基于AHP-TOPSIS组合模型的植物园景观方案优选

选取功能定位、空间结构与形态、生物多样性、交通与游览组织、建设和维护费用、景观艺术效果等6项指标,运用层次分析法(AHP)和逼近理想解排序法(TOPSIS)构建了植物园景观方案优选体系,并对25份植物园景观方案进行了实证评价以验证模型的可行性。结果表明:AHP和TOPSIS模型应用于植物园景观方案优选的区分度较好,能对植物园景观方案的综合质量进行较为全面、合理、准确地评价,是一种简便、有效的优选方法。该方法也适用于其他类型绿地的景观方案的优选。

Preference of Botanical Garden Landscape Plans Based on AHP-TOPSIS Combination Model

A optimization system was established for botanical garden landscape planning based on the combination models of analytic hierarchy process(AHP) and technique for order preference by similarity to ideal solution(TOPSIS),in which 6 indices were adopted: functional orientation,spatial structure and form,biodiversity,transportation and tourism organization,cost of construction and maintenance,and landscape artistic effects.The model was verified by 25 botanical garden landscape plans.The results indicated that the distinctiveness was good when AHP-TOPSIS models were applied in the botanical garden landscape evaluation,and could make the landscape quality of botanical garden landscape plan more comprehensive,reasonable,and accurate,which is a simple and effective assessment method.The method is also suitable for landscape works preference of other types of green spaces.
