内容 研究概要:Naiman Qi is located in the east edge of Horqin desert and recently affected by desertification. The desertification has progressed by overgrazing and overcutting and fixed sand dunes began to move again in this area. In this study, we intended to develop a monitoring method of desertification using Landsat data in order to understand how the desertification has progressed. We could define the desertified area using land use classification and following three indexes; vegetation [(TM4-TM3)/(TM4+TM3)], structure [(TM5-TM1)/(TM5+TM1)], and redness [(TM3-TM1)/(TM3+TM1)]. And we obtained yearly changes by superimposing desertified areas identified from data of different year.
