中文摘要：

植被作为表征陆地生态环境变化的指示器,其对气候变化的响应研究已成为当前全球变化领域的主要内容之一。基于1982—2012年归一化植被指数（NDVI）和同期观测温度和降水资料,分析了内蒙古地区植被对气候变化的响应。研究表明,1982—2012年,植被指数总体呈波动变化,且区域差异明显。从年际变化来看,植被受降水影响明显;年内变化上,气温对植被的作用明显。内蒙古不同区域植被对气候的响应方式不同,其中内蒙古东北部地区对气温和降水的响应无滞后时间,其余地区对气温和降水的滞后时间为1个月。

英文摘要：

Vegetation is known as an indicator of the terrestrial ecosystems response to climate change. In this paper,the GIMMS normalized difference vegetation index（NDVI）dataset and meteorological data（e.g.,air temperature and precipitation）from 1982 to2012 are employed to investigate the response of vegetation to climate change in Inner Mongolia. The results indicated that there was an evident correlation between the NDVI change and the climate change in Inner Mongolia from 1982 to 2012. The vegetation was significantly affected by precipitation. The response of growing season vegetation to climatic changes indicated that temperature,rather than precipitation,played a driving role on the vegetation ecological system. The regional responses of vegetation to climate change were different. There was no lag time between vegetation and temperature/precipitation basically in the northeast region of Inner Mongolia. However,lags about one month in responses in other regions..
