Nanjing Yuhuatai Major Afforestation Species Dust Capacity And Green Flower Border Construction,

Ecological environment of Yuhautai area is in order, forest coverage is higher and centralize in the southof Qinhuan river. However, there are many problems of this area such as monotony of forest color, shortageof the flower's quantity, no-markedness of design and color, and the layout is not in enough. Predominance ofYuhautai area's traffic section is in evidence, but the influence of the compartmentation of the road andvehicle brought puzzle for the construction of whole area's ecological environment. Ability of the mostvirescence plants' dust blocking and flower borders' construction was researched in order to providetheoretical gist for the choice of greenbelt plants and the construction of the flower borders of Yuhautai area.The results were shown as follows:1 Ability of synthesis dust blockingThe dust blocking's ability of Prunus cerasifera Ehrh f. atropurpurea Jacp, Nerium indicum Mill,Maonia forunei, Liquidambar styraciflua L was highest. Magnolia grandiflora Linn, Acer palmatum Thunb,Populus, Robinia pseudoacacia, Cerasus serrulata,Aeer buergerlanum, Pterocarya stenoptera C.DC, Prunuspersica, Platanus hispanica, Ginkgo biloba's ability of dust blocking was lowest.2 Ability of dust blocking in different seasonsEight trees' ability of dust blocking in different seasons was researched which was Ligustrum,Pittosporurn tobit, Viburnum odoratissimum Ker-Gawl, Ligustrum Vicaryi, Euonymus japonicus, Fatsiajaponica, Platanus hispanica, Prunus cerasifera Ehrh f. atropurpurea Jacp. The quantity of dust blockingwas maximum in winter, which was minimum in summer.The quantity dust blocking of Ligustrum Vicaryi in four seasons were 0.0324rag/cm~2, 0.3060mg/cm~2,0.9078mg/cm~2, 103.8395mg/cm~2. The quantity of dust blocking in winter was 3204 times of the spring.3 Four trees' ability of dust cumulation blockingThe quantity of the four trees (Prunus cerasifera Ehrh f. atropurpurea Jacp, Ginkgo biloba,Cinnamonum camphora, Euonymus japonicus Thunb) was most in the first week after raining. Thepercentage of the four trees' quantity of dust blocking in the first week was 47.10%,51.48%,46.83%,65.36%in the whole of the three weeks. The Prunus cerasifera Ehrh f. atropurpurea Jacp's ability of dustcumulation blocking was highest, and that of Cinnamonum camphora was lowest.4 Mode of flower border's frameOn the base of ecology and landscape benefits, the layout of greenbelt was thought over and theconjunction of dot and line's frame of vireseence, prettification, fragrance was formed. Many plants werescreened out as the material of flower border's construction.ldiographic frame was one corridor, two belts, three patches, some dots.5 Construction of greenbelt and flower bordersThe layout of Yuhuatai area's greenbelt and flower borders' construction was divided into seven kinds,appertain greenbelt and flower borders, fence greenbelt and flower borders, road fence greenbelt and flowerborders, industry fence greenbelt and flower borders, production fence greenbelt and flower borders,watercourse fence greenbelt and flower borders, others fence greenbelt and flower borders and so on. Inallusion to the actuality of different greenbelt and flower borders' construction, the corresponding layoutmeasure was brought out.
