基于公众感知的乌龙江东岸江滨复合型绿地景观视觉评价

以福州市乌龙江东岸江滨复合型绿地景观为研究对象，选取65张具有代表性的景观照片，由213名公众作为评价人员，使用美景度评价法对绿地景观质量进行评价。通过相关性分析群体差异与美景度的关系发现，专业、性别等群体差异对美景度没有显著影响。对江滨绿地进行景观要素分解，分为15个要素，每个要素2~4个类目，对数据进行多元回归分析，筛选出6个与美景度相关性较大的要素，保留的景观要素按贡献率大小依次为沙滩比(24.7%)、亲水性(24.1%)、植物生长状况(15.7%)、色彩对比度(14.3%)、天空比(12.3%)、景观硬度(8.8%)，以此建立乌龙江东岸江滨复合型绿地视觉景观评价模型。对美景度评分最高的3个样地景观进行分析发现，6个筛选的景观要素对公众喜好作出了良好的解释。本研究可为江滨复合型绿地的设计、优化与管理提供参考。

Visual Evaluation of Landscape of the Compound Green Space on the East Bank of Wulong River Based on Public Perception

Taking the compound green space landscape on the east bank of the Wulong River in Fuzhou City as the research object,65 representative landscape photos were selected,and 213 members from the public were invited to evaluate the green space landscape quality by using the scenic beauty estimation method.Through correlation analysis of the relationship between group differences and beauty degrees,it was found that group differences such as majors and genders had no significant impact on beauty degrees.Factors related to the riverside green space were divided into 15 items,each item was further divided into 2-4 categories.Through multiple regression analysis,6 high-correlated elements were retained,and the retained elements ranked in the order of contribution rate:beach ratio (24.7%),hydrophilicity (24.1%),plant growth status (15.7%),color contrast (14.3%),and sky ratio (12.3%).A scenic beauty evaluation model for the compound green space on the east bank of the Wulong River was established.The analysis of the landscape on the 3 plots with the highest SBE scores indicated that the 6 selected landscape elements provided a good explanation for public preferences.This research can provide reference for the design,optimization and management of the riverside compound green space.
