摘要
城市植被的空间分布是城市生态环境质量变化的重要标志,对其进行研究,可为城市规划与建设提供决策支持。为研究珠海市植被覆盖的动态变化情况,利用两期Landsat TM/OLI影像,从数量变化、空间分布和时空变化3个方面探讨了研究区的城市植被覆盖动态变化。研究结果表明:(1)珠海市植被覆盖面积在2009~2014年有所减少;(2)珠海市大面积的植被覆盖主要由山体构成;(3)2009~2014年植被覆盖减少,主要转化为建设用地,特别是在南湾、横琴和西区尤为明显,与近年来中心城区开发强度趋于饱和、新增建设用地主要集中于此有关。
The spatial distribution of urban vegetation is an important symbol of the changes of urban ecological environment quality. Studying the spatial distribution of urban vegetation cover and its changes can provide a decision support for urban planning and construction. In order to study the dynamic changes of vegetation cover in Zhuhai City, we used the satellite images of Landsat TM/OLI in two different times to study the changes of urban vegetation cover from three aspects, such as quantitative change, spatial distribution and spatiotemporal change. The results show that(1) the area of vegetation cover in Zhuhai City has decreased from 2009 to 2014.(2) The large area of Zhuhai City is mainlycomposed of several mountains.(3) The lost vegetation cover area mainly converted into construction land, and it is obvious especially in Nanwan, Hengqin and western area in Zhuhai, because the intensity of development in urban area tends to be saturated and the latest construction land mainly concentrates in those areas.
