基于AHP法的天津近郊农业观光园植物景观评价研究

Research on Plant Landscape Evaluation of Tianjin Agricultural Sightseeing Garden Based on AHP Method

为了提高农业观光园植物景观的质量,挖掘植物造景的价值,科学分析园区植物应用的优势与不足,本文采用层次分析法对天津近郊农业观光园植物景观进行综合评价,获得评价指标权重及重要性排序。结果表明:准则层权重值由高到低排序为美学功能(0.5396)>服务功能(0.2970)>生长状况(0.1634);因子评价层中整体观赏效果(0.2292)>科普教育性(0.1856)>层次丰富度(0.1449)>健康状况(0.1089)>色彩与季相变化(0.0843)>可停留性(0.0708)>养护管理(0.0545)>意境美(0.0513)>标志性(0.0405)>植物形态变化(0.0299)。最后根据植物景观综合评价指数分级标准将4个园区进行分级,万源龙顺庄园和水高庄园为Ⅰ级,名洋湖都市庄园为Ⅱ级,无暇生态园为Ⅲ级。天津市近郊农业观光园植物景观总体较好,在美学、生长状况和服务功能方面均有良好的综合质量。

In order to improve the quality of plant landscape in agricultural sightseeing garden,excavate the value of plant landscaping,and scientifically analyze the advantages and disadvantages of plant application in the park,this paper used analytic hierarchy process to comprehensively evaluate the plant landscape in Tianjin suburban agricultural sightseeing garden,and the weight of the evaluation indexes and their importance order were obtained.The results showed that the weight value of the criteria layer was from the highest to the lowest,which was aesthetic function(0.5396)>service function(0.2970)>growth status(0.1634);in the factor evaluation layer,the overall ornamental effect(0.2292)>popular science education(0.1856)>level richness(0.1449)>health status(0.1089)>color and seasonal change(0.0843)>retention(0.0708)>maintenance management(0.0545)>artistic conception beauty(0.0513)>landmark(0.0405)>plant morphological change(0.0299).Finally,according to the classification standard of the comprehensive evaluation index of plant landscape,the four parks were classified.Wanyuanlongshun Manor and Shuigao Manor belong to grade I;Mingyanghu Urban Park belongs to grade II;Wuxia Ecological Park belongs to grade III.It could be seen that the plant landscape of Tianjin suburban agricultural sightseeing garden was generally well,and it had good comprehensive quality in aesthetics,growth status and service function.
