基于AHP-GIS空间分析法的龙胜龙脊古壮寨景观评价

Landscape Evaluation of Longji Ancient Zhuang Village in Longsheng Based on AHP-GIS Spatial Analysis

以龙胜龙脊古壮寨为研究对象,采用层次分析法(AHP法)建立景观评价体系,运用GIS空间分析法对古壮寨景观进行景观等级划分,并制定分级建设保护策略。结果表明:龙胜龙脊古壮寨区域景观差异较明显,其中Ⅰ级、Ⅲ级与Ⅴ级景观分别占研究区域总面积的0.78%、0.12%、0.10%。无Ⅱ、Ⅳ级,表明龙胜龙脊古壮寨景观总体较好。基于以上评价结果,将龙脊古壮寨规划为风貌协调区、开发建设区和建设控制区。风貌协调区应维持对现有景观的保护;开发建设区应重点加强对生态环境的保护;建设控制区应在不影响原有风貌的前提下进行景观建设。该评价对龙胜龙脊古壮寨的发展与保护决策具有科学辅助意义。

This paper was aimed to establish a landscape evaluation system for Longji Ancient Zhuang Village in Longsheng,based on AHP（analytic hierarchy process）.And by using GIS spatial analysis,this paper graded and made conservation strategies for ancient village.The results showed that an obvious difference in Longji Ancient Zhuang village in Longsheng,where the areas of level ofⅠ,ⅢandⅤrepresented 0.78%,0.12%and 0.10%in total area,respectively.The areas of level ofⅡ,Ⅳ was zero.The result indicated the quality of landscape in Longji Ancient Zhuang village in Longsheng was preferable a whole.Based on the result,the research divided these three parts into coordinate area,developing area and constructing area.The existing landscape should be conserved in coordinated area.The protection of ecological environment should be strengthen in developing area.The construction was allowed to proceeded without destroying the original environment.It aimed to confirm the landscape evaluation in studying scope and so as to push application of ancient village planning.
