      abstract = {Through a series of exploration based on PSR framework  model, for the purpose of building a suitable Chongqing  agricultural non-point source pollution evaluation index  system model framework, combined with the presence of  Chongqing specific agro-environmental issues, we build a  agricultural non-point source pollution assessment index  system, and then study the agricultural system pressure,  agro-environmental status and human response in total 3  major categories, develope an agricultural non-point source  pollution evaluation index consisting of 3 criteria  indicators and 19 indicators. As can be seen from the  analysis, pressures and responses tend to increase and  decrease linearly, state and complex have large  fluctuations, and their fluctuations are similar mainly due  to the elimination of pressures and impact, increasing the  impact for agricultural non-point source pollution.},
