Agricultural product trading website is not only an important way to realize the agriculture informatization, but also the main manifestation of the agricultural informatization. Based on the preliminary understanding of the content and characteristics of China's agricultural product trading website, the paper builds a scientific evaluation indicator system and evaluates 50 typical agricultural product trading websites objectively by using classification and grading method. The results show that the overall construction level of China's agricultural product trading websites is general, and there are obvious differences between regions; the lack of website commercial function and the lag of informatization are the main factors restricting the development of agricultural product trading websites.

Through a series of exploration based on PR framework model, for the purpose of building a suitable Chongqing agricultural nonpoint 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, developed 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.
