Abstract

The invention belongs to the technical field of researching of an ecological system and provides a method for constructing a comprehensive control system for small-watershed surface source pollution. The method comprises the following steps of: firstly, carrying out remote sensing monitoring on water loss and soil erosion; then carrying out field positioning observation and manually-simulated rainfall; analyzing radial water loss and soil erosion of different land utilization types and an output rate of surface source pollutants including nitrogen, phosphorus and the like through the field positioning observation and the manually-simulated rainfall; calculating a nitrogen and phosphorus source surface pollution load strength and partitioning; carrying out control technology configuration and biological measure benefit monitoring on the surface source pollution which takes the water loss and soil erosion as a carrier; and finally, establishing the comprehensive control system of the small-watershed surface source pollution. The invention provides main measures needing to be adopted and provides evidences for guaranteeing the safety of a main water source land and planning work for supporting water and soil maintenance of a drainage basin, therefore, the method has stronger popularization and application values.

Description

technical field [0001] The invention belongs to the technical field of ecological system research, and in particular relates to a method for constructing a comprehensive prevention and control system for non-point source pollution in small watersheds. Background technique [0002] The soil in the small watershed with gentle slopes and hills on granite is loose, the sand content is high, and the soil water retention performance is poor; the land use types include farmland, orchard, and poplar forest, and the farmland is mainly planted with peanuts, sweet potatoes, and yellow tobacco. trees; farmland has been plowed and cultivated along slopes year after year, and farmers often weed orchards and terraced fields. The stability and erosion resistance of the surface soil is low, which makes soil erosion very serious in granite mountainous hills, and nitrogen and phosphorus in the soil are easy to deplete. Sediment loss with runoff, coupled with excessive application of chemical f...
