江苏规划高速公路网生态环境影响研究

以RS和GIS为基础，运用遥感信息提取、编制自然保护专题系列图、系列图与规划高速公路网叠加、缓冲分析、统计分析等方法，对江苏省规划高速公路网生态环境影响进行分析。规划的5纵9横6联线路中的9条，对127个不同类型保护区中的9个有影响。11个过江通道中的5个对沿江饮用水源保护地有影响。规划高速公路占用的土地中76．74％是基本农田。跨越太湖的沪宁复线将加重梅梁湾、五里湖的水质富营养化。针对上述问题，从保护生态环境的角度提出6大对策：避绕生态保护对象，修改跨太湖线路方案，合理规划穿越山地丘陵区的线路，减少平原区生态破坏，调整过江通道与饮用水源地的交叉关系，保护白鳍豚生存环境安全。

Impacts of planned expressway network on eco-environment in Jiangsu

With the aid of the RS and GIS technology and remote-sensing information, a thematic series of nature conservation maps were plotted out. By overlaying the series of maps with the planned expressway network map for buffer analysis and statistical analysis, impacts of the planned expressway network on eco-environment were studied. Among the planned 5 vertical ,9 horizontal and 6 linking expressways ,9 will have certain impacts on 9 of the 127 different nature reserves, and among the 11 across the Yangtze River,5 will affect the drinking water reserves along the Yangtze River. About 76.74% of the land that is to be occupied by the planned expressways will be basic farmland. The expressways striding over the Taihu Lake will aggravate eutrophication of the Meiliang Bay and Wuli Lake. In response to the above-listed problems, six important strategies are proposed with a view of protecting the eco-environment.
