摘要
以2000年LandsatTM图像和2004年中巴资源2号卫星(CBERS-2)遥感图像为基本数据源,利用遥感与GIS技术对山东省植被覆盖现状及其动态变化进行监测,建立山东省植被覆盖遥感监测数据库,通过空间分析、数量变化分析、区域差异分析、流失流向分析,对山东省2000-2004年植被覆盖的时空变化进行定量研究。结果表明:2004年山东省植被覆盖面积占全省土地总面积的15.28%,山地丘陵区为其集中分布区。2000-2004年山东省植被覆盖总的变化趋势是减少的,但速度缓慢,植被覆盖变化区域差异明显,植被覆盖的增加主要来源于耕地,植被覆盖的减少主要流向于耕地、水域、城乡居民点和工矿用地。
Based on the Landsat TM imagine in 2000 and the CBERS-2 imagine in 2004,the status and dynamic variation of the vegetational cover in Shandong were monitored with RS and GIS technique. The remote sensing monitoring database of vegetational cover was established and the spatial-temporal feature of vegetational cover was analyzed by the methods of spatial analysis,quantity change analysis,region variance analysis and loss and flow analysis. The result shows that：the area of vegetational cover of Shandong Province was 15.28% of the total land area in 2004,the hilly region is the centralized distribution. The trend of change on vegetational cover is decreasing, the rate of degradation is slowness and the regional difference was obvious. The increase of vegetational cover is root in reduce of farmland,and which is turn to farmland,water region and residential area.
