Research On The Relationship Between Street Scale And Microclimate In Dangjia Village And Lingquan Village And Its Application

In the past 20 years,the role of traditional villages has changed from excavation and protection to protection and inheritance.As an important part of outdoor public communication space,street space takes people's demand as function and culture.Its spatial form often reflects strong adaptability to regional climate,which is particularly obvious in traditional village street space.However,due to various reasons such as economic cost,land use problems and so on,the modern village street construction presents a series of problems,such as the pattern of street space composition,single function and poor ecology,which not only can not meet the dual needs of street function and humanity,but also is not conducive to the inheritance and green development of village regional characteristics.The traditional villages of Dangjia village and Lingquan village are located in the loess tableland area,and the street space presents obvious spatial characteristics to adapt to the climate in Guanzhong.Due to the limitations of village land,the differences in the control of sunshine,wind and other climate factors in different streets and lanes in the same area are shown.Taking Dangjia village and Lingquan village as the research object,this paper summarizes the characteristics of street space environment in different scales,and explores the relationship between street scale and microclimate in traditional villages and its application strategy through the analysis of space elements and climate elements of street and lane in different scales.This paper first clarifies the spatial organization relationship of the streets and lanes of traditional villages and the scale of the streets,and takes the streets and lanes of Dangjia Village and Lingquan Village as the research objects to conduct investigations and collect the spatial information of their streets and lanes;Secondly,according to the measured data of street space in Dangjia Village and Lingquan village,the ideal models of street space in different situations are extracted.The light environment and wind environment in the street space of Dangjia Village and Lingquan village are analyzed qualitatively and quantitatively by using ECOTECT and PHOENICS software,and the relationship between the scale of traditional village street and microclimate is analyzed and summarized;Finally,based on the investigation of the current situation of the streets and lanes in the new village,combined with the actual problems,this paper summarizes the general application strategies of the construction wisdom of the microclimate environment in the traditional village streets and lanes in the actual street design,and takes new streets and lanes of Dangjia village as an example to carry out the case design.The following conclusions are drawn:(1)The street space of traditional villages has the characteristics of the extension of the street outline,the systematicness of the street network system,the variability of the spatial combination,and the growth of the street;(2)Under the construction strategy of "considering and comprehensively utilizing sunshine,wind and other climatic factors in different scale street space",the traditional village street space form structure often has good microclimate environment effect in the aspects of street extension,street network system and various linear space combination.The relationship between the scale of streets and microclimates of traditional villages is formed under the influence of the concept of "being of nature and skillful in change",regional characteristics,and clan etiquette.They are good at applying topography and landforms,street and lane planning and architectural layout,Street and lane space order,interface paving and other spatial elements of different scales and levels,which are a kind of street and lane micro-climate environmental construction strategy to avoid and use climatic elements.(3)In the modern village street planning,under the guidance of the microclimate construction wisdom of traditional village street space,In view of the landscape organization,road greening,activity site and interface pavement around the village,the rational design of the spatial elements of streets and lanes of different scales and levels can not only solve the problems such as the layout patterning,single function and lack of ecological sustainable development of modern villages,but also weaken the dominant control of a certain climate factor in the streets and lanes and balance the relationship between the inheritance and development of new village streets and lanes planning.
