摘要: 从生态价值、资源价值和美学价值三方面构建了观赏草景观效果评价指标体系,并应用模糊综合评判方法对北京植物园和南中轴公共绿地的观赏草景观效果进行了评价.结果表明:通过该评价体系得出北京植物园和南中轴公共绿地观赏草景观很美的隶属度分别为0.459和0.413,美的隶属度分别为0.302和0.301.评价结果与公众感觉和反应一致,说明该方法适用于观赏草景观效果的分析评价.

Abstract: A composite index system for landscape evaluation of ornamental grasses was built from the aspects of ecological constraints, resources requirement and aesthetic values, and the ornamental grass landscapes in Beijing Botanical Garden and in Nanzhongzhou public green spaces were evaluated by fuzzy synthetic assessment (FSA) method. The results showed that the scores of “very apt” for the ornamental grasses in Beijing Botanical Garden and in Nanzhongzhou public green spaces were 0.459 and 0.413, respectively, while those of “apt” for the two landscapes were 0.302 and 0.301, respectively. The evaluation results were consistent with the public feedbacks, suggesting that the composite index system and FSA method were applicable for the landscape evaluation of ornamental grasses.
