| Rural space is at the end of the territorial space planning system,and is an important starting point for realizing rural revitalization and the modernization of national governance.Scientific division of village types and overall planning for village development are the leading tasks for promoting the effective implementation of rural revitalization strategic planning at the village level.The optimization of the space of villages and towns is the basis for the implementation of my country’s rural revitalization strategy and the construction of the pattern of rural revitalization.At this stage,it is difficult for land use control to achieve global spatial feedback in the "topdown" multi-level planning indicators,resulting in a significant reduction in the effectiveness of transmission and hierarchical control implemented at specific microsites and rural scales,which makes the village level The spatial land types and functions at the level cannot be precisely connected with the “blueprint” of the land and space planning at the city and county level.However,the classification of villages under the current rural revitalization strategy implementation plan is mostly based on the traditional development index evaluation method to determine the type and revitalization path,which makes the “bottom-up” rural space governance logic cannot be effectively traced back to the higher-level spatial organization system and In terms of geographical structure and function,this thesis focuses on the solution of these two problems.Fengxian County is located in the hinterland of the Qinling Mountains and the source of the Jialing River.It is a key ecological function area and an important node to ensure the water environmental quality and water ecological safety of the South-toNorth Water Diversion.In order to better protect the ecological environment,Fengxian’s traditional competitive industry mining industry has been under tremendous pressure,facing outstanding problems such as a single industrial structure,the entire scope of Qinling’s ecological environment protection,large differences in the distribution of agricultural production resources,and the contradiction between ecological protection and residents’ livelihoods.Therefore,Fengxian is more urgent in the overall management and revitalization of rural space.In the process of implementing the rural revitalization strategy,how to coordinate the promotion of the relationship between industrial development and ecological environmental protection,quickly cultivate and guide the development of new industries such as characteristic industries and tourism,make precise efforts to address the crux of the problem,break through the barriers to the flow of elements,and restructure the space Governance to promote structural optimization and resource allocation has become an urgent need to achieve high-quality regional development.Therefore,from the perspectives of geography and planning,this research is guided by the theory of man-land relationship geographic system,the theory of resource and environment carrying capacity,the theory of three-generation functions,the theory of rural geographic system,and the theory of urban and rural organisms to construct the development of villages and towns in Fengxian County.Research framework;based on field research,questionnaire survey,third national land survey data,statistical yearbooks and manuals,planning materials,Auto Navi POI hotspot data and website crawling Information and other information obtained comprehensive and detailed village-level data in Fengxian County;used Arc GIS spatial analysis,landscape pattern index model,analytic hierarchy process,entropy method model,rank scale rule and quartile potential factor evaluation method to carry out quantitative research;Relying on the spatial pattern relationship of “double evaluation”,“Production-Living-Ecological”space and “three districts and three lines”,according to the research ideas of “elementstructure-function” and “partition and then classification” development guidelines,the resources and environment carrying capacity of Feng County are clarified.The ability level and the appropriate scale of urban,agricultural,and ecological spaces have been evaluated for the comprehensive development level and agglomeration capacity of the“Production-Living-Ecological” space at the town and village scales.Based on the characteristics of the district and classification pattern of 66 administrative villages in the county,the spatial optimization strategy and classification development path of Fengxian County are proposed.The results show that:(1)In terms of ecological space,the overall service function of the ecosystem of Fengxian County is relatively good.Among them,the important functions of biodiversity,water conservation and soil and water conservation are the most prominent.In addition,the Qinling Mountains have a prominent position in ecological environment protection,and the ecological location pattern is absolutely dominant;agriculture In terms of suitability,the area of arable land accounts for 5.42%,and the quality of arable land in Fengxian County is relatively low,most of which belong to low-grade lands.The slope limitation is the dominant limiting factor in Fengxian County.The overall level of agricultural suitability is low,but there is no obvious shortcoming factor restricting agricultural development.Although the area is limited,the carrying scale is moderate.The overall evaluation grades of arable land fertility in Fengxian County are generally at a weaker level.Among them,the third-class lands have the most extensive area,the fourth-class and fifth-class lands are scattered in a larger area,and the firstclass and second-class lands are more concentrated in the Jialing River and Xiaoyu River,Wangyu River,Chedao River and other watersheds;in terms of urban suitability,restricted by geological disasters and industrial transformation,the carrying scale of cities and towns is relatively limited,and the suitable space area is not large.