基于AHP的海口市公园绿地植物群落景观评价与结构分析

公园绿地作为城市绿地系统的重要组成部分，其景观质量是衡量城市园林绿化水平的重要标志。以生态功能、景观功能与社会功能3方面构建海口市公园绿地植物群落景观评价体系，采用层次分析法对海口市9个主要公园绿地的植物群落进行科学而有效的量化评价。结果表明，海口市公园绿地植物群落景观质量整体优良，但优质植物景观群落配置相对缺乏。基于评价结果推荐了5个优秀植物群落景观配置模式，并提出以“近自然”复层式植物群落配置模式优化海口热带滨海城市植物景观，突出本土特征，强化景观功能，提高景观质量。

Landscape Evaluation and Structure Analysis of Plant Community in Haikou City Parks,Based on Analytic Hierarchy Process

As a critical part of urban green space,the landscape quality of city parks is an important symbol to measure the levels of urban landscaping.In this study,landscape evaluation system of the green space in Haikou city parks was conducted based on the ecologicaln,landscape and social functions.The analytic hierarchy process (AHP) was employed to quantitatively evaluate the plant community of nine major park green spaces in Haikou.The results demonstrated that the landscapes of plant community in Haikou parks were generally good.However,the high quality landscape configurations of plant community were relatively rare.Based on the evaluation results,five outstanding landscape configuration modes of the plant community were recommended.And “close to nature” stratified plant community configuration mode was proposed to optimize the tropical coastal plant landscape in Haikou,which could highlight the local characteristics,strengthen the landscape functions,and improve the quality of the landscape in Haikou.
