History of Soil Erosion Evolution in China

By taking the water source of Binxian County, Heilongjiang Province, the Erlong reservoir, as an example, the condition, process, mechanism, and transport way of non-point source pollution were investigated. The influences of fertilizer, pesticides, utilization and management of agricultural biomass waste, and soll erosion on the water source were analyzed. To achieve the human-water harmony, source of pollution and its transport way, capacity of ecological restoration, management of agricultural biomass waste in village, control of soil erosion, and the rehabilitation along the river corridor should be taken into consideration so as to control the non-point source pollution.
