基于AHP法与SBE法的郑州北龙湖湿地公园植物景观评价

Plant Landscape Evaluation of Zhengzhou Beilonghu Wetland Park Based on AHP and SBE Methods

以郑州市北龙湖湿地公园为调研对象,选取30个植物景观样地,综合运用AHP法和SBE法对调查样地进行评价。结果表明,准则层权重生态效益B_(1)(0.5889)>景观美学B_(2)(0.2519)>游憩服务B_(3)(0.1593);植物景观质量综合评价结果,Ⅰ级植物景观样地有9个,占样地总数的30%,Ⅱ级植物景观样地有15个,占比50%,Ⅲ级植物景观样地有6个,占比20%;SBE评价法的高分植物景观与景观美学程度呈正相关;利用Kendall′s W协和系数对AHP法和SBE法的评价结果进行一致性检验,渐进显著性为0.008<0.05,两种评价方法具有高度一致性。提出增加彩叶植物协调植物景观与周围环境的关系,改善水生植物群落结构的稳定性等优化湿地公园景观空间建议。

Taking Beilonghu Wetland Park in Zhengzhou City as the research object,30 plant landscape sample plots were selected and evaluated by comprehensive AHP and SBE methods.The results showed that the criterion layer weight was ecological benefit B_(1)(0.5889)>landscape aesthetics B_(2)(0.2519)>recreation service B_(3)(0.1593);according to the comprehensive evaluation of plant landscape quality,there were 9 GradeⅠlandscape plots,accounting for 30%,15 GradeⅡlandscape plots,accounting for 50%,and 6 gradeⅢlandscape plots,accounting for 20%of the total plots;the high score of SBE was positively correlated with the aesthetic degree of landscape;using Kendall′s W concordant coefficient to test the evaluation results of AHP and SBE,the progressive significance was 0.008<0.05,and the two evaluation methods were highly consistent.Through the analysis of the evaluation results,suggestions for optimizing the landscape space of wetland parks were put forward,including adding colorful leafy plants,coordinating the relationship between plant landscapes and the surrounding environment,and improving the stability of aquatic plant community structure.
