摘要
利用RS、GIS空间信息技术,基于Landsat TM/ETM+、CBERS-02B CCD遥感影像数据专题解译,对西霞院水库建设前后区域景观格局动态变化进行了分析,探讨了景观格局变化的驱动力。结果表明:区域景观格局变化是自然环境条件和人为因素相互作用、共同约束的结果,其中水利工程建设是景观格局变化的直接驱动力,人口增加和城镇化以及自然因子对于区域景观格局变化也起到一定促进作用。
With RS and GIS spatial information technology, the dynamic change of the regional landscape pattern of Xixiayuan Reservoir before and after the construction is analyzed based on the specific interpretation of the remote sensing image data of Landsat TM/ETM ＋ , CBERS-02B CCD, and then the driving forces on the change of the landscape pattern are discussed. The results show that the change of the regional landscape pattern is just the result from the interaction between the natural environ- mental condition and the human factors as well as their common restriction concerned; in which the construction of the water re- sources project is the direct driving force on the change of the landscape pattern, furthermore, the population growth, the urbanization and the relevant natural factors play certain promoting roles on the change as well.
