Results showed that the topsoil structure of the CK treatment was dense with little porosity developed, and the soil microstructure was sandy granular fabric - granular fabric. In these treatments using chemical fertilizers only, the soil particles did not form soil structure with little porosity, and the soil microstructures in the N, NP or NPK treatment were observed as prophyropectic fabric-fine sand agglomerplasmic fabric, much better than the CK treatment. In those treatments receiving farm manure alone or farm manure plus chemical fertilizers, the quantity of groundmass increased obviously. The soil had a loosen structure, higher porosity, enriched animal and plant residua, iron-manganese nodules and humus, and more micro-aggregates developed. The soil microstructure of the MNPK treatment was pectized-compacted takyric fabric-intertextic fabric, the best microstructure observed among all the treatments.

Results are as following:The causes of grassland desertification of Hulunbeir are the outcome of interaction of nature and the human beings. Among these reasons, the loose soil texture, which was formed in the fluviolacustrine sediment during Quaternary, establish the physical ground, and the drought and wind is the natural force of grassland desertification. And then over-cutting forest, over-grazing grassland, imbalance of resource utilization and estrepement reduce the coverage of vegetation, therefore provide necessary conditions for the grassland desertification.

The results indicate that:(1)Compare with the comparion, the soil physics character are improved after vegetation restortion , the soil unit weight in cyclobalanopsis glauca, Pinus elliottii, Robinia pseudoacacia , mixed forest and fire slash shrub separatly are 1.525g/cm~3, 1.426 g/cm~3, 1.625 g/cm~3, 1.482 g/cm~3, 1.423 g/cm~3. We can find the soil unit weight in other forest all bigger than the comparion (1.580 g/cm~3) except Robinia pseudoacacia .All these mean forest soil is looser and better capacity for aerated and dank.
