文摘内容 Temporal and spatial response characteristics of vegetation NDVI to the variation of temperature and precipitation in the whole year,spring,summer and autumn was analyzed from April 1998 to March 2008 based on the SPOT VGT-NDVI data and daily temperature and precipitation data from 205 meteorological stations in eastern China.The results indicate that as a whole,the response of vegetation NDVI to the variation of temperature is more pronounced than that of precipitation in eastern China.Vegetation NDVI maximally responds to the variation of temperature with a lag of about 10 days,and it maximally responds to the variation of precipitation with a lag of about 30 days.The response of vegetation NDVI to temperature and precipitation is most pronounced in autumn,and has the longest lag in summer.Spatially,the maximum response of vegetation NDVI to the variation of temperature is more pronounced in the northern and middle parts than in the southern part of eastern China.The maximum response of vegetation NDVI to the variation of precipitation is more pronounced in the northern part than in the middle and southern parts of eastern China.The response of vegetation NDVI to the variation of temperature has longer lag in the northern and southern parts than in the middle part of eastern China.The response of vegetation NDVI to the variation of precipitation has the longest lag in the southern part,and the shortest lag in the northern part of eastern China.The response of vegetation NDVI to the variation of temperature and precipitation in eastern China is mainly consistent with other results,but the lag time of vegetation NDVI to the variation of temperature and precipitation has some differences with those results of the monsoon region of eastern China.
