The Scheme and Effectiveness of Four Functions as a Model in Courtyard

It has been described that background, practical values and theory basis of the four functions as a model. When we designed the scheme of the mode, we considered some factors such as market demand, technologic level, resource explorative potentiality and the life and production habitation, fundamental insulation condition. Meanwhile, we followed the principle of resource sustained utility and improved the coordinated development in the rural area economic and system multipurpose. It also set forth our views of the basic content of the technologic mode, We evaluated the effectiveness of the economic and environment. It showed that the technologic mode improved the quality of agro-products and the production structure, realized the purpose of the raise of the resources and labor productivity. This mode is the courtyard agro-ecology engineering mode. It may be concluded that the mode was likely to be popularized in the north of China.
