| Abstract: | In this study,based on the RS and GIS systems,AVHRR/NDVI data of 8 km resolution and meteorological data were used to analyze NDVI,annual precipitation,and temperature change rates by pixel from 1981 to 2000.In addition,the correlation between NDVI,annual rainfall,and annual average air temperature were calculated.The results showed that annual precipitation increased in the northern and southern areas of the Hai Basin from 1981 to 2000 while declining in the central area,with a range of-80 to 80 mm/10 a('a... |
