This research is conducted in the Loess Plateau in the northwestern part of China In our research, desertification will occur in case that "Climatic Production Factors" such as the climatic primary production of plants exceeds "Inhibition Factors" such as the soil moisture and pasturage.Three groups are organized in our project members they are "Digital mesh data group", "Agronomy group" and "Pasturage group" and they are took part in our project as follows :1) "Digital mesh data group" : It made mesh data of "climatic production factors" and investigated at the research field if the mesh data showed improper results.2) "Agronomy group" : It developed models for "inhibition factors" for mesh data and the models are applied to mesh data. It also investigated at the research field if the mesh data showed improper results.3) "Pasturage group" : It checked the products of "Digital mesh data group" and compared its results with pasturage intensity.Finally, we made the hazard map to the Loess plateau with its resolution of 10km and it will contribute to protection of desertification for the Loess plateau.
