Ecological Network Evolving Research on Suzhou Greenbelt in the Process of Urban and Rural Integration

摘要

Using remote sensing(RS) technique, this paper attempts to extract the greenbelt information in city and countryside of Suzhou in 1986, 1998 and 2006. Based on the data statistics of RS, it also analyzes the spatial sequence feature of Suzhou greenbelt ecological network evolving in the process of urban and rural integration from the spatial distribution, quantity change and reducing speed of green space, to provide basic information for greenbelt system planning of urban and rural integration, and foundation for space governance and spatial planning in city and rural area.
