| Under the dual background of Rural Revitalization and the establishment of double carbon goals,the sustainable development and optimal design and construction of rural human settlements have attracted extensive attention.Scholars in different fields have carried out indepth theoretical research,and professional design institutions at home and abroad have also carried out a lot of useful practical exploration.The essence of sustainable development of rural residential space relies on material space to realize the efficient recycling of resources.Today’s booming Ecological Rural design research is difficult to achieve effective response in three aspects: method and strategy,practical operation and spatial scale: in terms of method and strategy,rural areas with different characteristics of urban space and resource flow,The space construction mode and resource utilization mode similar to urbanization are often adopted in the process of its design and construction;In terms of practical operation,a large number of rural ecological design practices mostly simply superimpose ecological technology facilities and village spatial elements,which are difficult to adapt to the decentralized spatial layout characteristics of villages and the current situation of low-tech and low-cost resource utilization and management,and fail to take into account the style and features of rural built space;At the level of spatial scale,the discipline fields represented by urban and rural planning and architecture mainly focus on the ecological planning and design of the whole village area or the research on the design of green buildings based on Village residential buildings at the micro scale.There is a lack of attention and Research on the intermediate transition spatial scale,that is,the spatial type of village residential group,which affects the efficiency and validity of the metabolic flow and recycling of resources from bottom to top to a certain extent.From the perspective of interdisciplinary integration,relevant disciplines including ecology have integrated the concept of resource metabolism with the construction of sustainable development of urban space,and formed a large number of systematic theoretical achievements and practical experience,which can effectively inspire the research on ecological design of rural residential space.On the one hand,it integrates the resource metabolism theory of industrial ecology and agricultural resource management,and emphasizes the quantitative analysis of the internal flow metabolism law based on different resource elements（water,energy,waste,etc.）,so as to realize the efficient integration of resource elements and built space elements.On the other hand,a good resource circulation and metabolism process needs to be promoted step by step from bottom to top.From the perspective of architecture,taking urban metabolism as the main research direction of resource metabolism,aiming at the technical integration mode,spatial optimization mode and operation management mode of resource metabolism technology and various spatial elements（architectural space,open site,etc.）in different spatial scale levels（building monomer,group,block,area,etc.）,It has formed many research results that can be used for reference.Based on the above background and relevant theories,this study first systematically combs the relevant theoretical research on resource metabolism and human settlement space at home and abroad,the research on rural cluster space from the perspective of sociology,and the practical results of ecological design of rural cluster in urban and rural space based on the concept of resource metabolism.Secondly,it is proposed to build the resource metabolism system of village clusters with biomass resource metabolism as the link.Through the quantitative analysis of resource metabolism,the scale of village clusters（6-15 households）which are suitable for the characteristics of rural spatial resources in northern China and can realize the efficient metabolic cycle of resources is defined.Thirdly,the material flow analysis method is used to further determine the resource metabolism technology and facility elements,spatial form elements,and the staggered interactive relationship between various technology and spatial elements contained in the space of village clusters.Then,based on the northern rural spatial research and the case study of village cluster model,four village cluster spatial models including resource consumption and processing function and complete ecological infrastructure are constructed,and the four models are analyzed and compared.Finally,the village community construction mode based on efficient utilization of resources is applied to the design practice of Huangtuzhuang village,and a certain operational design framework is proposed to verify its feasibility and application value.The research results are a useful supplement to the theoretical research of ecological village based on efficient utilization of resources.The research design results also provide reference ideas and experience for the design methods,strategies and operation paths of ecological village based on efficient utilization of resources. |
