Research On Landscape Planning And Design Of Suitable Rural Community Based On Material Energy Flow Cycle

People take a large amount of materials and energy from the nature and discharge wastes beyond their load carrying capacity.It is urgent for us to explore a balance between the input and output of the material energy flow circulation system to alleviate the single situation of resource consumption and garbage discharge in the city.Agriculture,a naturally closed circular system,will be a fitting point,while community agriculture in China has been in the gray area of urban construction and management.Agriculture is absent in the community for a long time.The spontaneous community agricultural activities not only cause social disputes but also lead to disordered landscape effect,which leads to the loss of the real meaning of community public space in our country--from "collective ownership" to "collective absence".This paper attempts to solve the above problems by starting from the study of matter energy flow and organically implanting the natural closed circulation system of agriculture into the community space.Firstly,this paper discusses the material energy flow,agricultural landscape,agricultural community and other relevant literature,and firstly summarizes the three characteristics of the metabolic flow of material energy--permeability,efficiency and circulation--in chapter 2 by using the theories of landscape ecology,permaculture of portman and circular economy.With a kind of five dimensional space thought to excavate the potential community suitable for agriculture space-the matter energy flow into the agricultural space construction.The third chapter puts forward the basic means of developing potential suitable rural communities,which are divided into two aspects: the activation and regeneration of micro space and the fifth dimension of macro space.The macro space reserves the productive space,optimizes the reorganization landscape pattern.Through the above content can flow of three kinds of patterns and agricultural community of flow space exploration,in the fourth chapter discusses how to establish suitable farming community landscape design based on content can flow method,through the study of the relative position of patch,corridor and its physical properties,positive interaction between species,plant symbiotic planting,animal migration routes can create a habitat to construct objects efficiently circulating landscape pattern.It is applied in the practical design of the agricultural landscape of yangshan fish painting field in wuxi,which is divided into three parts: preliminary analysis,ecological elements combing,andlandscape planning of the material energy flow.The conclusion is as follows: the community is based on three-dimensional space,four-dimensional time performance,and the fifth dimension(material and energy dimension),so as to form the ecological balance and overall harmonious landscape effect.The whole process of agricultural production and material energy flow cycle is organically integrated into the community space,and the original linear metabolic system is transformed into an efficient circulation system with input and output decrement.The biological relationship reconstruction and physical attribute of positive interaction of agricultural landscape elements are used to construct the landscape pattern of flow space...
