THE LAND USE CLASSIFICATION USING NOAA METEOROLOGICAL SATELLITE DATA FOR THE HEDONG REGION OF GANSU PROVINCE

根据不同植被群落植被指数的时空变化特点，利用１９９１—１９９３年ＮＯＡＡ气象卫星ＡＶＨＲＲ资料对３２５°—３８０°Ｎ，１００５°—１０９０°Ｅ范围内的土地覆盖状况进行了分类。

In this paper,the land use in the region of 32 5 ° 38 0 ° N,100 5 ° 109 0 ° E is classified according to the vegetation index difference in time and space of various vegetations by using NOAA/AVHRR data from 1992 to 1993 The annual variation characteristics of vegetation index of different land use are discussed according to classified results