(2)The difference in the comprehensive development level of the town-level“Production-Living-Ecological” space is not very significant.The top three comprehensive development levels are Liufengguan Town,Pingkan Town and Honghuapu Town,and the comprehensive development of Shuangshipu Town and Hepingmu Town.The lowest level.Among them,the development level of production space is between 0.031-0.030,and the difference is not large,indicating that the various villages and towns in Fengxian have not been able to widen a large gap in resource elements,industrial location and spatial attributes,but the spatial differences in the two types of indicators of life and ecology are different.The quality is very significant.The evaluation results of the development level of life and ecology are between 0.015-0.009 and 0.055-0.048,indicating that the various villages and towns in Fengxian County have relatively high heterogeneity in terms of life quality,social services,living space attributes,and ecological environment.It can be seen from the characteristics of the data that the overall rural space of Fengxian County cannot restrict the coordinated development of the “three types of spaces” through high-level mutual balance and lowlevel mutual restraint.Space,production space and ecological space each have their own characteristics.In terms of focusing on building and tapping advantages,improving the weak space factor is more in line with the rural development path of Fengxian County than the balanced relationship between the quantification of the three types of space and the balance of constraints.(3)There are obvious spatial differences in the agglomeration capacity of factors at the village scale.In the township-scale “Production-Living-Ecological” space,the ecological space dominates and the difference in comprehensive development levels is small.The village-scale element agglomeration capacity presents a basic pattern of relative agglomeration in general and relative dispersion in parts.Although the agglomeration capacity of the 66 administrative villages differs significantly,the distribution is not scattered.Among them,the population factor is dominated by net outflow,the development foundation of agricultural factors is relatively good,and the development level and scale of non-agricultural factors are not strong.The village rankscale distribution is relatively concentrated,the middle rank villages are the most prominent,the high rank ranks are more obvious than the low rank ranks,and the spatial polarization of the elements shows that the ability of diffusion is stronger than the capacity of agglomeration.(4)Combining the “three regions and three lines” pattern and the “comprehensive potential advantage degree” of the four types of factors: food production advantage degree,characteristic industry advantage degree,cultural tourism potential degree,and quality of life guarantee advantage degree,adopt “zoning first,then classification” The model is comprehensively subdivided into 12 categories of villages: ecologically sensitive and fragile maintenance category,ecological resource moderate development category,ecological protection and livability improvement category,ecological protection rural industry category,spatial activation diversified development category,rural industry characteristic shaping category,urban and rural Linkage and threeindustry integration category,advantageous agricultural feature shaping category,leisure agricultural equipment improvement category,livable and tourist potential tapping category,urban agglomeration center development category,and industrial integration sub-center collaboration category.It can be seen from the number of classifications of 66 administrative villages that the proportion of rural revitalization and development in Fengxian County is the largest,of which the number of urban-rural linkage tertiary industry integration is the largest.Advantages in agricultural space The shaping of agricultural characteristics and the promotion of leisure agricultural equipment have become important focal points for future rural development in Fengxian County.Urban space focuses on the coordination of industrial integration and subcenters,and ecological space focuses on spatial activation and diversified development.(5)The urban production space is developing towards characteristic and highquality products.The agricultural space is developing and transforming towards practicality and linkage.The production and living spaces are upgraded to urban-rural integration,industrial collaboration and residential collaboration.Accelerating industrial transformation and upgrading,cultivating and expanding characteristic industries,and promoting industrial spatial agglomeration are the keys to the development of villages and towns in Fengxian County.The enhancement of the functional value of space and the integration of the tertiary industries are the main path for the optimization of the“Production-Living-Ecological” spatial pattern,combining the potential of industrial advantages,the spatial layout of the agricultural economy,and the location level to effectively refine the functional characteristics and development priorities of the village.Innovatively develop green growth space,develop the capitalization of ecological land assets,and explore the forest carbon sink and carbon sink trading market.Deepen the integrated development of the tourism industry and improve the core competitiveness of tourism.To sum up,this study first conducted a spatial quantitative evaluation of Fengxian’s resource carrying capacity and urban,agricultural,and ecological space suitability levels based on the “dual evaluation” guidelines.The quasi space and the“Production-Living-Ecological” space are connected by land grid patches;then,starting from the functional.“Production-Living-Ecological” space,the comprehensive development level and agglomeration capacity at the town and village scales are refined respectively;in order to represent the development of villages in Fengxian County Characteristically,this study selected the four-element potential advantage factors that fit Fengxian County to quantitatively analyze the development potential of each village.Based on the spatial layer results of the above three aspects,the spatial analysis and calculation,logical overlay and zoning statistics are carried out in sequence according to the village-level units,and finally the zoning classification pattern of Fengxian villages is determined,with a view to coordinating the spatial development and optimization of Fengxian villages.The accurate control of the path provides a certain reference value. |
