Study on Regionalization of Land Ecological Function and Environment-friendly Land-use Patterns in Poverty Agriculture Areas——As an Example of Yanshou County

Land was not only an important natural resource,but also a basic element of the ecological environment.To a large extent land-use determined the pressure imposed on the environment.Facing the dual pressure of economic and ecological development,it was more necessary for the poverty agriculture areas to do the ecological function zoning and look for reasonable land-use patterns.Then the development pattern ofpollution first,treatment later could be avoided in these areas.In this paper,Yanshou County,as a typical agricultural county was taken for an example.Considering fully local natural and economic conditions,this paper divided it into three zones of ecological functions:the central agricultural district in the plain of Mayan River,soil and water conservation and agricultural district in front of the hills,forestry sustainable land-use district in north and south hilly areas.According to the characteristics of land resources,this paper discussed the environment-friendly land-use patterns in every district and proposes regional governing measures and landuse direction.
