| 摘 要： | 为解决目前高速公路建设区域生态环境保护、恢复与重建等缺乏可靠的科学依据的问题,从高速公路建设区域生态环境特点出发,确定生态功能区划的依据和区划因子。对区域内生态敏感性和生态服务功能重要性分别进行单因子评价和综合评价,并在ArcView和SPSS软件支持下绘制各专题图。在此基础上,利用ArcGIS软件校正并数字化单要素专题图,调用聚类分析模块,结合自上而下顺序划分与自下而上逐级合并的区划方法,得到高速公路建设区域生态功能区划结果。以穿越秦岭生态保护区的西安-汉中高速公路户洋段为实例分析,将高速公路建设区域分为2个高级生态区,10个生态功能小区,其中户洋段高速公路跨越5个生态功能小区。
