The Analysis And Suggestion Of Investigation On Diversity Of The Park Plant In Changzhou

With the development of emphasis on the environment today,we pay more attention to the preventive actions of biodiversity.Biodiversity means the diversity of heredity,species and the ecosystem of the plants,animals,animalcule and the ecosystem.The preventive actions is mainly on gene,species and environments.Abundant species is the foundation of the development and the survival of human society.In our country we have done a lot of work on preventive actions of biodiversity and made the great progress.Urban Landscape Construction is city-centric integrated with suburban construction, affording the task of biodiversity conservation.Plant diversity is not only the basis of biological diversity,but also the standard to evaluate the levels and the quality of urban landscape.City Park itself should have abundant species.It is the important base for biodiversity especially for plant diversity protection,providing available environment for the development and protection.Analysis and suggestion on Park greenbelt plant diversity is of great significance.It is an essential requirement for planning biodiversity,an important measure to enhance biodiversity conservation,an essential foundational work of park management;the precondition to choose plants scientifically.This thesis field surveys and classifies the variety and quantity of trees,shrubs,vines,bamboo,aquatic plants and grasses in 16 representative Greenbelt Parks in Changzhou City together with the city tree,Flower and trees.It collects the data of tree species selection,tree structure,the proportion of Joe shrubs,evergreen and deciduous trees,and analyzes the various problems and shortcomings on types and number of plants.According to Changzhou region's climate and the environmental conditions of the soil,it brings forward the principles,recommendations and safeguard measures to rich plant diversity in Changzhou Park.Thesis provides a reference for planning of plant diversity development Changzhou Park,fills the blank of the city landscaping work for the establishment of national garden cities.It does good to make up the defect of plant diversity of the park green space and contribute to the planning,selection and the application of plant when we do the construction of green space of park.Our country has the abundant plant species,called as the mother of gardens worldwide.Changzhou,located in the northern subtropical wet monsoon climate zone, showing the obvious characteristics of transition from subtropical zone to temperate zone, is a city can be widely covered by a variety of plants.On basis of the survey in Changzhou,parks should confirm the planning of green plants diversity,and species and species,and confirm the proportion of species of evergreen and hardwood and their quantity.It is suggested that add the species of plants,esp.in the hardwood and increase the proportion of hardwood in variety and quantity.In collocation,arbor,frutex,and grass should be proportioned with folk style or local- color architecture and scenery in reason,for reflecting the local plants community structure.Utilizing the local plants at the first time, and introduce more fitted plants as soon as possible.Our aim is to build the plant diversity model with multi-layer,and to play the guiding role of plant diversity of greenbelt in the park.
