| Urban Greenspace network is a complex organic wholeness which has many elements,multi-level and versatility.It contains rich content and covers a wide range of complex planning steps. With the introduction of system theory into Urban Greenspace network planning, you can effectively guide the planning process to promote the realization of the overall maximum functionality and improve the utilization of the limited green space.From the system point of view, this paper defines the concepts of system theory and urban greenspace network, reviews the study process of them, and obtains the urban green- space network planning research objects which are based on the system point of view. These research objects are elements, structure, function and system, which play a very important role in clearing the planning process and maximizing the overall function.Meanwhile,the paper analyzes the relevant planning cases which are based on the system point of view, discusses the concrete application of urban greenspace network under the basic principles of system theory,and then,it makes a preliminary exploration of planning ideas and planning methods of system-oriented urban greenspace network,and the specific process can be summarized as according to the status quo, sure planning objectives- combin with planning objectives, select elements- layout various elements, planning structure- subsystem optimization, construct the system superposition.Finally, the paper takes the Changshan as an example, responsed to the proposed planning theory explores and researches the planning process of Changshan urban greenspace network and the way of maximizing the realization of function basied on system theory.Linking theory with practice, this paper preliminarily tries to combine the system theory and urban greenspace network planning, and explore the planning method. It proposes new ideas and new views of urban greenspace network planning, which is a reference of other relevant planning. |
