Study On The Evolution And Influencing Factors Of Rural Regional Function In Guangxi

With the continuous promotion of urbanization and industrialization,the interaction of social and economic factors between urban and rural areas has been enhanced,and the relationship between people and land has been drastically changed,and the geographical functions of rural areas have become increasingly diversified and complicated.At present,the strategic focus of China’s agricultural work is shifting from poverty eradication to the comprehensive implementation of rural revitalization,and the study of rural regional functions can provide important support for the classification and policy implementation of rural revitalization.Following the main research line of "spatial and temporal pattern evaluation,influence factor analysis,type identification and optimization strategy",the thesis constructs a countryside regional function evaluation index system based on three dimensions of agricultural production,living and ecological protection.With the help of socio-economic and land use data as well as technical methods such as the combination of empowerment method,Lorenz curve,spatial dislocation index,trade-off-synergy analysis and spatial econometric model,the paper analyzes the spatial and temporal evolution pattern of rural regional functions in Guangxi from 2000 to 2018,clarifies the interactive relationship among the functions of each dimension,analyzes the influencing factors of agricultural production function,living and living function and ecological security function in different periods,classifies The types of rural regional functions and the optimization strategies are proposed.The main findings of the study are as follows:(1)The spatial homogeneity of agricultural production function is weakening,while the spatial homogeneity of living and ecological security function is increasing.From the county level,the spatial pattern of agricultural production function "concentrated in the southeast and collapsed in the northwest" is strengthening,the spatial pattern of living and residential function "concentrated in the middle and decreasing at both ends" is emerging,and the spatial pattern of ecological security function "concentrated in the high mountains and collapsed in the basin" is stable;in terms of spatial correlation,the spatial aggregation of various functions is strengthening,and the spatial aggregation of agricultural production function is particularly prominent.(2)The trade-off-synergy relationship between the functions of rural areas in the region is obvious,with significant synergy between the functions of living and living and agricultural production,and significant trade-off between the functions of agricultural production/living and ecological security.At the county level,the intensity of the trade-off between agricultural production and living and residential functions continues to strengthen,and the spatial distribution pattern shows the replacement of high and low values;the intensity of the trade-off between agricultural production and ecological security functions tends to weaken,and the spatial distribution pattern maintains the characteristics of high in the middle and low in the two wings;the intensity of the trade-off between living and residential and ecological security functions continues to increase,and high in the middle and low in the two wings.The spatial distribution pattern is becoming clearer.(3)The influencing factors of rural agricultural production function change from endogenous factors to combined influence of endogenous and exogenous sources,but elevation and location conditions are always the main influencing factors;the influencing factors of rural living and residence function change from complex to simple,from combined influence of endogenous and exogenous sources to endogenous sources,but elevation and population concentration are always the main influencing factors;the main influencing factor of rural ecological security function is always population concentration.(4)The region’s rural areas are divided into seven functional types,including agricultural production type involving 5 counties,ecological security type involving 15 counties,agricultural production-living and living type involving 10 counties,agricultural production-ecological security type involving 7 counties,living and living-ecological security type involving 6 counties,11 counties in the synergistic development type,and 17 counties in the key enhancement type.Based on the results of the classification,we propose measures to optimize the regulation of differentiation from the perspective of key elements of land-industry-population that affect the rural regional system,taking into account the characteristics of each rural functional type area and its advantageous resources.
