The Analysis Of Plant Community And Diversity On The Plant Of Urban Green Space In Anguo

With the development of urbanization and advancement of people’s standard of living,people have higher demand for urban environment and urban landscape. Plant-landscape ofurban green space can improve urban environment, share urban landscape and make thecity more beautiful. For a long time, urban green space as artificial Plant community, Citybuilders always consider the effect of urban landscape, and neglect ecological benefit.In this instance,how to bulid a plant community configuration which has muchsatifactory ecological function becomes a hotspot.In this paper, taking plant-landscape of urban green space of road, park and residentialarea in Anguo as the research objects, plant-landscape of urban road green space had beenstudied, The main research results are as follows:1The current status of urban road green space in Anguo was investigated,includingthe green plant species,the frequency of plants’application and the plants arrangement.(1) There are132kinds of species, belonging to66genera and35families. Treespecies rich families have Rosaceae, Oleaceae, Leguminosae, Pinaceae, Cupressaceae.(2) Among the road green space, the proportion of Sophora japonica Linn、Platanushispanica are the highest, Among the green residential,the proportion of Ginkgo Liloba、Cedrus deodara are the highest, Among the road green space, the proportion of Salixbabylonica are the highest.2The typical plant communities in urban green space have been Investigatedand analyzed.(1)Some species used too much. There are6-10kinds of trees that the importantvalues are more than10%. There are5-11kinds of shrubs that the important values aremore than10%.(2)The highest arbor layer Simpson index (D) and Shannon-Wiener index (H) is thecity park green space, the lowest is the road green space. The highest shrub layer Simpsonindex (D) and Shannon-Wiener index (H) is the green residential, the lowest is the roadgreen space.3The greening mode and vertical structure of Plant-landscape of urban green space in Anguo were analyzed with virtual maps,then the features of each modes were pointed out.4Development advices based on the analysis of development advantages anddifficulties of plant-landscape of urban road green space, were put forward so as to providereferences for the development of green space landscape of urban road in Anguo.
