苏州城郊山地景观生态遥感研究

在1986和1998年遥感影像研究的基础上，利用2002年的遥感影像再次对苏州城郊低山丘陵的植被覆盖进行了判读分析。结果显示1986至1998年新增裸地20km^2，而1998至2002年新出现裸地降至1．77km^2。近几年苏州山地植被景观受破坏程度明显降低，这主要得益于苏州市“禁止开山采石条例”的制定和有效执行。与此同时，近年来山地范围村镇建设、房地产开发以及工程建设对山地植被景观包括历史人文景观的破坏变得突出。苏州山地植被景观研究、保护与管理工作还有待加强和完善，否则与吴文化和苏州古城根基密切相关的苏州城郊山地景观仍有遭受破坏和消失的危险。

Ecological Remote Sensing Study on Mountainous Landscape in the Suburbs of Suzhou

Based on the study of remote sensing images in 1986 and 1998,this paper analyzes the vegetation covering of the hills in the suburbs of Suzhou by making use of remote sensing images in 2002. The result shows that the bare land was 20km2 from 1986 to 1998 and that newly increased bare land dropped to 1.77km2 from 1998 to 2002. The destruction of vegetation has apparently declined these years in Suzhou, attributable to the establishment and effective enforcement of the Rule of Prohibition of Mountain-Excavating and Quarrying by Suzhou Government in 2000. The vegetation landscape has been better protected since 2000,but bare lands where were excavated in the past time have not been healed or recovered by vegetation. Meanwhile, the vegetation and culture landscape in these areas are still nibbled by such activities as town and village construction,real estate and engineering building. The study, protection and management of mountainous vegetation landscape of Suzhou need enhancing and improving, for these beautiful landscapes around the city which bred Suzhou city and Wu culture are still threatened by human negligent activities.
