The criteria for the construction of an eco agricultural county in China were suggested. The criteria should coordinate social, economic, and environmental effects together. At first, it emphasizes on the social effect input into the system, which includes population control, cultural, scientific, and moral education, technical training and so on. Secondly, economic criteria are mainly those of the increase of gross national product(GNP) and income per capita every year. Finally, the technical criteria consist of not only the grain yield, commodity percentage of the agricultural product, cultivated output/input, animal husbandry production value/total agricultural production value and other agricultural criteria, but also environmental criteria, such as the percentage of forest and grass cover, degenerated land under control, recycling of organic waste, recommended fertilization, integrated pest management, treatment of discharged wastes and others. In an eco agricultural system, the realization of these criteria by three different development steps were recommended too.
