Current Situation Analysis And Research Of Nature Reserves In Chongqing

With the rapid growth of population, increasing of human economic activity, Has received the serious threat to biodiversity, loss of biodiversity is at an unprecedented rate, it has become a global issue of common human face. Biodiversity is the foundation of human survival, protection of biodiversity is an important way to create nature reserves.Chongqing nature reserves was founded in 1979, since the Jinyun mountain nature reserves was founded, after more than 30 years of construction and development, by 2012,58 nature reserves have been completed, including six at the national level, the municipal 19,33 at the county level, with a total area of 850657.4 hm2, accounting for 10.33% of the land area in Chongqing. In water conservation, soil and water conservation, ecological environment and biodiversity protection has played an important role, become the upper Yangtze river and the three gorges reservoir area is an important part of the "green barrier".Therefore, to carry out the scope of natural reserve, area, functional zoning, the object is to protect the basis of investigation, and management provide the basis for the construction of nature reserves, is particularly important and urgent.From on macroscopic in Chongqing 58 reserve system research is still blank, this paper USES the data analysis method, through a large amount of data and information, on the basis of the status quo of Chongqing’s 58 nature reserves survey analysis, the conclusion is as follows:(1) Nature reserves, the number and area of analysis. Chongqing 58 nature reserves, from the reserve level statistics,6 national nature reserves, with a total area of 241387.1 hm2; 19 municipal nature reserves, with a total area of 269598.3 hm2; 33 county a total area of 339672 hm2 in the nature reserves.(2) The structure analysis on the types of nature reserves. Chongqing 58 nature reserves, can be divided into five types.27 of forest ecosystem types,10 inland wetland and the waters ecosystem types,10 types of wild animals, wild plant type 9, two types of geological remains.(3) Nature reserves distribution analysis. Chongqing nature reserves are mainly distributed in the hinterland of the three gorges reservoir area and southeast of Chongqing, west of Hunan and Guizhou-Hubei mountain, center of Chongqing-west hills-low mountain, but look from the five regional reserve accounts for state-owned land area, Chongqing northeast area is the highest proportion of the distribution of qinba mountain region.(4) nature reserves in the population of permanent residents in analysis. Chongqing 58 nature reserves, the permanent population of 706524 people, including 80314 core, buffer 186255 people, the experimental area of 439955 people. Nature reserves of chongqing population distribution present situation as the experimental area has the largest population, followed by the buffer, the least is the core.(5) nature reserves management situation analysis. Chongqing 58 reserve, belonging to the agricultural sector, there are four reserve 4 reserve belonging to the environmental protection department,50 reserve belonging to the sheriffs department.(6) nature reserves, biodiversity analysis. Chongqing, a total of wild vascular plants,5549 species, belonging to 226 families and 1290 genera. Among them, a total of 586 fern species belonging to 47 families,118 genera; Gymnosperms 40 kinds, belonging to 7 families,25 genera; Altogether 4923 species of angiosperms, belonging to 172 families and 1147 genera.865 kinds of wild vertebrates, including 172 species of fish, amphibians,54 species of reptiles,61 species,432 species,146 kinds of animals.(7) The basic index of the management of the nature reserve in Chongqing is 76.21, and the management level is moderate.
