Study On Plant Configuration In Comprehensive Commercial Space

With the continuous development of social economy and the continuous improvement of people's living standards,people's ideas began to transform from the original simple view of buying and selling to the view of buying and selling related into aesthetics,art and nature.The design of plant greening in commercial space is not only a combination of simple stacking and placing of plants in a specific environment,but also a combination of modern aesthetics,psychology and ecological principles to further render the environment of shopping malls.This paper takes Tianhe City and Zhengjia Square as the research object.Through field investigation and data analysis,the plant allocation pattern,plant application frequency,plant community composition and plant diversity in the sample plots were studied,and the problems were found out and suggestions for improvement were put forward.Finally,Taiguhui was used as a commercial space for improvement.The main conclusions are as follows:(1)Through the allocation model of plants,it is concluded that the selection of plant species in Tianhe City is relatively simple,mainly ornamental herbs,supplemented by ecological functions,but the plant species lack diversity.The main allocation model of six sample plots in Zhengjia Plaza is the combination of large trees + herbs,small trees + herbs,herbs + ferns and a variety of herbs.There are more abundant levels,texture and color of the plant,but the combination ratio of tree and herb is slightly thinner than that of many kinds of herbs.(2)Through the frequency of plant application,we can understand the main plant species composition in plant community and the basic situation of plant allocation resources in commercial space.There are 9 kinds of plants in Tianhecheng,10 kinds of plants in 60% ? 20% frequency,and 2 kinds of plants in 20% ? 10%frequency.In Zhengjia Square,there are 6 kinds of plants which account for more than 60%,4 kinds of plants whose frequency is between 60% and 20%,and 16 kinds of plants whose frequency is less than 20% ? 10%.(3)According to the analysis of species composition,there are 19 species belonging to 16 genera and 11 families in seven sample plots of Tianhecheng,including 1 family,1 genera and 1 species of pteridophytes,accounting for 5% of allplants,18 species belonging to 15 genera and 10 families of angiosperms,accounting for 94% of all plants,and no gymnosperms are found.There are 26 species belonging to 24 genera and 18 families in six sample plots of Zhengjia Square,including 5species belonging to 4 families and 5 genera of pteridophytes,accounting for the total of all plants.19% of the total,21 species of angiosperms belong to 19 genera and 14 families,accounting for 90% of all plants.No gymnosperms were found.(4)From the analysis of plant allocation diversity in commercial space,it can be seen that the plant communities in Tianhecheng and Zhengjia Plaza are composed of small trees,vines and herbs,and their respective proportions are about 2:1:1 and2.3:5.1:1,respectively.Among them,26% are trees,21% are vines,52% are herbs,26% are flowers and leaves,27% are trees,12% are vines,61% are herbs,15% and46% are flowers and leaves respectively.By calculating and analyzing the average values of species richness index(dMa and dG1),diversity index(H'and D),evenness index(Jsw)of Tianhecheng and Zhengjia Plaza,we can see that species richness in tree layer of Tianhecheng is relatively low.Diversity degree is relatively low,species dominance degree is relatively high,while plant species richness is relatively high,diversity degree is relatively high and species dominance degree is relatively low in herbaceous layer;species richness is relatively low,diversity degree is relatively low and species dominance degree is relatively low in arbor layer of Zhengjia Square,while plant species richness is relatively high and diversity degree is relatively high in herbaceous layer.Higher,species dominance is relatively high.(5)By investigating and studying Tianhe City and Zhengjia Square in Tianhe Business District,this paper summarizes the shortcomings of plant allocation in commercial space,and takes Taiguhui as the later optimization sample plot,sums up the existing problems and corresponding optimization suggestions,as follows: 1)the selection of plant location;2)the selection of ornamental plant species in commercial space;3)the planting of commercial space;In terms of the form of placing objects;4)paying attention to plant function while taking into account artistic aspects;5)optimizing the proportion of plant composition and structure;6)plant conservation and management measures,etc.
