中文摘要：

以长江中下游为研究区，利用1998--2008年归一化植被指数（NDVI）和1951-2011年基准气象观测资料，借助区域气候模型RegCM3和MODIS遥感，分析测站“点”上植被“覆盖量”、区域“面”上植被“覆盖类型”与气候变化的关系。结果表明：（1）气温、NDVI值有逐年上升的趋势，降水量变化不大。年纪尺度NDVI与气温呈较强正相关，与降水呈弱负相关。（2）在选定的3个植被下垫面中，以农田植被覆盖为主的长三角丘岗城乡交错区年增温最弱。春夏秋季增温趋势从大到小为：赣浙皖山地森林区〉鄂皖低山丘陵混合林区〉长三角丘岗城乡交错区，冬季则完全相反。春夏秋季节农田植被区的降水量随时间增加显著，森林区的降水量则显著减少，冬季的降水量都有所增加。

英文摘要：

With the middle and lower reaches of Yangtze River as survey region, under the support of observations from normalized differential vegetation index （NDVI） during years from 1998 to 2008 and benchmark weather stations from 1951 to 2011, using regional climate model RegCM3 and remote sensing data from MODIS, the relationship between veg- etation condition and climate change had been analyzed, in perspectives of point, vegetation coverage and area, vegetation cover type respectively. The results showed that： （ 1 ） NDVI value and air temperature had the trend of as- cending, precipitation mainly remained unchanged. From the point of annual time scale the relationship between NDVI and temperature appeared stronger positive correlation, and showed a weak negative correlation with precipitation. （2） In the selected three underlying surfaces, the trend of increasing temperature in staggered area of hills and urban and rural in Yangtze River delta region was the weakest, whose majority vegetation cover was farmland. In spring, sum- mer and fall season, the trend looks like, forest area of Zhejiang, Jiangxi, Anhui mountain 〉 mixed forest area in low hills of Anhui 〉 staggered area of hills and urban and rural in Yangtze River delta region. Conditions in winter were the opposite. For the precipitation analysis, in the season of spring, summer and fall, the value in farm land areas increased significantly, and forest precipitation decreased significantly; in winter, all values in three areas increased.
