Evaluation On Campus Plant Landscape In Anhui Agricultural University

Anhui Agricultural University was founded in 1928.With the development of social,the pattern of campus' landscape has changed greatly and also has formed some characteristics,the aim of this study is to evaluate the plant landscape in Anhui Agricultural University campus.The main results was showed as follow:(1)The plants species in campus were collected and identified comprehensively.The results showed that there were about 388 species of plants,involving 101 families and 275 genera,the gymnosperm has 7 families 14 genera and 26 species,and 261 genera and 362 species in 94 families of angiosperm.According to Chinese seed plant areal-types by Wu Zhengyi,the areal-types of families was 12 and 15 on genera,the top 5 on areal-types of families is the Cosmopolitan with accounted for 35%,pantropical type with 25.74%.North temperate type with 7.92%,Tropical Asia to tropical America type with 6.93%,North temperate and the south temperate belt disjunction type with 5.94%.The distribution areal-types of genera are ranked in the top five.(2)Some typical artificial plant communities from the campus were selected,sampled.The quantitative character of artificial plant community on campus were investigated.The results indicate that the top 10 on tree layer' important value in the whole community of campus was orderly Sabina chinensis(11.12)> Sabina chinensis(10.7)> Bishofia polycarpa(7.39)> Cedrus deodara(7.35)> Osmanthus fragrans(5.98)> Pterocarya stenoptera(4.62)> Magnolia granddiflora(4.03)>Platanus × acerifolia(3.78);The important value in the shrub was in order:Pittosporum tobira(18.49)> Loropetalum chinense(11.79)> Chimonanthus praecox(7.45)> Punica granatum(7.70)> Lagerstroemia indica(7.15)> Cercis chinensis(6.45)> Euonymus japonicus Thunb.(5.25)> Malus micromalus(5.61)> Spiraea vanhottei Lour(3.37).The important value in herb layer was in order: Zoysia japonica(9.39)> Ophiopogon japonicas(9.02)> Oxalis corymbosa(8.65)> Alternanthera philoxeroides(7.79)> Dendranthema indicum(7.05)>Perilla frutescens(6.88)> Cynodon dactylon(6.21)> Solanum nigrum(5.28).Only on the basis of quantities of species : arbor: Platanus acerifolia,Juniperus chinensis Kaizuka,Bischofia polycarpa,Osmanthus fragrans,etc.,Prunus lannesiana,Ginkgo biloba,Bischofia javanica,no son.Shrubs: Chimonanthus,pomegranate,mahogany,Pittosporum tobira,crape myrtle,Malus halliana,Bauhinia,Heather and Pyracantha.Herb: Safflower Oxalis,Ophiopogon japonicus,Zoysia,Mani grass,iris,and so on.Simpson index of arbor layer,shrub layer and herb layer in all artificial plant community on campus was 0.934,0.898 and 0.915,respectively.Shannon Wiener index was 3.067,2.599 and 2.701,respectively.Pielou evenness index was 0.843,0.841 and 0.902,respectively.These indices can be used as indicators for the diversity of plant communities in the campus of Hefei city.(3)A preliminary evaluation model of Analytic Hierarchy Process was constructed.By visiting experts,following expertes' s opinions,the model was amended several times.On the basis of the indicators judged by many experts,the judgment matrix was constructed.Then,the weight of each evaluation factor was calculated using hierarchical analysis method,repeated adjustment until the same number of index CI<0.10.Target layer: landscape quality evaluation;criteria layer:visual effects,ecological function,service function;index layer: plant morphology(0.1765),plant green depending on the rate of 0.1537,litter(0.0307),color and seasonal variation 0.1338,line of sight and heterogeneity of community space community and plant level richness(0.1536),species richness 0.1148 the environmental impact 0.0574 0.0574 control(0.0228),can stay(0.0162),and hard landscape harmony(0.0212),education and Science(0.0519).20 artificial plants landscape of Anhui agricultural campus were randomly selected,and the evaluation model was constructed.Landscape evaluation index ranked in the top five are: Platanus × acerifolia + Platanus acerifolia halliana Malus+ Ophiopogon japonicus(73.40%),Ligustrum lucidum + rhombohedrons leaf Spiraea chrysanthemum + Oxalis corymbosa(71.72%),Lagerstroemia camphor + Manila grass(70.81%),Malus halliana + Photinia serrulata + Manila grass(49.46%),Sabina chinensis + Rose + Zoysia japonica(68.12%).The result showed that the plants landscape in campus is generally at a high level,there are 9 draw landscape unit to achieve grade ?,there is no grade ?.The quality of plants landscape in original campus are better,the environment in expansion area remains to be strengthened.
