| The spatial form,structure,scale and layout of rural settlements carry the historical and cultural relics of the settlements and the wisdom of the villagers.However,in the process of rapid urbanization,the population of rural settlements has been largely lost,with some settlements having declined and died.The 19 th National Congress of the Communist Party of China proposed to implement the strategy of rural revitalization and promote the coordinated development of urban and rural areas.Rural revitalization is the demand of the times.Therefore,the study of rural settlements is necessary and urgent.After extensive field investigations on rural settlements,the author found that there are a large number of rural settlements with good spatial patterns in the surrounding areas of Hefei,and the settlement patterns,structures and environments are very distinctive.This paper selects 30 rural settlements around Hefei as the main research object,and carries out related research on settlement form and space environment.This paper uses quantitative and qualitative analysis methods to study the rural settlement patterns and spatial environment in the surrounding areas of Hefei from the macro,meso and micro perspectives.Firstly,the overall spatial pattern of settlements is studied from a macro perspective.The landforms within the city are divided into plains,undulating plains,shallow hilly plains,hills and mountains.At the same time,through the analysis of the environmental section,it is concluded that compared with the hilly and mountainous areas,the scales of the plains,the undulating plains and the plains of the plains are relatively large,the shapes are relatively regular,the water resources are relatively abundant,the traffic conditions are good,and suitable settlements are large.The area is larger.Settlements generally have the characteristics of living by road and living by water.Combined with field research,the relationship between settlements and farmland,vegetation,water system and roads and the overall layout form are summarized.Then,using quantitative analysis,the spatial structure characteristics of the settlement are studied from the meso level.By calculating the typical agglomeration aspect ratio λ and shape index S,the author defines the form of the settlement from a quantitative perspective.At the same time,using GIS and Depthmap software to analyze the spatial structure of the settlement,it is found that the banding and banding tendency are the bands.The linear skeleton structure has a high degree of integration and comprehensibility.The concentrated core is related to the strip axis.The clustered and clustered finger clusters are irregular network structures,and the overall integration and intelligibility are relatively low.The core of the settlement is consistent with the cohesiveness of the spatial form.The overall degree of each settlement has the characteristics of high central integration and low integration of edge regions.Finally,from the microscopic point of view,the interior space environment of the settlement is studied,and the inner street,building group,node space environment characteristics and current situation of the settlement are summarized,and the optimization suggestions are put forward.This paper analyzes the characteristics of the settlement patterns and spatial environment of the surrounding villages in Hefei City,and provides some theoretical support for the development of rural settlements around Hefei in the context of rural revitalization.In the process of revitalization and development,settlement development must respect the surrounding basement environment,excavate regional culture,and create our own unique texture characteristics,and it should combine the production and living needs of the villagers to improve the quality of the space environment. |
