Desertification hazard map to the agricultural and pasture area of Huang He (the Yellow River)

本研究是在中国西北黄土高原地区进行的。在我们的研究中，当“气候生产因子”如植物的气候初级生产力超过“抑制因子”如土壤湿度和牧草量时，就会发生沙漠化。我们的项目成员组织了三个组，它们是“数字网格数据组”，“农学组”和“畜牧组”，他们参加我们的项目如下：1）“数字网格数据组”：它使“气候生产因素”的网格数据，并在研究领域调查，如果网格数据显示不正确的结果。它为网格数据开发了“抑制因子”模型，并将该模型应用于网格数据。（3）“畜牧业组”：对“数字网格数据组”产品进行检验，并与畜牧业强度进行对比，最终制作出分辨率为10km的黄土高原荒漠化危害图，为黄土高原荒漠化防治提供参考。

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.
