| Abstract: | Using digital method of remote sensing and geographical information system techniques, the database of sandy land of Qinghai Province in the middle period of 1990's was established. The database includes TM image database, graphical database and attributing database, and the time of TM image is mainly 1996(partly 1995). According to analyzing of database, the conclusion is as following: 1.There is as much as 4431749hm 2 sandy land, occupying 6.184% of the province's area. 2.Among 45 county units of the whole province, there are 19 county units distributing sandy land occupying 92.008% of the province's area. |
