Studies On Greenbelt Plant Diversity And Scenic Beauty Estimation Of Zhengzhou City Universities Campus

Abstract:Campus landscaping is improvement part in campus environmental improvement and city landscaping,is the example area building the high tone and normalized urban greenbelt.Therefore,a perfect campus landscaping system to that student culture quality rise and cultural and ideological progress have the effect exerting a subtle influence on self's thinking,its important meaning is to guiding city afforestation and landscaping construction.In this paper,choose 8 different campuses greenbelt as research target in Zhengzhou city,pass landscape plant resources survey and inquire questionnaire,and researched the detailes such as woody plants diversity,plants choose and Scenic Beauty Estimation.The results indicated that:The marriage partner the main body of a book is studied with Zheng Zhou City what 8 is unlike the category colleges and universities greenbelt being,passes greenbelt general investigation and inquires into a questionnaire,the result studying, studying to have appraised go along indicates to colleges and universities greenbelt plant's diversity,colleges and universities plant choice and greenbelt beautiful scenery degree:1,Campus landscaping contain trees belong to 71 families,150 genera and 262 species.There were 60 families,133genera and 218species of angiosperms,3 families, 5genera and 5 species of gymnosperms.Trees concentrates distribution on rose family,olive family and legumes family.Rose family and olive family section account for 18.00%and 16.00%of all quantity respectively;and other section takes up proportion is less.2,The species richness of the ZZUNA,ZZIA,HNAU,PLAIE,ZZUSA,HNTUNA,HNRTUNA,HNCFT in tree layer was 106,102,86,58,49,45,34, 23.The species richness of the ZZUNA,HNAU,PLAIE,HNTUNA,ZZIA,HNRTUNA,ZZUSA,HNCFTin shrub layer was64,62,53,43,35,34,32,16.The Pielou evenness index in tree layer was HNAU(0.44)＞HNCFT(0.43)＞HNRTUNA(0.37)＞ZZUSA(0.33)＞ZZIA(0.32)＞HNTUNA(0.30)＞PLAIE (0.26)＞ZZUNA(0.25).In shrub layer was PLAIE(0.23)＞HNTUNA(0.21)＞ZZUNA(0.21)＞HNAU(0.20)＞HNRTUNA(0.16)＞HNCFT(0.09)＞ZZUSA (0.08) and lowest is ZZIA(0.05).Shannon-Wiener diversity index shows the identical trend with Simpsondiversity index.Shannon-Wiener diversity index in tree layer was HNAU(1.48)＞ZZUNA (1.29)＞HNTUNA(1.28)＞ZZUSA(1.22)＞HNRTUNA(1.19)＞HNCFT (1.18)＞PLAIE(1.17)＞ZZIA(1.09).In shrub layer was ZZUNA(1.25)＞PLAIE (1.19)＞HNTUNA(1.07)＞HNAU(0.85)＞HNRTUNA(0.76)＞ZZUSA(0.36)＞HNCFT(0.34)＞ZZIA(0.23)The tree layer was greater than shrub layer in Simpson dominantance index,in tree layer was ZZIA(0.2689)＞PLAIE(0.1165 )＞HNRTUNA＞(0.1083)＞ZZUSA (0.0933)＞ZZUNA(0.0868)＞HNCFT(0.0807)＞HNTUNA(0.0784)＞HNAU (0.0523 );In shrub layer was ZZIA(0.7781 )＞ZZUSA(0.6496)＞HNCFT(0.6227 )＞HNRTUNA(0.2545)＞HNAU(0.2234)＞HNTUNA(0.1246)＞PLAIE(0.1001)＞ZZUNA(0.0815)。3,Based the character and separate the 8 campus landscaping into a new and an old groups,and doαcorrelativity analysis,analysis the correlativity in the Pielou evenness,the diversity and the richness of the8campuslandscapingasabove-mentioned grad,in tree layer,F＜5.99,indicate that the difference of the the 8 campus landscaping was not similar;in shrub layer,F＞5.99,indicate that the difference of the the 8 campus landscaping in similarity level,and indicate that the shrub composed structure had great changed.4,In the process of street trees synthetical function valuation,basis on the other researchers selected the estimates,have led into a few new factors,the valuation to street trees are especially concrete,and by the method of principal component analysis,construet a mathematical made of street tree analysis,have reserved most information of admeasurement effectively(72.49%),having diminished the error that the artificial factor brings about,more all-round synthetical valuation street trees.and studies comprehensively on the 84 kinds of street trees.From this,the most adoptable street trees such as Platanus acerifolia,Salix babylonica,Fraxinus chinensis,are selected.Certain tending towards is of the same character on campus and choice of street trees.5,Analyse and estimate between buildings and central Greenland,and building correspondingSBE forecast equation:SBEs of greenland between buildings forecast equationSBE=62.656-0.021S_R+0.079S_A-0.015S_c-0.026S_G+0.167S_p-0.122S_O(R²=0.726) SBEs of central greenland forecast equationSBE=

similar among the not landscape college graduates,teaching and administrative staffs,landscape college graduates,landscape graduate studentes and experts,two group of the landscape college graduatesand the landscape graduate studentes and experts are most high in similarity modulus.Have special field background are sensitive to A and B/A in picture composition,no special field background are sensitive to C in picture composition,but in special field group, unitary key element is very difficult to arouse them favorable impression,therefore, rganizes certain quantity experts carries out valuation is meaningful.It has fountaines and large area change rich river systeminpartgreenbelt,between not special and special background group who have identical appreciation of the beauty intention,the fountain is exercising,can form rich changeful landscape,be fond of by different group,indicate people kissing water consciousness gaining the very high fraction obviously,therefore have high marks in the two kinds of group.After the factor gets rid of the waterscape,Increase to 7 to the notable factor appraising effect,among them being related factores are R,C,O,B/A and L+B+A,within 5 factors being related to,B/A is tall than other four factors correlativity is stronger,be that the rational collocation to the arbor and the sharb has more preferences that person is measured.
