that the demonstration project has effectively reduced the non-point pollution in this area.
