摘要: 公路建设与其周边生态景观存在不和谐的问题,公路生态景观的评价分析、恢复与建设越来越成为重要的课题。针对景观评价问题,本文提出了运用3S(remote sensing、geography information system、global positioning system)技术构建生态景观评价系统,并应用层次分析法对公路生态景观进行评价。该评价方法将公路生态景观分解为3个层次,经过矩阵一致性检验的判断确定了评价要素的权重,该权重与生态景观要素得分运算后得到生态景观评价结果。运用该系统对全桂公路进行了生态景观评价测试,结果表明,评价与专家组在当地调查情况基本一致,证明了该方法的有效性及系统设计的可行性。

Abstract: To harmonize the construction of highway and its peripheral ecological landscape,this paper designed an assessment system of highway ecological landscape by using 3S technology and analytic hierarchy process.The highway ecological landscape was disintegrated into 3 hierarchies,and the weights of assessment elements were ascertained through verifying matrix accordance.The application of this system in assessing the ecological landscape around Quangui highway showed that the assessment results were coincided with investigation results,which proved the effectiveness of the analytic hierarchy process.
