Evaluation And Spatial-temporal Pattern On Rurality And Analysis Of Its Driving Factors In Deyang

As an important part of urban and rural systems,rural area plays an important role in the development of regional social economy.In the background of reverse urbanization in developed countries,the development of rural areas in our country still lags behind the city and is in the urban-rural dualistic structure for a long time.Improving the level of rural development is an important task for China to realize rural revitalization and urban-rural integration.Deyang,as an important part of Chengdemian Economic Zone,has the highest level of economy development in the whole province,but its urban-rural dualistic structure exists for a long time,the internal township development level is different and the rural revitalization road is difficult.Studying the level of rural development in Deyang and its influencing factors has significant theoretical and practical significance for achieving urban-rural coordination and rural revitalization.Based on the relevant data and actual situation of the 120 townships in Deyang in 2000-2015,this paper calculated the rural index,analyzed the temporal and spatial evolution law,and used GWR model to estimate the influence factors of the difference and change of Deyang rurality index,and finally selected the typical township in the study area to analyze it,and summarized their development experience or make suggestions.The main conclusions were as follows:(1)Timing change,In 2000-2015,the Deyang rurality index showed an overall decline of three stages: slow decline-steady development-rapid descent,indicating that Deyang village was in a state of constant development.Most villages and towns in the study period showed a continuous downward trend,a small number of towns showed a downward trend of fluctuations,the rural index has been to low value,the weak rural index of rural areas increased,and the differences in rural areas within the region have continued to increase.(2)Space evolution,the weak rural areas were mainly distributed in the central plains and were expanding;the weaker villages and stronger villages were centered on the central plains,the weaker rural towns were increasing,and the stronger rural villages and towns were reduced.;strong rural areas were mainly distributed in the northwest The area of the mountainous area was large and decreasing.Deyang rural village index showed strong spatial autocorrelation,and spatial agglomeration showed an increasing trend.HH and LL were the main types of agglomeration.Among them,HH agglomeration was mainly distributed in the northwest and southeast,and the northwestern region had larger agglomeration area.,LL agglomeration was mainly distributed in the central region,and its area showed a growing trend.(3)Influencing factors,the correlation coefficient and direction of influence of different influencing factors at different time points for different townships and townships were different.The central towns had the greatest influence on the spatial and temporal changes and spatial differences of the rural index,and the road network had less influence.The rural index was positively correlated with the topographic index,the distance between central towns and the quality of cultivated land,and negatively correlated with the growth of road network density.(4)Typical township,the development of townships with different levels of development and different development conditions is inconsistent.Five towns were selected as typical towns,and their development experience or deficiencies were summarized according to different development situations,and suggestions were made to provide reference for rural development.
