The application of this technology could effectively assure that rainfall abundantly infiltrate soil of purple soil slopping farmland, decrease non-point pollution and maintain productivity of land on slopping farmland.

该技术的应用可有效地保证紫色土坡地土壤对降雨的充分入渗，减少面源污染，保持坡耕地的土地生产力。

Most of the academic research just rests on the superficial description of the total pollution, so that people are unable to make out the trued of the village pollution of reason, especially, causes of Non-point Pollution of villages, which has not been taken seriously.

学术研究也大多停留在总体的污染情况描述，以至于无法真正理解造成农村环境污染的真实原因，尤其是村民现实层面的面源污染问题，我国环境社会学还没有深入的研究。

Among non-point source pollutions, the agricultural non-point pollution source is the biggest source.
