Study On The Plant Community Characteristics And Landscape Evaluation On The Green Of Modern Residential Areas In Fuzhou

Landscape of residential community is an indispensable part of the city greening and plays a very important role in improving city environment. The community characteristics and landscape effect constituted by different plants are important symbol of residential environmental quality evaluation.In recent years, the greening construction of residential area has already developed from the early simple tree-planting afforestation,to a new stage of plant configuration, In China, humanization and ecologicalization have been the two significant trends in residential landscape design. Many studies have cintriuted to the discussion in the residential area of plant configuration and landscape planning, etc. Currently, researches about Fuzhou residential landscape are concentered on plant landscape and overall planning,while comprehensive studies on plant community characteristics are very scare. The evaluation of the plant landscape of Fuzhou residential area has not developed a complete system. This makes Fuzhou residential area landscape plants and landscape design lack the most basic scientific basis. Therefore, this research studies the plant community characteristics and configuration of four modern residential area in Fuzhou,and proposes optimization countermeasures for existing problems,which may be helpful to provide a reference to the configuration of plant and plant community building in Fuzhou residential area.Based on the residentia area size, the green rate and Landscape features, etc., this paper selecets four residential areas as the representative residential landscape plants for sample investigation, Residential green space is divided into public greening, attached green space, building side greening and roadside greening. Thorough investigation and detailed statistical analysis have been conducted on plant configuration, community basic situation, community species composition, population characteristics, Plant use frequency and plant life forms in residential areas. Meanwhile, residential landscape Plants were visually evaluated from both professional and non-professional perspective. From the aspects of artistry and ecology,four types of green space plant landscape have been compared to understand the differences of different types of green space plant landscape in Fuzhou modern residential areas.The survey finds that in residential area, the plant communities were composed of 140 species of 112 genera of 59 families, including 71 species of trees,41 species of bush and 24 species of herbal (including 1 fern). The proportions of plants with different life forms in community were as follows:evergreen trees by 50.71%, deciduous trees by 12.14%, evergreen shrubs by 29.28%, woody vines by 2.85%, herbal by 17.85%. The sample area community are relatively rich in evergreen shrubs with plant life-form species, but less deciduous tree and the vine application.There are evergreen and deciduous broad-leaved forest,evergreen broad-leaf forest, palm grove and broadleaved deciduous forest.These four community types account for 55.56%, 18.52% and 25.92% respectively. The application of evergreen and deciduous broad-leaved forest are the most common ones,indicating that. Fuzhou modern residential area of plant community has certain localized regional features.The general rule of species richness, diversity index, evenness index are the same,with all tree layer higher than the shrub layer,indicating that the community stability of tree layer is higher than the shrub layer. The species diversity and richness index of public green space is the highest among the four green space. Evenness and diversity of tree layer species were higher in attached green space than in building-side green space,while the species diversity of-road green space is the lowest. Fuzhou modern residential area landscape plants have many problems,for example, the configuration modes are simple. In addition, the landscape is lack of characteristics.In terms of visual effects of plant landscape, public green space is the best and road green space is the worst. Combining with factor analysis,it was concluded that the visual effect of plant landscape in Fuzhou visual was consist of the four potential factors. The comprehensive evaluation of plants landscape, shows that public green has the highest score, while road green space has the lessest score.
