Abstract: The area of the intermontane basins in the Xuefeng Mountain region is 4,000 km2. These basins are the most favourable area for agriculture in the mountainous region. Unfortunately, in each basin the eco-environment has gradually worsened because of the irrational utilization of natural resources. A rational model of agro-ecologic- economic system of intermontane basin must be formed so as to exploit and utilize rationally the natural resources. The intermontane basins may be divided into 3 ecologic belts of agriculture. Here are some ecologic-economic problems in the development: The resources of the outer mountains lie waste, but the valley basins in centre are over-development; the low mountains and hillocks are cultivated for dry crops so that the water and soil losses are serious and the natural disasters are frequent. Therefore, the agro-economic, agro-biologic and eco-environmental subsystems form a complete agro-ecologic-economic system of intermontane basins. Developing rationally the resources of these basins according to the local conditions, the system exports commodities to the society.
