A Study on Spatial Distribution of Sinking Sandy Land by Using the Methods of Remote Sensing of Man-Computer Interactive Interpretation and Supervised Classification — Taking West Ujimqin Banner as an Example

Article Preview

Abstract:

the excessive exploration and utilization of land is the main cause of desertification. Utilizing and exploring sinking sandy land has been accelerating the process of desertification. The data sources for our research are mainly based on remote sensing data, and these data have been processed through a series of correcting and enhancing measures. By using these data and the results of some field investigations, the image features have been analyzed and then the interpretation keys of sinking sandy land are established. The distribution of sinking sandy land has been clarified by using the following two remote sensing methods: Man-Computer Interactive Interpretation classification and Supervised Classification. A comparison between the precision of these two methods has been done. The research is trying to find the most suitable method for the study of the spatial distribution of the sinking sandy land in West Ujimqin Banner and also trying to lay a scientific and theoretical foundation for determining the spatial distribution of the sinking sandy land in Inner Mongolia.
