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.展开更多

A campaign for construction of eco county has been developed all over China since the 1990s. It is aimed to enhance sustainable development capacity of the county by establishing ecologically sound production system and management mechanism through eco engineering, eco planning and eco management. It is a complicated systems engineering and a combination of multi disciplinary and needs the most extensive participation of decision makers, technicians, and farmers. Construction of eco county consists of many important works such as survey, systems diagnosis, planning, demonstration, implementation and assessment. In this paper, we will try to summarize the current status, main models in different regions, procedure of construction, and introduce the eco agriculture county construction in detail by taking Dazu County of Sichuan Province as an example.展开更多
