Multi-Scale Quantitative Study On Rural Public Space In The Chuanxi Plain

As the pilot area for comprehensive urban and rural reform in China,the Chuanxi Plain has been flourishing since the integration of urban and rural areas.The traditional rural pattern of “Bamboo forest surrounded by small bridges” is quietly evolving.Under the new situation,the study of rural public space structure and spatial function layout is of great significance to guide the healthy and orderly development of rural construction.In the radical rural development of the past few decades,a series of problems have emerged in the rural public space of the Chuanxi Plain: blindly carrying out artificial form planning without the actual situation of the spatial form of the village,leading to the dislocation between function and form.Reflected behind this series of questions is our imperfection in the perception of multi-scale spatial structure.In the current planning of rural areas in the Chuanxi Plain,ranging from macroscopic macroscopic scales to microscopic community scales,these plans involve how to evaluate and optimize the spatial scales at different scales.However,the current rural planning lacks a practical multi-scale research space method,so multi-scale research on the public space in the Chuanxi Plain is imminent.The main research contents of this paper are as follows:This paper takes the rural public space in the Chuanxi Plain as the research object.Based on the traditional central theory of the public space in the Chuanxi Plain,combined with the theory of central flow and the theory of sports hierarchy,a new cognitive model for the public space in the Chuanxi Plain is established.Then use the spatial syntax theory to quantify this new cognitive model.In the course of the research,the method of field research and computer modeling comparison analysis was adopted to draw conclusions.In the computer simulation part,the three scales of large scale and mesoscale small scale were selected by observing the sensitivity of the index.Then the space syntax software was used to establish a model for the study of rural public space in the Chuanxi Plain.In the research part,the real situation was obtained through two methods: field visit investigation and Baidu map real-time road conditions.Finally,through the comparative analysis of the index values simulated by the model computer and the actual research situation,the deep logic of the rural public space hidden in the form of the surface of the Chuanxi Plain is explored to provide reference for the construction of the village.The main conclusions of this paper are mainly as follows:(1)About the construction of the model: According to the sensitivity of the spatial network to the scale,a three-level motion hierarchical network model of Ri=10000m,Ri=3000m and Ri=500m is constructed.This model can be directly used for rural public space planning analysis in the Chuanxi Plain,providing planners with a quantitative analysis of the public space in the Chuanxi Plain.(2)The combing strategy of spatial structure: From the perspective of spatial structure,the method of separating mobile hierarchical network and the strategy of integrating and transforming small-scale roads are proposed.And the author's opinion is also put forward for the location and layout of the village.From the spatial structure level,it will improve the quality of the Chuanxi Plain.(3)Layout strategy for spatial function: Analyze and compare the general rules of the representative functional points(commercial points,public activities,living activities)in the rural plains of Chuanxi and draw corresponding layout strategies to provide future practice.An important reference.
