Study On Diversity Of Gardening Plant And Natural Degree Of Gardening Plant Community In Hengshui

In the21st century, the urbanization process of Chinese is accelerating,theprominent contradiction between urban development and ecological are also increasingly.Biodiversity has become very important in the current ecology research. City plant as animportant component of the urban ecosystem, its diversity has always caught muchattention."Natural" as a new direction for urban greening, it will play an important roleon the promotion of Chinese urban greening. In this context, how to create a scientificconfiguration with good ecological functions of the urban landscape plant communitieshas important practical significance. In this paper, as a starting point for the purposes,Hengshui City Green plant diversity and naturanessl of garden plant communities werestudied to provide theoretical guidance for the construction of eco-garden city.In this paper, I selected a representative sample of194plots (each plot area of100m2) in the parks, the road green spaces and green residential area of26survey sites inHengshui.I has detailed the investigating of the plant species in the plots,analyzingdifferent type of green plants composition, plant diversity, and plant communities naturaldegree. The results show that:(1)In197plots, there are132kinds of species, belonging to66genera and35families. Tree species rich families have Rosaceae, Oleaceae, Leguminosae, Pinaceae,Cupressaceae.(2)Among the park green space, the road green space and green residential areathree green types, the proportion of arbor species are the highest, followed by shrubs,herbs minimum. In the park green space plant species is the most widely used, reaching84.09%of the plant species surveyed; road green space and green residential area asmaller proportion of plant species, did not reach50%of the total survey types.(3)There are ten arbors importance value is greater than10%in Hengshui City Park.Ash and Sophora japonica are the main greening tree species in Hengshui City Park.There are eight shrubs importance value greater than10%, Euonymus japonicus andCalifornia Privet are excessive used. The application of the shrub species focused on afew of species.The highest arbor layer Simpson index (D) and Shannon-Wiener index (H) is Yi Shui Park, the lowest is People’s Park. The highest shrub layer Simpson index (D) andShannon-Wiener index (H) is Youth Park, the lowest is China Park. The highest herblayer Simpson index (D) and Shannon-Wiener index (H) is Yi Shui Park, the lowest isPeople’s Park. The highest Arbor layer Pielou index (J) is Youth Park, the lowest isPeople’s Park. The highest shrub layer Pielou index (J) is Youth Park, the lowest is ChinaPark. The highest herb layer Pielou index (J) is Yi Shui Park, the lowest is People’s Park.The natural degree of Hengshui City Park is in the order: People’s Park> Yi ShuiPark> China Park> Youth Park(4)There are seven arbors importance value is greater than10%in Hengshui CityRoad Greening. Evergreen species is not taken seriously in the road greening. There areseven shrubs importance value greater than10%. Evergreen and deciduous collocation isreasonable. Applications of part of species proportion is too large, native trees of speciesused is less， landscape is monotonous.The higher arbor layer Simpson index (D) and Shannon-Wiener index (H) isYongXing Road, ShengLi Road, QianJin Street, RongHua Street, ChangMing Street,ZhongXin Street, RenMin Road and YuCai Street,The higher shrub layer Simpson index(D) and Shannon-Wiener index (H) is ChangMing Street, QianJjin Street, RenMin Road,RongHua Street, ShengLi Road, YongXing Road, HePing Road, KangTai Street,ZhongHua Street, ZhongXin Street and HeYangXi Road, The higher herb layer Simpsonindex (D) and Shannon-Wiener index (H) higher ChangMing Street, QianJin Street,RenMin Road, RongHua Street, ShengLi Road, YongXing Road, HePing Road; Thehigher arbor and shrub layers Pielou index (J) are ChangMing Street, QianJin Street,RenMin Road, Yu RongHua Street, ShengLi Road, YongXing Road, HePingRoad,KangTai Street, ZhongHua Street, ZhongXin Street, HeYangXi Road, YuCai Street,The higher herb layer Pielou index (J) is QianJin Street, RenMin Road, ShengLi Road,YongXing Road, HePing Road, KangTai Street,ZhongHua Street, ZhongXin Street,HeYangXi Road, YuCai Street.The natural degree of HengShui City Road is in the order: RongHua Street>YongXing Road> QianJin Street> ShengLi Road> RenMin Road> ChangMing Street.(5)There are six arbors importance value is greater than10%in Hengshui CityResidential area.Evergreen species is not taken seriously. There are six shrubs importancevalue greater than10%. Evergreen and deciduous collocation is reasonable.The arbor layer Simpson index (D) and Shannon-Wiener index (H) the highest isShengShiHuaTing Area, the lowest is Oil family member courtyard. The shrub layerSimpson index (D) and Shannon-Wiener index (H) the highest is YiShui Aera, the lowestis Oil family member courtyard. The herb layer Simpson index (D) and Shannon-Wienerindex (H) the highest is LiJingMingDu Area, the lowest is Oil family member courtyard.The Arbor layer Pielou index (J) the highest is YiShui Area, the lowest is TaiYangCheng Area. The shrub layer Pielou index (J) the highest is YiShui Area,the lowest is Oil familymember courtyard. The herb layer Pielou index (J) the highest is LiJingMingDu Area, thelowest is TaiYangCheng Area.The natural degree of Hengshui City Residential area is in the order: Oil familymember courtyard> YiShui Area> LiJingMingDu Area> ShengShiHuaTing Area>TaiYangCheng Area.
