| 摘 要： | 应用MODIS数据对2000—2009年植被变化情况及其与气温、降水量进行相关分析。2007年年均气温最高,降水最少,NDVI最大值和生长季平均值最低;在降水量最大的2003年NDVI最大值和生长季平均值最高。全生长季中气温和降水量与NDVI值具有显著或极显著相关,相对于气温、降水量对NDVI值影响更大;前一个月的气温和降水量对NDVI值的影响最大,植被对气象因子的响应具有时滞性。 |

| Abstract: | Using MODIS data to make analysis both on the changes in vegetation cover and its relationship with air temperature and precipitation in the year of 2000 to 2009.In the year of 2007, the average annual temperature reached the highest value and the precipitation reached the lowest one,meanwhile, the maximum of NDVI and the growing season average got the lowest value in 200？.Both of the maximum of NDVI and the growing season average reached the highest value in the year of 2003 when the precipitation was the highest one.During the whole growing season, the temperature and precipitation significantly related to the NDVI data. Compared to temperature, precipitation takes a greater impact on NDVI.Temperature and precipitation of the previous month makes the greatest influence on NDVI,the response of vegetation to meteorological factors has the time la,,. |
