Research On Optimal Design Of Rural Space Based On Material Flow Analysis (MFA)

With the in-depth development of rural revitalization,the economic development level of China’s rural areas has been effectively improved,and the living environment has been significantly improved.But at the same time,similar urbanization village construction methods and one-way linear resource utilization patterns have also led to problems such as the reduction of rural ecological carrying capacity and the deterioration of the human settlement environment.In addition to the lagging level of infrastructure construction and other factors,it ignores the characteristics of rural production and lifestyles and the internal resource flow law of the human settlement space ecosystem.It is difficult to combine the characteristics of rural space to achieve efficient recycling of resources,and it fails to integrate resource utilization patterns with rural areas.The organic integration of the elements of human settlements is the main reason for the above phenomenon.The concept of resource metabolism derived from ecology and its quantitative research method centered on material flow analysis(MFA)provide useful enlightenment and reference in resource utilization and space optimization.Starting from the mechanism of rural resource flow and metabolism,exploring the efficient recycling of rural resources and optimizing the design method of rural space integrating the concept of resource metabolism is an important method and path to realize the transformation of rural resource production and use mode and spatial optimization and promotion.This research draws on the research results of the disciplines of resource management,agricultural economics,and industrial ecology.It starts with the analysis of rural resource cycle and metabolism,and takes the rural village space and its various resource flows and spatial elements as the research object.Aiming at the efficient use of rural resources,relying on domestic and foreign resource metabolism related theories and rural design case studies,clarify the element characteristics,flow characteristics and structural levels of the rural human settlement space resource system.Based on the material flow analysis method(MFA),establish a set of resource flow analysis system and spatial analysis method suitable for China’s rural resource conditions and socio-economic characteristics;construct a typical spatial model of rural resource metabolism,and explore the related technology,space,and social factors The interaction law between resource flow and rural space,and proposes space optimization methods and strategies suitable for the characteristics of the plain rural environment in northern China.Based on the optimization design method and strategy of the resource metabolism space,the research design is carried out with Xishan Village in Zibo as an example.First,investigate the resource utilization status of the village and obtain resource flow data information;secondly,use the material flow analysis method(MFA)to analyze its resource metabolism status,and visually express the village’s water resources,energy and nutrient flow metabolism system,revealing the village area The functional space and infrastructure types that are currently lacking in the system boundary to achieve efficient use of resources;thirdly,by implanting functional space/ecological infrastructure with resource absorption processing,adjusting the functional space layout relationship,etc.,to optimize resource flow paths,etc.Reconstruct and optimize the resource metabolism efficiency between different scales and levels in the village;finally,combined with the optimization strategy of the resource metabolism system,the bottom-up realization of the four scales of the village courtyard,neighborhood groups,built environment,and village space Optimized design of space form and environment style.The model of rural space construction proposed in the article is a useful supplement to the theory of rural human settlements.It is expected to provide new ideas and methods for ecological rural construction,which has important theoretical significance and application value.
