Green Corridor Planning And Control In Urban Space

Green corridor is a special form of land use which cannot be used for construction development while making an enormous contribution to the ecology sociality and economy of the city. It has not been yet fully researched, and, more confined to controlling the state of their own. However, in such an ecological, economic and social complex, it comes to be an important subject for us to find out how to motivate it so as to realize the efficient and intensive of land use. On the other hand, the linear space of green corridor is vulnerable to fault by disturbance of human, and it's vulnerable to degenerate and decay by misuse. As a result, it comes to be more important and urgent to guide the green corridor planning under the endurance of the habitat.Taking the green corridor of the urban space for study, the paper proposed how to construct complex green corridor based on the function analysis. It guides the integration of the urban space system and the optimization of land use through the construction of complex green corridor system.The contents of the paper are as follows:1. Chapter 1 and 2, intuitive understanding of the green corridor in the reality triggers thinking. Deepen the understanding of green corridor through looking back at the history of the development of green corridor, combing the results of theory and practice relevant. Profoundly aware of the necessity and practical significance.2. Chapter 3 analysis the function of green corridor from three aspects: ecologic, social and economic, proposes the concept of'complex green corridor', that is linear space with the contents of social, economic service based on ecological service. It emphasis the spatial conformity of ecological system of green corridor with urban land use as a carrier.3. Chapter 4 and 5 is the main thesis. It first does the planning of green corridor on the purpose of building'complex green corridor'. As the core of green corridor planning is evaluation and option, the paper makes an option of land use of green corridor by three aspects: suitability of land use, use of green protected zone and other land unfavorable of construction. Afterwards, constructs the natural and artificial green corridor respectively, based on which optimize the green corridor system. As a matter of fact, the process of composite green corridor is the process of selection and value judgment. After that we do some detailed analysis in this part of the paper on form selection and construction of green corridor, and, the key of planning and control mode of each level.Analyze and discuss gradually based on the construction of green space system, in order to realize'Guide the optimization of margin land use through the quality optimization and function recombining of linear space. It also extends the process of optimization to the hinterland which gradually changes the linear to banded linear, patchy optimization, and finally goes to the optimization of the overall urban land use.'Integration of space: analyzes the integration of green corridor and urban space in three aspects: total environment, linear environment and typical environment. Leads in the idea of"cell membrane system", realizes the integration of urban space through constructing a cell membrane system in urban space with green corridor for the benefit of mass exchanging and environmental protection.Land use: proposes the compatibility of land use, under the target of the improvement of land use efficiency and quality. Obtains four approaches to increase the compatibility through the analysis of the generation principle of land use compatibility. What follows the next concludes four forms of land utilization. We can improve the land use capability along the line of green corridor, intensifying the urban land use.4. In order to make green corridor planning feasible and workable, proposed construction guidance and technical support relevant.
