The Valuation On Artificial Plant Communities In The East District Of Agriculture University Of He Bei

Baoding government put forward the development strategies for building forest city.In 2004, the city was conducted greening census by Baoding Garden Bureau and Hebei Agricultural University.The greening condition of all of the campus in the city were within the scope of survey,including the east district of Agricultural University of Hebei.The philosophy of eco-garden was accepted by a great many gardeners gradually.It is the ultimate goal of the thesis that to build university landscape on the base of ecological theory.University landscape design,it is necessary to use plants to create a beautiful landscape visual arts,and also from the plant community structure,plant local characteristics,biological diversity and ecological succession principles of plants to give expression to ecological sustainable development of the campus.This thesis chose artificial plant communities of the east district of Agriculture university of Hebei as research object in order to make artificial plant communities of the east district of Agriculture university of Hebei more ecological,as well as,to enhance educational quality and afford reference proof for university green.The artificial plant communities of the east district of Agriculture university of Hebei was divided in to living quarters,cultural zone, academic area, and motor region. Author was going to proceed on studying plant communities and to give the reasonable community models for typical plots,which would improve the landscape of artificial plant communities of the east district of Agriculture University of Hebei.The thesis will state content from the following seven sections.The first section is prolegomena,which summarized the relevant conception of plant communities and plant landscape,basal theories,studying methods and content.The second section is literature summary,which expound the development conditions of university plant landscape and plant communities.According to summarize the researching conditions, the author found that there was little plant communities theory utilized to study university landscape.The third section, to the theoretical basis of community,according to investigation of the 14 plots for statistical overview which including the types of vegetation in Baoding and basic types and species composition of the east campus,bring a conclusion that dominated by deciduous broad-leaved trees and evergreen tree species fewer applications in the east campus.The fourth section is based on the investigation of artificial plant community structure in space research,including the communities of the level structure,spatial structure, species composition and seasonal structure. The next,according to comparative the score of each factor,select the three plots from high to low.In the fifth section,the author selecting three plots involving high,medium and low,by means of analyzing the number of features of species,community structure, vertical structure and seasonal,pointed out the main problems,at the same time,took out the modified methods.In the sixth section,the author analyze the rationality of plant communities further from the species, the species relationships within the community structure and community aspects of landscape effects,while recommend appropriate configuration of each functional area of the plant model.The seventh section summarized achievements of thesis and discuss further studied problems.
