Research Of The Mode Of Economic Plant Landscape Of City Residential Area

People pay much concern and attention to the landscape construction of residential area which is closely connected with our life in the city.Obviously,afforestation is an important part. Currently, the sake of economic benefits, some residential areas landscape construction blindly pursue the temporary visual effects,ignoring the economically affordable principles, neglecting the harmony between the human and nature. In order to attract the public eyes,some pursue the exotic features and blindly use exotic species.In view of this, guided by the plant configuration theory, the passage uses many research methods,such as literature synthesis, field surveys, case analysis and so on.The plant configurations of residential area in Changsha were analyzed to establish a residential greenbelt plant configuration mode evaluation system,and form the framework of the economic type greenbelt plant configuration system. The main research results are as follows:(1) To make the statistics of landscaping plants of residential area in Changsha.The commom green plants are115species,of which there are47kinds of trees,40kinds of shrubs,12kinds of bamboo and vines,16kinds of ground cover plants and flowers.(2)Through researching and analyzing,and on plant configuration scientificalness, artistry and economy interpretation,to establish the evaluation system of the plant configuration mode.From the aspects of ecological adaptation, biodiversity, trees,bushes and grass community level, configuration, spatial relationships, seasonal changes, choice of specifications, planting density, management and maintenance,measure and assign a score to evaluate,to filter out the good plant configuration mode.(3) To explore the economic model of species selection, specification selection and spatial layout and to establish the economically green plant configuration mode system framework.The author hopes that the research can provide reference for theory and practice for the plant configuration of residential area in the future.
