| Countryside refers to the rural spatial regional system composed of areas outside the urban built-up areas,and its function depends on the characteristics of rural regional resources.Rapid urbanization and industrialization have intensified the flow of rural regional factors.In order to meet the needs of rural development and production and living services of residents,different spatial regions have gradually changed from single food supply and ecological resource functions to development directions containing different functions of production,life,economy,society,culture and ecology.However,climate change,food security,rural resources and environment pressure and ecological problems,urban-rural development imbalance and so on hinder the multi-functional development of rural areas.Shandong province,an important economic and agricultural province,is in a crucial period of changing old growth drivers in agriculture and making solid progress in rural reform.At the same time,the development of agriculture and rural areas in Shandong Province has also exposed many problems,such as the quality of agricultural supply is not high,the rural environment and ecological problems are prominent,the gap between urban and rural infrastructure and public service level is large,obviously restricted the overall development of rural areas in Shandong province.Based on this,it is of great theoretical and practical significance to carry out rural regional function evaluation,spatial differentiation,coupling coordination and dysfunction diagnosis in Shandong Province,which is of great significance to build the model of rural revitalization in Qilu and promote the application and sustainable development of rural economic and social construction.At present,the research on rural regional function has achieved fruitful results in theoretical,methodological and empirical research,but most of the domestic research uses the traditional coupling coordination degree model,and the contribution coefficient of the subjective setting subsystem is equal,which is different from the facts,and the model is a static model,which cannot reflect the change trend of coupling coordination relationship.In addition,the spatial zoning of rural regional functions is mainly based on the principle of region-led functional zoning,and there is a lack of in-depth discussion on hindering functions.Therefore,137 administrative units in Shandong Province were selected in this study,2005,2010,2015 and2020 were selected as the research time nodes,and 21 indicators such as rural population density,average grain yield and per capita arable land area in rural areas were selected based on the multi-factor comprehensive evaluation method to construct a multi-functional evaluation index system for rural areas.On the basis of analyzing the functional spatial pattern of rural areas,static and dynamic coupling coordination models are used to clarify the spatiotemporal differentiation characteristics and dynamic change trends of the coupling degree and coupling coordination degree of life,production and ecological functions.According to the spatial zoning principle of "current situation" + "trend",different spatial divisions are carried out for rural regional functions;By constructing a multi-functional disorder diagnosis model in rural areas,the intensity and impact range of the dysfunction function in different spatial divisions are quantified,diversified optimization measures are explored,and differentiated improvement strategies are formulated.The main research contents of this paper are as follows:(1)Rural regional functions in Shandong Province showed obvious spatial heterogeneity.From 2005 to 2020,the comprehensive evaluation index of rural regional function showed an increasing trend,with production function > living function > ecological function.The space center of gravity moves slightly to the southwest as a whole.ClassⅠwas distributed in central Shandong and the northeast coastal areas,and Class Ⅲ was scattered in southwest Shandong and northwest Shandong.Rural regional functional agglomeration has been further enhanced.From the perspective of different rural regional functions,the overall development of production functions is relatively backward,showing the spatial distribution characteristics of "high-lowhigh" in the direction of "southeast to northwest",and the spatial agglomeration is somewhat reduced.The life function developed relatively fast.TheⅠ-level districts were distributed in clusters in central Shandong,northeast Shandong and a small part of southern Shandong,with weak spatial correlation,and only LL type showed a certain spatial agglomeration.The overall development state of ecological function was the worst,and more than 79% of the districts and counties showed negative growth,among which the number of grade Ⅲ districts was the most,and they distributed in clumps in some areas of southwest and northwest Shandong,showing strong spatial agglomeration.(2)From 2005 to 2020,the functional coupling degree of rural areas in Shandong Province showed the quantitative distribution characteristics of high coupling type > run-in type >antagonistic type.The static coupling coordination degree showed a trend of steady increase,and the coupling coordination relationship showed moderate coordination development,showing a spatial pattern of high in the east and low in the west.The "production-life" function coupling coordination relationship develops into moderate coordination,which is manifested by the spatial distribution characteristics of decreasing gradually from southeast to northwest."Production-ecology" and "life-ecology" show basic coordinated development,and the coupling coordination types between different functions are mainly mild discoordination.The type of dynamic coupling coordination is mainly negative coupling,which is distributed in central Shandong,northern Shandong and part of southwest Shandong.Among them,"production-life","production-ecology" and "life-ecology" are mainly negative dynamic coupling types,most of which are concentrated in the north of Shandong Province,the northwest of Shandong Province and the eastern edge of central Shandong Province.From the perspective of the dynamic coupling characteristics of rural areas,the single administrative function(ecological lag development)is mainly distributed in the northwest part of Shandong Province and most of the central part of Shandong Province.Single-function leading development(life-leading development)takes the second place,and is evenly distributed around counties with singlefunction lagging development.(3)Rural regional zoning in Shandong Province showed obvious spatial differentiation,which was divided into four different functional spatial zoning.The priority development areas showed low static and dynamic coupling coordination degree,and were distributed in clusters in western Shandong,western southern Shandong and a small part of central Shandong.The obstacle functions in this area were residential life,living security,non-agricultural production and environmental compensation.The dominant development area is characterized by low static coupling coordination degree,which is distributed in blockers in the northwest and southwest of Shandong Province and a few districts and counties in Yantai of eastern Shandong Province.The obstacle functions are living,living security,non-agricultural production and environmental compensation.The transformation development area showed a low dynamic coupling degree of coordination,and distributed in the junction of central Shandong Province,western Shandong Province and northern Shandong Province in a point-and-block manner.The obstacles were manifested as living,living security,non-agricultural production and environmental compensation.The balanced development area showed high static and dynamic coupling coordination degree,distributed in the provincial capital and most areas of Jiaodong,and the main obstacle functions were residential life,living security,agricultural production and nonagricultural production. |
