On Response of Temporal Evolution of Vegetation Cover to Climate Change in Western Sichuan Alpine and Plateau Transition Zone

摘要: 植被是陆地生态系统的主体，被认为是人类环境评价和监测的重要参数，利用遥感技术来监测植被生长及其对气候因子的响应成为当前全球变化研究的热点之一。川西高山高原区是我国地势最高一级的青藏高原向川西南山地和四川盆地的过渡地带，属生态环境脆弱区，对全球气候变化敏感。基于 MODIS 植被产品及气温、降水站点数据对2001-2010年川西高山高原过渡带的气温和降水的年际变化、NDVI 的时空演变及其与气候因子的相关关系，较好的揭示了研究区的植被生长对气候因子变化的响应特点。研究结果表明：NDVI 与降水量和气温均呈正相关关系。温度是春季植被生长的主要影响因素，降水量是秋季植被生长的主要影响因素。

Abstract: Vegetation,the main terrestrial ecosystems,is considered as an important parameter in evalua-ting and monitoring the human environment.Based on remote sensing technology to monitor vegetation growth,its response to climate factors has become one of the hot spots of global change research.Western Sichuan Alpine and Plateau is the zone of transition from the Qinghai-Tibet Plateau,the highest terrain in China,to the mountainous areas in Southwestern Sichuan and Sichuan Basin.It is an eco-environmental vulnerable area that is sensitive to global climate change.This paper,which is based on the MODIS vege-tation products and the meteorological data that includes air temperature and precipitation,by analyzing the correlation of annual variations of air temperature and precipitation,the temporal and spatial change of NDVI and the relationship between NDVI and climatic factors in Western Sichuan Alpine and Plateau dur-ing 2001 - 2010,is relatively good to reveal the response characteristics between vegetation and climate change factor in the study area.The results show that NDVI is positive correlated to precipitation and tem-perature,and that the vegetation growth in spring is mainly affected by temperature.In addition,precipi-tation is the main factor that affects the vegetation growth in autumn.
