Study On Plant Patterns Of Greenbelt In Hangzhou Residential Area

The quality of living environment makes the foundation of human survival quality. Moreover, the residential green space is most close to residents’ daily life. It’s an important part of urban green space system, and the key to influence urban sustainable development. The current research on the plant configuration of residential area only stays in the description of concept and mostly research is about principle. Thus, building a feasible plant configuration model is an urgent and valuable research subject.In this paper, the configuration of residential green space in Hangzhou City is selected as the research object. And the mainly focused objects are more mature plant community in those residential areas about 6 to 10 years built in Hangzhou. By adopting the combination of individual and community investigation method, 9 typical plant community with 3 types of green space(Group green space, Building nearby green space, Road green space) are selected. The mainly research includes collecting the data about plant species and quantity, evaluating the ornamental character, and the questionnaire survey conducted for community residents. On this basis, by the analytic hierarchy process(AHP) plant landscape evaluation model, 5 quantitative indexes(species diversity, life-form diversity, landscape diversity, diversity of ornamental characteristics and landscape diversity sequence) are calculated. And by the resident questionnaire survey, 3 qualitative indexes are concluded. As the result, 3 residential area plant landscape composite scores and 9 plant community landscape evaluation score are concluded. By analyzing the evaluation results of the research, the plant configuration is summarized, which fitted with residential area including the Group green space, Building nearby green space and Road green space in Hangzhou.Through studying the plant configuration of the residential green space in Hangzhou, This paper aims at putting forward a feasible plant configuration mode model, which provides practical construction suggestions and application value for plant configuration research.
