基于AHP的柳州市彩叶植物景观评价体系构建

Construction of the Landscape Evaluation System for Colored Leaf Plants in Liuzhou City Based on AHP

以柳州市彩叶植物为研究对象,运用层次分析法(AHP)确定彩叶植物景观评价体系。从柳州市彩叶植物景观的生态功能、景观功能、服务功能3方面构建彩叶植物景观评价体系,选取了与周围环境的协调性、季相变化、彩叶植物的比例等13个评价指标进行了评价。结果表明:准则层权重值分别为:景观功能B1(0.643)、生态功能B2(0.283)、服务功能B3(0.074)。通过评价结果得出对彩叶植物景观的影响最重的是景观功能,其次是生态功能。而指标层中,权重值前3的是植物色彩多样性(0.349)、彩叶植物的比例(0.150)和植物的适生性(0.132)。12个公园的样地景观的评分结果值均在3.0~4.5分之间,表明柳州市彩叶植物景观总体良好。通过评价结果为园林设计者推荐了5种优秀的植物配置,为柳州市的植物彩化提供参考。

Taking colored leaf plants in Liuzhou City as the research object,the Analytic Hierarchy Process(AHP)was used to determine the landscape evaluation system for colored leaf plants.A color leaf plant landscape evaluation system was constructed from three aspects of ecological functions,landscape functions,and service functions of the color leaf plant landscape in Liuzhou City.Thirteen evaluation indicators were selected for evaluation,including coordination with the surrounding environment,seasonal changes,and the proportion of color leaf plants.The results show that the weight values at the criterion level are:landscape functions B1(0.643),ecological functions B2(0.283),and service functions B3(0.074).According to the evaluation results,the landscape function has the most significant impact on the color leaf plant landscape,followed by ecological functions.And in the indicator layer,the top three weight values are plant color diversity(0.349),proportion of colored leaf plants(0.150),and plant adaptability(0.132).The scoring results of the landscape samples from 12 parks are all between 3.0~4.5 points,indicating that the overall color leaf plant landscape in Liuzhou City is good.Through the evaluation results,5 excellent plant configurations were recommended for landscape designers,taking the colorization of Liuzhou City to a higher level.
