Abstract:
Slop land resource is an important part of land resource in China and its utilization and conservation deeply affect the stability of environment. It will playan important role on soil land water conservation and improvement of mountain area eco-environment for cultivated slop land to be returned to forest for instance: agroforestry method, contour hedgerow technique, plant barrier, terraced field and so on up till now. The models of agroforestry and terraced field are use extensile, but comparing with other methods of slop land utilization, contour hedgerow technique cost is less and its effect in soil water conservation and soil fertility sustaining is terrific. So it is necessary to be applied and popularized.
