| 摘 要： | 利用中国东部SPOT VGT-NDVI数据和气象站点的日平均气温和降水资料,分析了1998-2007年中国东部植被NDVI在全年、春季、夏季和秋季对气温和降水变化的旬时空响应特征.结果表明,中国东部植被总体上对气温变化的响应大于降水,植被对气温变化的最大响应滞后1旬左右,对降水变化的最大响应滞后3旬左右.秋季植被NDVI对气温和降水变化响应最大,夏季NDVI对气温和降水响应的滞后期较长.在空间上,植被对气温变化的最大响应总体表现为北部和中部大于南部,对降水变化的最大响应表现为北部大于中部和南部.植被对气温变化最大响应的滞后期呈现出北部较长-中部短-南部最长的空间分布,对降水变化最大响应的滞后期则随着纬度降低由北到南逐渐延长. |

| Abstract: | This paper analyzed the temporal and spatial responses of vegetation NDVI to the variations of temperature and precipitation in each ten-day period in the whole year,spring,summer and autumn covering 1998 to 2007 based on the SPOT VGT-NDVI data and daily temperature and precipitation data from 205 meteorological stations in eastern China.The results indicate that on the whole,the response of vegetation NDVI to the variation of temperature is greater than to that of precipitation in eastern China.Vegetation ... |
