The investigation for degenerate grassland of "Degenerated Meadow" in San jiang yuan Nature Reserve

LIU Xiao-lin (Provincial Geomatic Information Centre of Qinghai,Xining 810008,China)  
In this paper,according to the classificatory criteriafor degenerate grassland of "Degenerated Meadow",use remote image data and its characteristic from China-Brasil satellite、land American satellite TM、SPOT satellite as the information source,use GPS data as the accurate positioning method in space,and use GIS as the method of space analysis,make an basic remote investigation for degenerate grassland of "Degenerated Meadow" in San jiang yuan area Nature Reserve,get basic data as thematic map,abstract and make out the images for various rank of distributed area、distributed scope、area of degenerate grassland of "Degenerated Meadow" in San jiang yuan area,establish the data base and the geographical information system of degenerate grassland of "black earth sands"in San jiang yuan area.
