小流域面源污染监测技术指标体系及监测方法研究

A Preliminary Study on the Technical Index System and Monitoring Methods of Non-Point Source Pollution Monitoring in Small Watersheds

小流域面污染主要针对农业生产活动产生的地表水系污染问题,农业生产中使用的有机肥、化学肥料、农药等会随降雨进入周围的地表水系中,进而严重污染水体,危害水中的动植物资源,土壤气候、地质水文条件等也和此类污染存在紧密的关联。在防治这种污染情况时,要根据污染特点以及各类环境影响因素、人为因素等建立完善的指标体系,然后以此为根据形成污染防治措施。分析了小流域面污染的指标体系内容,并且制定了具体的污染指标监测方法。

Surface pollution in small watersheds is mainly aimed at the pollution of surface water system caused by agricultural production activities.Organic fertilizers,chemical fertilizers,pesticides,etc.used in agricultural production will enter the surrounding surface water system with rainfall,and then seriously pollute the water body and endanger the water.Animal and plant resources,suddenness,climate,geological and hydrological conditions,etc.are also closely related to this type of pollution.In the prevention and control of this kind of pollution,it is necessary to establish a complete indicator system based on the characteristics of pollution,various environmental influencing factors,and human factors,and then form pollution prevention and control measures based on this.Analyze the content of the indicator system of surface pollution in small watersheds,and formulate specific pollution indicator monitoring methods.
