基于AHP法的环巢湖地区景观美学评价研究

Research on Landscape Aesthetics of Chaohu Lake-round Region Based on AHP

以环巢湖地区为研究范围,以大数据分析获取的该区域内公园景区POI数据为研究对象,采用层次分析法建立景观美学评价指标体系,利用GIS技术进行空间统计与分析,完成对代表环巢湖地区景观美学质量热点区域评价,总结环巢湖地区景观存在问题并提出相应提升策略,以期为环巢湖湿地旅游区景观资源科学保护、开发和利用提供支撑。结果表明:(1)在指标层各指标权重中,占比前3的指标为:色彩丰富度0.3013,季相变化0.1725,地物形态变化0.1427;(2)经ArcGIS分析得出环巢湖热点区域Ⅴ级、Ⅳ级和Ⅱ级热点区域数量占比为12.5%,Ⅲ级热点区域占比为37.5%,Ⅰ级占比为25%,环巢湖地区热点区域景观美学质量为中上水平。

This paper takes the Chaohu Lake-round Region as the research scope,uses the Point of Interest(POI)data of the park scenic spots in the area obtained by big data analysis technology as the research object,adopts the analytic hierarchy process(AHP)and Matrix Laboratory software to establish a landscape aesthetics evaluation index system,using GIS to carry out spatial statistics and analysis,completed the evaluation of hot spots representing the landscape aesthetic quality of the area around Chaohu Lake.The existing problems of the landscape around Chaohu lake were summarized and the corresponding improvement strategies were put forward in order to provide support for the scientific protection,development and utilization of the landscape resources in the tourist leisure area around Chaohu lake.The results show that among all index weights of index layer,the first three indicators accounted for 0.3013 of color richness,0.1725 of seasonal changes and 0.1427 of terrain morphology changes.Secondly,through the analysis of data superposition operation by ArcGIS,it is concluded that the number ofⅤ-level,Ⅳ-level andⅡ-level hot spot areas around Chaohu Lake accounts for 12.5%,Ⅲ-level hot spot areas for 37.5%,Ⅰ-level for 25%,and the landscape aesthetic quality of hot spot areas around Chaohu Lake is at the middle and upper level.
