Urban-rural Green Space System Planning Based On The Ecological Network Structure

Nowadays,with the rapid development of economy and society,it also to a certain extent destroy the ecological environment of the urban and rural areas,especially the agricultural lands、woodlands、wetlands and other kinds of natural green space around the city are suffering from the pressures of city expansion and sprawl.So in most cases it tends to be at the sacrifice of the farming lands to ensure the rapid development of urbanization,then this leads to serious haze pollution、the urban heat island effect、deterioration of water environment、biodiversity loss and a series of ecological environment and ecological safety problems.It is well known that ecological crises are in increase with economic growth proportionately,it not only poses a serious threats to living environment and body health of people in the city,but also directly affects the city’s sustainable development and ecological security.So the research how to solve contradictions between urban construction and environmental protection 、 urban living environment and urban green ecological space is extremely urgent.Green space is one of the important foundations and the ecological security,which is in the urban ecological security and sustainable development.The dual social and economic structure in the past in our country between urban and rural areas produces the planning ideology of city-orientation,then it makes the situation that green space system planning has been focused on the city center of green space planning and construction instead of balancing the relationship between cities and countryside、human and nature in a way of thinking and planning strategy through overall urban and rural development.Thus when urbanization and industrialization are flourishing,the traditional urban green space system are unable to solve a variety of ecological crisis gradually.So in the face of the development trend of urban-rural integration,the establishment of green space system planning needs to take the whole urban and rural areas as the research object with strategic vision based on the local.At the same time,it makes the country’s natural ecology go into the urban green space system planning by using the landscape ecology theory and the ecological network pattern.Taking the urban ecological security and ecological construction as the breakthrough point,the rapid development of urbanization brings a variety of positive effects to people and disturbs and destroys the natural landscape pattern and ecological process around the city and the surrounding environment.It breaks the original ecological balance between city and the surrounding countryside,and triggers a succession of ecological crises.So it provides a feasible and necessary reality basis for building urban-rural integration patternof regional ecological network.Then ecological network is expounded and discussed detailedly in the aspects of space structure、establishing elements、functions、planning principles and planning approaches.Simultaneously,it builds frame of urban-rural green space system and ecological network based on the relevant theory of ecological red line.Afterwards,through the hackling of urban green space present situations and analysis of urban-rural trend,it puts forward the new category of urban-rural green space aiming to balance urban and rural development.Then,it hackles the green space landscape of urban-rural areas according to the research mode of “patch—corridor—matrix” and structures out the urban-rural green space system based on the ecological network pattern.At last,it takes the urban-rural green space system and ecological network planning in Shucheng county as example and introduces the vast rural natural environment into the city,not only creating the livable environment for citizens,also promoting the economic growth of the rural,and creating benefits in culture、economy and environment.
