Landscape Quality Evaluation of Green Space Plant Communities in Maoming City Park
Park green space plant community is an important indicator to measure the construction level of urban green space system,so it is necessary to evaluate the park green space plant community landscape.Using the hierarchical analysis method,we constructed a plant community landscape evaluation system,and conducted an empirical study with seven urban parks in Maoming as case sites.The study shows that:(1)in the criterion layer,the weight value of"ecological value"is(0.6483)>"landscape value"(0.2297)>"social value"(0.122)(0.122);(2)The top three ranked total weight values are species richness(0.1947),growth condition(0.1796)and community stability(0.1285),and the next two ranked are harmony with environment(0.0144)and landscape stay(0.0106);(3)Among the 50 landscape units evaluated,there are 3 of class Ⅰ,43 of class Ⅱ and 4 of class Ⅲ.43 and Class Ⅲ have 4,no Class Ⅳ,accounting for 6％,86％,8％and 0％respectively.The landscape quality of the plant communities in Maoming city park is generally good,but there is a relative lack of high-quality plant landscape communities.Based on the results of the study,the optimization of the configuration of plant communities is proposed.
