摘　　要：随着城市建设的日新月异,利用NDVI进行城市绿化动态变化的监测已经成为一个行之有效的方法.本文选择我国CBERS自主遥感数据,通过北京城区2001-2007年多时序夏季NDVI专题信息提取,分析了奥运建设前后植被覆被时空分布及变化特征,并初步分析了NDVI演化驱动机制,认为北京城区绿地变化存在3个典型阶段,即发展停滞期、发展高峰期和发展平缓期.研究结果对北京市宜住城市建设和规划管理具有一定参考价值.With the rapid urban construction, it has become an effective way to monitor the urban greenland change using the remote sensing imageries. In this paper, the CBERS data, China＇s own remote sensing imageries, were selected to extract the thematic information of multi-temporal NDVI of Beijing City in the summer from 2001 to 2007. Followed, the temporal and spatial distribution of vegetation cover and changing characteristics were analyzed, and the driven mechanisms of NDVI evolution were discussed before and after Olympic Games construction. The result showed that there were three typical stages during the changes of Beijing City Greenland, including such there periods as stagnation development, high-speed development and slow development. The results of the study can provide some reference to Beijing city construction and planning managements.
