The Study On Conservation Planning Of Biodiversity In Chuzhou City, Anhui Province

With the intensification of the process of urbanization, growth in population and increasing of human activity, urban environment has being deteriorating such as haze and fogs weather increased, freshwater resource got deficient, "urban heat island" effect becomes more and more severe and so on, all these made urban environment worsen for creatures, biodiversity reduced. The conservation of urban biodiversity has attracted more attention, the planning and implementation of conservation of urban environment is material base for realization of urban biodiversity stabilization and landscape richness, important guarantee for the urban sustainable development.The paper took the City of Chuzhou as a model to explore the patterns that city biodiversity conservation planning which coordinated with the development of urban on the basic of collection and analysis of plants, animals and ecosystem, hopefully to offer some theory and practice reference on biodiversity conservation to other cities in China. Main results in this paper are as follows:Through the investigation, the statistics and the analysis, there are 1367 species of vascular plant, belonging to 164 families and 541 genus. Inside city, including 16 species of fern belong to 14 families and 16 genus,54 species of gymnosperm, belonging to 8 families and 21 genus,1297 species of angiosperm, belonging to 142 families and 504 genus. In addition, there are 279 species of wildlife, including 18 species of mammals belong to 6 orders,10 families,9 species of amphibians belonging to Anura,4 families,14 species of reptiles belonging to 2 orders.7 families,171 species of birds belonging to 15 orders,41 families,67 species of fish belong to 8 orders,16 families in Chuzhou.From wildlife richness; vascular plant richness; diversity of ecosystem species; completeness of vertical stratification of vegetation; Species specific; invasion extent of external species and extent of biological invasions, these six aspects have carried out the biodiversity appraising. By using country as the basic unit and calculate biodiversity index (BI) to evaluate the biodiversity in Chuzhou city and come to be that the biodiversity index of municipal district of Chuzhou, Mingguang city, Fengyang country, Dingyuan country, Lai’an country, Quanjiao country and Tianchang country respectively are 34.084,32.003,30.346,29.811,26.141,25.904 and 25.347. The evaluating result is that belong to the common region on biodiversity are municipal district of Chuzhou, Fengyang county, Mingguang city, belong to the low region on biodiversity are Lai’an county, Quanjiao county, Dingyuan county and Tianchang city.On the baisis of investigation and analysis of the biodiversity situation in Chuzhou city, the planning of biodiversity conservation has been carried out in the levels of the genetic diversity, the species diversity, the ecosystem diversity and landscape diversity, and put forward the specific measure which has short-term and long-term signnificance...
