The Study Of Garden Plant Design And Evaluation Of Plant Landscape In Changzhou

The garden green space is an important part of urban green space system.It can reflect the environment of the whole city and the residentes as the"window"of one city, which can improve urban ecological environment, sharp urban landscape and make the city more beautiful.This paper takes main five garden green space in Changzhou as the object of investigation and analysis.It chooses ten typical artificial plant communities which are relatively stable to investigate and analysis. According to the theorem of ecology, the formation of species,the distribution of region, the frequency of plants' application, species diversity and the proportion of plants are analyzed.Some suggestions and optimization modes are given to the plant arrangements and landscape based on the study of the struction of plant design and the evaluation of plant landscape.Main research results as follows:1. The paper investigates the current status of main urban garden green space in Changzhou, including the green plant species,highth, shape,color and the covery and so on.2.The paper investigates and analyzes the characteristics of plant design of ten main garden green space in Changzhou. Main contents as follows: The distribution of region, the growth of plants, the frequency of plants'application and species diversity and so on .3. The reasonable evaluation system is set up based on the investigation and analysis.The paper evaluates plant landscape, by selecting ten evaluation factors from two aspects using Analytic Hierarchy Process method.According to the results of plant landscape synthetic evaluation,the grading of plant landscape is determined and the characteristic of plant landscape is analyaed.4. According to the results of plant landscape synthetic evaluation, the paper proposes the suggests and optimization modes of plants configuration and landscape in garden green space.These provide strategy and proposal to construct and plan urban garden green space.
