Study On Structure Characteristics Of Artificial Plant Community In Campus Greenland Of Tarim University

In this study,the study of campus greenbelt in Tarim University of South China was conducted.The plant species in the campus were statistically analyzed,and the plant community in each functional area was investigated by means of quadratic survey.The composition of the flora of the campus flora was analyzed by the survey data,the distribution type and the community structure of the functional areas.So as to provide valuable theoretical basis for the future construction of urban and campus green space,especially the selection,construction and management of campus green space in southern Xinjiang.The results are as follows:1.Flora features: Tarim University campus has 215 kinds of garden plants,belonging to 55 families and145 genera,the species coefficient is 67.44%.Advantages are:Leguminosae,Compositae,Rosaceae,etc.,the dominant species are not obvious;the flora distribution area is diverse,the geographical composition is complex,the floristic elements are the temperate distribution area type,followed by the tropical distribution area,with obvious warm temperate zone characteristic.2.There are 33 species,54 genera and 68 species of plant species in each type of functional area.Among them,the native tree species in the campus green tree species as a whole is not dominant,local shrub species scarce.Campus Artificial Plant Community Structure:(1)In the horizontal structure,the average plant community density in the functional areas was 720.8 plants / hm2,the density of plant communities in the teaching area green space,residential area green space,park green space,road green space and green space were 502,714,512,550and1326 Plant / hm2,teaching area green space there is a greater improvement of quality improvement space.The tree diameter is mainly concentrated in the ? diameter trees,which occupies a large proportion in each green space type.(2)In the vertical structure,the campus garden plant configuration pattern is basically trees and shrubs structure,the campus greening trees are highly concentrated in 2 ~ 8m range.(3)Seasonal structure,the investigation of the campus of the green all the evergreen shrub species,evergreen tree species are only Juniperus formosana,Sabina chinensis and Platycladus species,the species is relatively simple.In addition,according to Simpson index,Shannon-Wienner index and Pielou index analysis,the road green diversity index and evenness index are the best,the other is the education area affiliated green space,residential green space,park green space,green land production.3.The characteristics of the seasonal structure of 40 species of woody plants in Tarim University.The phenotypic analysis of 40 common woody plants in Tarim University was carried out.(1)During the whole activity of the plant: The leaf period is the longest,followed by green period,fruit period,dormancy period,autumn period,flowering period and germination period.Group activity period of 287 days,accounting for78.63% of a year.(2)Under normal circumstances,the plant phenophase began early,middle and late basically correspond to the end of the phenology of the early,middle and late.4.Campus green plant configuration optimization recommendations:Pay attention to Joe,irrigation,grass ratio and deciduous trees and evergreen ratio.Rich seasonal landscape,increase the winter tree species.The establishment of a high-quality campus green management team.
