Hang im county lies in the south bank of the Yellow River, northwest of the Eerduosi plateau. It is the typical ecological
environment weak region,because of the bad effect ofthe natural and human elements, the land was degradated in large area. The
degradation wasoccured in different degree in almost all over the county. The type of the degradation was various, such as, the wind eroded sandification, the grassland degradation, loss of soil and watererosion and the soil secondary salinization. Among these, the wind eroded sandificatlon and thegrassland degradation were major. The important point of the
harnessing methord was deep adjusted the land use structure, set up the land use structure of the ecologic economic types, andon the basis of the land use direction and the important point of the harnessing, to divid area toharness. Make sure to protect the farmland make efforts to plant ecologic forest and grass,prevent wind and regularize sand,conserve water and soil. Strengthen the grassland construction, determine the qtlantity of the animal based on the grasslalld production,restore and raisethe grassland productive forces, make the grassland can be sustaining used.
