The Review of Current Distribution of Vegetation Resources in Yunnan-Guizhou Plateau and the Mechanism Research of Its Effects on Rocky Desertification Process
Yunnan-Guizhou Plateau is the core area of the rocky desertification in the Chinese southwest karst regions. Previous studies are very limited to describe the process of rocky desertification quantitatively. The vegetation resources are applied as the key indicators to quantitatively study the degree of rocky desertification by many researchers. With the remote sensing datasets, previous methods are not competent to distinguish the detailed information of vegetation type, coverage and patch
... erage and patch fragmentation on a large scale. Our previous researches show that the technology of unmanned aerial vehicle and the estimation software of fraction vegetation coverages and patches could be accurately and rapidly to exploit vegetation resource information. In this project, current distribution of vegetation resources in Yunnan-Guizhou Plateau will be clarified to reveal the influence mechanism of the rocky desertification. The control factors of rocky desertification distribution and the driving reasons of its dynamic changes will be explained by the data of terrain, climate, population, economics and policy. In this way, current distribution of vegetation resources in Yunnan-Guizhou Plateau will be provided, especially the grassland resources will be updated. The finding of this research may have significant implications for resolving rocky desertification. Furthermore, the results of this study will be the background information for the programs of restoring ecological environment and enriching local people in Yunnan-Guizhou Plateau.
