Study On Application And Landscape Evaluation Of Woody Landscape Plants In Wetland Park In Hefei Area

The important value of woody landscape plants in wetland plant landscape is often neglected.At the same time,the problem of plant landscape homogenization in urban wetland parks is serious.Therefore,it is of great theoretical significance and application value to study the application and evaluation of woody landscape plants in a regional etland park,and it is the first time to evaluate the woody landscape plants in wetland park.Taking Hefei Zhongtie International City Wetland Park,Feicui Lake Park and Tangxihe ark as examples,this paper investigated 40 plant communities,conducted landscape valuation research based on beauty assessment method（SBE）,and adopted the method of combining theory and practice to carry out case reconstruction.The main research work and achievements are as follows:i)Through literature research,the cross relationship between woody landscape plants nd wetland woody plants was clarified.ii)Plant survey:46 species of woody landscape plants（including cultivated species）were commonly used in wetland park in Hefei;Based on data analysis,four application characteristics were summarized,including insufficient tree species,large proportion of fallen leaves,abundant ornamental types and concentrated application.iii)The aesthetic attitude of different evaluation subjects is consistent,and the arbor landscape is the most popular among the public.SPSS 26.0 software was used to conduct multiple linear regression analysis,and the factors that had a greater influence on wetland plant landscape were as follows:wild beauty（X₃）>and harmony of water landscape（X₂）>spatial structure（X₁）>landscape time series diversity（X₄）.The model was as follows:Y=-1.664+0.202X₁+0.239X₂-0.328X₃+0.161X₄iv)Summing up six major problems of plant landscape in Hefei Wetland Park:lack of obvious zonal characteristics,single planting form,lack of harmony with water landscape,weak ecological benefit,lack of artistic conception beauty,and inadequate conservation and management.Suggestions are put forward to solve these problems:excavating the advantages of native plant resources and improving the diversity;Enrich planting forms and landscape levels;Strengthen links with water bodies;Enrich biodiversity and improve ecological benefits;Excavate plant characteristics,enhance the beauty of artistic conception;Improve the maintenance management system.v)Example reconstruction:From high to low,the beauty degree of each park was the 1st section of Tangxihe Park>Feicui Lake Park>the 2nd section of Tangxihe Park>hongtie International City Wetland Park with the lowest score was optimized from aspects of plant planning,design and planting.optimize the landscape of Zhongtie nternational City Wetland Park with the lowest score of beauty degree from two aspects of plant planning,design and planting.
