Research On The Spatial Pattern Of Rural Sansheng In Hilly Areas

The 19 th CPC National Congress put forward the strategy of "revitalizing the villages".And building beautiful villages has become a major policy of national development,vigorously rectifying and constructing villages,optimizing the spatial structure of the villages,and improving the living environment of the villages.Production environment and ecological environment are the main contents of rural revitalization strategy.To realize the efficient and intensive production space,the beauty of living space and the harmonious development of ecological space are the fundamental strategies to carry out the rural revitalization.The development of "Sansheng space" should be adapted to local conditions,and the existing resources should be integrated and optimized according to the spatial function and type,so as to strengthen the rural spatial form,spatial layout,spatial structure construction,and continuously optimize the rural "Sansheng space".The "interphase" pattern is an important measure to achieve the great goal of revitalizing the countryside.By using the methods of typology and structural equation model,the identification,pattern,evaluation and optimization of rural tertiary space are studied.Firstly,it analyzes the connotation of "Sansheng space",classifies the living space,production space and ecological space according to the different spatial functions and land-use properties of the countryside,and clarifies the connotation,elements and identification methods of the three-birth space;Secondly,seven villages in Songshan Town are selected as typical samples to analyze the shape,layout and structural characteristics of the three-generation space,and to sort out the pattern law of different spaces and the overall pattern characteristics of the three-generation space.Third,based on the perspective of villagers use,according to the existing theory,literature and research,application structure The equation model is used to evaluate the spatial pattern of the third generation in rural areas in hilly areas,to investigate and analyze the villagers’ satisfaction with the spatial pattern of the third generation,and to explore the relationship and the law of action between the spatial pattern of life,the spatial pattern of production and the spatial pattern of ecology.Find out the important influencing factors of the satisfaction degree of the spatial pattern of the three students;Fourthly,aiming at the problems existing in the spatial pattern,spatial layout and spatial structure of Sansheng,the corresponding optimization suggestions are put forward according to the evaluation results.It is found that: firstly,the overall pattern of rural three-birth space mainly consists of three kinds of structures: two-ring-center,line-loop-center and three-ring-center.The three-birth space overlaps or intersects each other,and has compatibility,restraint and contradiction.Secondly,the satisfaction degree of spatial pattern of Sansheng is shown in the satisfaction of living spatial pattern,the satisfaction of production spatial pattern,and the satisfaction of ecological spatial pattern,and the influence of the three factors on the satisfaction of spatial pattern of Sansheng in turn decreases,in which the service of facilities in living space is reduced in turn.The spatial comfort has a great influence on the spatial pattern of Sansheng.In the production space,facility service and spatial reachability have a great influence on the quality of the spatial pattern of Sansheng,and ecological space.The effects of biodiversity and environmental suitability on the quality of spatial pattern of Sansheng were relatively small.Thirdly,the optimization of rural three-student spatial pattern should focus on improving the service quality of facilities,improving the accessibility of space and promoting the comfort of space.
