The Research On The Plant Configuration Mode Of Yanghuyuan Wetland Park In Changsha

Urban Wetland Park is a place that can provide people with tours, leisure, entertainment and science education and other activities, etc, and also there are some parks own ecological and aesthetic value, which are important parts of national wetland system. What’s more, planting the landscape plays a very important role in the planning and design for urban wetland park, thus, the study of urban wetland park plant configuration is quite necessary. Currently, Changsha is creating a "Two-oriented Society", wetland park is also increasing. In this paper, we select Yanghuyuan Wetland Park for the study, and research this via two field surveys and questionnaires. In Wetland Park, Yanghuyuan Wetland Park can be divided into three types:terrestrial plant landscape; coast interpersonal landscape plants and aquatic landscape. This paper will comprehensively study the plants configuration mode of Yanghuyuan from ecological and aesthetic value. The results of the study are as follows:(1) Concluding that there are totally64species belonging to46families and58genera in Yanghuyuan wetland park. Among them, the proportion of terrestrial plants and aquatic plants is49:15, proportion of trees, shrubs, herbs, vines, bamboo is15:22:8:1:3.(2) Concluding the best configuration mode with the highest ecological stability from the three different biotopes.(3) The study is not equally between the standardization of SBE values. Among them, the sample14is one of the most popular in terrestrial plants landscape, the SBE comprehensive value of58.859; Sample to7is the shore of the most popular in the plant landscape, the SBE comprehensive value of36.716; Sample2is one of the most popular in the aquatic plant landscape, the SBE comprehensive value of6.607.(4) Synthetically comparing three different habitat optimization of sample area of plant configuration mode. Of sample11is better in terrestrial plants landscape, plant is configured to:Cinnamomum Camphora+Myrica rubra+Osmanthus fragrans-Prunus serrulate+Gardenia jasminoides grandiflora+Rhododendron pulchrum-Dianthus chinensis+Tagetes patula; Sample9is better in shore international plant landscape, the plant disposition for terrestrial habitats:Taxodium ascendens+Salix babylonica-Osmanthus fragrans var.semperflorens+Rosa chinensis+Photinia fraseri+Bambusa multiplex, aquatic habitat of the plant configuration is: the Typha orientalis community; Sample2is a good comprehensive evaluation of the aquatic plants landscape, plant configuration is:Spiked Loosestrlfe+Potamogeton crispus communities.(5) Summarizing the three basic of the yung liuheyuan lake wetland park plant configuration mode, namely:Joe-fill-grass, Joe and aquatic plant configuration mode.
