Studies On The Characteristics Of Plant Community In Urban Park Green Space Of Handan City

As time progress, economic development and people's environmental awareness, people living in cities increasingly desire a good living space and beautiful living environment, thereby increasing the level of urban greening, speed up the improvement of the urban environment construction of an ecological, conservation, sustainable development, cities increasingly put on the agenda. Park is the city's most important and most representative of Greenland. Plant community is the basic unit of Parks, Park System is the basis of ecological function, is to improve the park green landscape richness premise. Build a scientific and rational plant community structure can the Parks stable, efficient and healthy development.In the ecological garden city, Forest City, Mountain City, Garden City, under the guidance of the theories, to improve the urban ecological environment, and create beautiful urban landscape, and promote sustainable urban development, construction of urban landscapes of green building to become the primary task of the modern landscape is important factor in the sustainable development of cities, so urban landscape of the construction of plant community is increasingly important.In this paper, Handan landscape based on a survey of resources to different types of Parks for the study of plant communities on trees, shrubs and lianas were investigated in detail, and plant species composition, tree species importance value, species application frequency, high level of tree species, diameter class, tree species, community structure, species indicators of health status of the seven characteristics of the survey data were calculated on the results and the practice of data compared and analyzed the existing plant in Handan City Parks problems and the shortage of plant landscaping. Basis of the analysis in the investigation of plant species on the basis of principle of selection, combined with the city of Handan City, climate, soil and floristic characteristics, urban construction conditions, the economic base and cultural heritage and ecology of plants and habits, recommends a group of appropriate Handan introduction, domestication, development and utilization of plant species. And on this basis, the use of ecological principles to create a stable structure, shape beautiful, eco-efficiency, energy conservation, sustainable development with local characteristics and plant communities for the purpose of the ecological functions of different plant communities and landscape configuration mode landscape a detailed discussion and specific design.The results show that:There are 50 families, 100 genera and 149 species in urban park of Handan city. There are 3 families, 3 genera and 12 species belong to evergreen trees. There are 25 families, 37 genera and 53 species belong to deciduous trees. There are 9 families, 10 genera and 13species belong to evergreen shrubs. There are 19 families, 41 genera and 56 species belong to deciduous shrubs. There are 4 families, 6 genera and 6 species belong to vines and 6families, 6 genera and 8 species belong to herbaceous layer.Essential value of tree species ranking for Platanus orientalis>Cedrus deodara>Ligustrun lucidum > Sophora japonica > Populus tomentosa > Ginkgo Liloba >p.bungeana>Robinia pseudoacacia>Koelreuteria paniculata>Sabina.c.cv.kaizuka. Essential value of shrubs species ranking for Prunus cerasifera Ehrh.AtropureaJacq>Euonymus japonicus>Rosa chinensis>Hibiscus syriacus>Prunus triloba>Photinia serrulata > Ligustrum vicaryi > Ceris chinensis > Forsythia suspensa > Lagerstroemia indica.The utility frequency of commen plants ranking for Ligustrun lucidum, Platanus orientalis, Euonymus japonicus,Rosa chinensis,Cedrus deodara etc, reflecting the composition of Handan City Parks plant more similar to the lack of a rich portfolio and changes.The species with a large height are Platanus orientalis, Sophora japonica, Fraxinus chinensis, Populus tomentosa, cedrus deodara,sabina chinensis. The park's plant health status of good, young plants in the period, is conducive to stability and development of plant communities, to give full play to plant landscaping features that make plant landscape at its best. To plant community diagnosis and in the foundation the utilization ecology principle, take builds the ecology, artisticly, stable, continually, the highly effective frugal plant community as a goal, recommends some to satisfy different function request the floristic component and the community disposes the pattern, for the next Handan botanical garden construction reference.
