| With the modernization of urban development,people’s requirements for living environment,park green space,urban design and so on are also improved.Urban park green space is an important part of the city,is an important place for people to live,leisure and entertainment.Rhododendron is usually a frequent visitor to various parks because of its colorful flowers and graceful posture.Whether it is used as the main scene or as a background scene,the rhododendron plays an important role in the creation of park’s plant landscape.This paper was based on Hangzhou Botanical Garden(Maple Rhododendron Garden),Hangzhou Botanical Garden(Rhododendron Garden),Xiling Yinshe,Gushan Park,Wansong Academy,Huagang guanyu Park,and Taiziwan Park in Hangzhou West Lake Scenic Area,and Selected 31 landscape samples,adopted SD(semantic difference)method for landscape evaluation,compiled the data to obtain the comprehensive score of the samples,and drew the comprehensive evaluation curve diagram,and then compared with the specific evaluation score of each sample.To understand the specific differences,complete the quantitative analysis of the azalea landscape evaluation of the West Lake Scenic Area Park.The evaluation results showed that the sample 20 was the highest-rated sample,and the azalea landscape of Huagangguanyu Park performed best among the seven parks,with a high overall evaluation.According to the evaluation results of the SD semantic difference method,the paper combined with the factor analysis method to carry out further factor analysis on the sample data.The SPSS statistical software is used to analyze the landscape sample evaluation data.The four factors that produce the decisive effect are sensory factor,formal factor,environmental factor and natural factor.Thus,the process of the park Rhododendron landscape evaluation from qualitative evaluation to quantitative evaluation is completed.Finally,based on the analysis of the Rhododendron landscape evaluation results and the status quo of the park,it was found that there were problems in the construction of Rhododendron landscapes: 1.Single planting form;2.Insufficient plant diversity;3.Monotonous plant seasons;4.Don’t understand the ecological habits of azaleas.Based on the data results and the current situation analysis,four levels of landscape optimization strategy were proposed.Perceived factor level(1.Enrich plant planting forms,increase landscape level;2.native plants,enhance the sense of pleasure and belonging;3.regional culture,create a unique landscape),morphological factor level(1.Enrich plant species,increase landscape variation;2.Rich landscape color,pay attention to seasonal matching),environmental factor level(1.clear landscape boundaries,appropriate surrounding space),natural factor level(1.according to local conditions,respect plant growth habits;2.Strengthen conservation management and improve landscape quality). |
