摘　　要：城市街道绿化是城市景观的重要组成部分。文章以海口市59条生活型街道(段)为研究对象,基于植物本体因素和街道环境因素构建评价指标体系,应用熵权TOPSIS法和SBE法对街道绿化的观赏性进行评价。结果表明:对生活型街道绿化观赏性影响最大的是花篱地被种植密度,影响最小的是乔灌木种植密度;形相丰富度、植物种类丰富度、色相丰富度、植物水平空间层次率、植物垂直空间层次率、绿视率对街道绿化的观赏性也具有一定的影响力;海口市生活型街道绿化的观赏性水平整体一般。根据研究结果,对绿化观赏性较差的街道提出相关更新策略,为街道植物景观规划提供参考。Urban block greening is an important component of the urban landscape.The paper constructs the evaluation indicator system based on the essence factors of plants and the environmental factors of blocks and evaluates the greening ornamental value of the 59 residential blocks selected in Haikou City using entropy weight TOPSIS method and SBE method.The results show that the planting density of flowering hedge has the greatest impact on the ornamental greening of residential blocks,and the planting density of trees and shrubs has the least impact.Other factors,including morphology richness,plant species diversity,hue abundance,horizontal and vertical spatial hierarchy of plants,and green looking ratio also have a certain influence on the ornamental level of block greening.The landscaping of residential blocks in Haikou City is at average level.According to the research results,relevant renewal strategies for blocks with poor greening ornamental views are proposed to provide references for the planning of block plant landscape.
