| Abstract: | The growth of vegetation is affected by water/thermal conditions and,in a certain area,there exists a definite relationship between the water/thermal condition and the climate.It is hence very important to probe into the influence of water/thermal conditions on vegetation growth.In this paper,the remote sensing data different from data based on the points in the traditional method were used to do research work in Qinghai-Tibet Plateau.The authors analyzed the remote sensing data of 2003 and the results show that in the time domain,there exists a good correlation between LAI and temperature,soil moisture,and precipitation,and in the spatial domain,the correlation in most of the area is also good.Nevertheless,there also exist some weak and negative correlations,which are also discussed in this paper. |
