摘要
应用图像处理和地理信息系统软件 ,对苏州市 1 986年和 1 998年的卫星影像进行对比分析 ,发现市区西南部灵岩山等 58座低山丘陵的植被在 1 2年间面积减少了 2 0km2 。在此基础上 ,结合实地调查指出了植被减少的原因和由此可能在苏州旅游业、生态环境、城市发展等方面产生的影响 ,并强调对于发展迅速的苏州市 ,遥感监测在资源与环境管理上的重要作用。
Based on the software of image processing and geographic information system, the satellite images on Suzhou area in 1986 a nd 1998 have been interpreted. The results show that during 12 years the vegetat ion cover on the low mountains and hills in southwest Suzhou had been reduced 20 km^2. The relations between the vegetation reduction and human activities are p ointed out. Some problems on local tourism, local ecosystem and the city's susta inable development that are caused by the vegetation reduction are discussed. Me anwhile, it is emphasized that to a quickly developing city of Suzhou, remote se nsing monitor is a useful method in the city's land resources and environmental management.
