The Investigation And Research On Road Afforestation Of Mancheng

Based on the city is the county township road green status field survey wereanalyzed tree structure, and the use of illegal Patel determine the index weight, toestablish evaluation index system adaptable species, In the township of ManchengCounty comprehensive benefit of the road greening were analyzed and evaluatedscientifically and reasonably, Clearly the main problems the city is the county townshipstatus of species in terms of the existence of the application of road greening, andinitially proposed solutions to this problem. To provide a viable urban road design basisfor afforestation， Plays a very important role in guiding the development of urbangreening。The main results are as follows:Through the12Township Mancheng County trunk observation, measurement andstatistics of road greening tree species found Mancheng County main road greening treespecies including Willows, Paulownia, pagoda tree, Chinese pagoda tree, poplar,ailanthus, Qingtong, sycamores, plants, elm, torch tree, acacia, Koelreuteria paniculata,acacia tree, Ginkgo biloba, Chinese flowering crabapple, Sabina chinensis, cedar, biotaorientalis, Pinus tabulaeformis,, purple leaf barberry, Chinese rose, big leaf boxwood,gold leaf privet, sandy lam, Japanese persimmon, pewter, flowering plum, hibiscus,purple Ye Li24genera and18families.Through the analysis we can see that the township Mancheng County roadgreening tree species diversity index is low. Index of Tuo Nan Xiang greening treespecies diversity for a minimum of1.093,the town of mancheng road greening speciesdiversity index is the highest in the2.071.The township Mancheng County trunk road greening tree species, DBH averagespecies diversity index is0.708, and the road greening tree species diversity index in the1.219-0.293,Overall diameter of each villages and towns main street road, ManchengCounty, species diversity index is low. Road greening diameter trees most of the<25.4cm, is in its infancy. The main road greening tree species in the trees, The tree ismuch larger than the number of shrubs.The establishment of a comprehensive evaluation index system, Thecomprehensive benefit evaluation system of road greening tree species of Manchengcounty. Re-established the tone of the county of mancheng road green trees and backbone species. The survey found that the County of Mancheng Road Greeningproblems, as follows: Tree species composition is not rich and reasonable; Tree speciesdiversity index is low, the lack of plant diversity; Tree species selection of imbalance,play a skeleton tree restricts the ecological and landscape function; Green road sectionsin the form is single, road greening rate is low, the ecological function is fragile; Usingfewer plant species, community has the advantages of simple structure, configuration ofsingle; Colour is drab, the seasonal landscape is not prominent; Conservation andmanagement is not standardized, not in place.In view of the existing problems, puts forward the following countermeasures:Scientific selection tree species, improve the level of road greening; Strengthen thearbor, shrub and herb flowers should be research, rich garden plants; Pay attention to theproportion of tree species and reasonable configuration; Improve the planning andconstruction of city road green landscape, strengthening the research on planning anddesign; Fast-growing species with slow growing species combination, optimizing theage structure of community; Increase plant species, enrich the seasonal landscape;Strengthen the maintenance and management of road greening.
