ON COUNTERMEASURES FOR THE CONTROL OF NON -POINT SOURCE POLLUTION IN MOUNTAINOUS REGIONS

Taking into consideration the topographic characteristics of Chongqing and the factors influencing the occurrence of agricultural nonpoint source pollution in hilly or mountainous regions,this paper puts forward measures for controlling agricultural non-point source pollution in such regions.On the one hand,plans for preventing agricultural source pollution are to be made based on the natural environment conditions and the level of local social and economic development.On the other hand,eco-agriculture needs to be developed in such a way that a positive cycle for substances and energy inside the ecosystem may be formed.The sources of agricultural non-point source pollution,such as fertilizer,pesticide,crop straw,livestock manure and rural domestic waste,should be well managed.
