The Reserch On Binzhou City Landscape Pattern Of Central Urban Greenbelt System

As an emerging city-based industrial development city, bingzhou shi rises rapid expansion of the city, which brings a rare opportunity for the construction of urban greenbelt system. However, there are many problems on construction like soil salinity, windy drought weather in spring time and cold, long winter days, characteristics of industrial structure as well as historical problems of old urban green space of old town districts (dense building space, small green areas, simple species of trees and difficulty to transform) all bring challenges for the integrity, continuity and sustainability of landscape pattern of urban greenbelt system.The writing focuses on the analysis of landscape pattern of urban greenbelt system, applying related landscape ecology theory, using bingzhou image maps of2008, and supported by GIS, to make classification and information extraction of landscape pattern of central urban greenbelt system to form an information base of this system; separately calculates the landscape patches index and landscape level index in FRAGSTATS, then makes level division and distribution analysis, which enable to achieve a quantitative analysis of the green space in the space scale.The phenomenon of unbalance on configuration of the main urban green space in bingzhou shi revealed from these aspects:other green areas occupied nearly65%of the city green space; main green landscape is small, median plaque, lack of big scaled plaque; uneven distribution of green landscape types, low landscape diversity and advantages of other green areas landscape; the high overall degree of fragmentation, the street green areas are the highest degree of fragmentation, with high degree of fragmentation of green residential area and attached green areas; the degree of fragmentation of eastern district is lower than the degree of western district, but the aggregation is smaller than western district, which is the result of the effect of several large scale green areas patches of eastern district; besides, the old town districts in eastern district are lack of green area and current extant green areas are in high fragmentation level and poor continuity.Through the analysis of the status of green areas pattern and the influencing factors, the writer proposes some optimization strategies eventually, and points out that it is also important to emphasize upon the biological diversity of green area, and improve the stability of the plan communities of green landscape at the same time.
