SPATIAL-TEMPORAL EVOLUTION CHARACTERISTICS OF RURAL LAND DEPENDENCE FROM THE PERSPECTIVE OF MAN-LAND RELATIONSHIP
In view of the outflow of young people,the increase of aging degree and the decline of rural areas in rural areas,based on the perspective of man-land relationship,this paper takes rural land dependence as a quantitative index of rural man-land relationship,and explores its spatial and temporal evolution characteristics and influencing factors,so as to provide references for rural revitalization and development.On the basis of defining the concept of rural land dependence,an evaluation index system of rural land dependence was constructed,and the entropy weight method was used to quantitatively measure the level of rural land dependence of 30 provincial administrative units in China from 2006 to 2020.Based on GIS spatial analysis,gravity center evolution model and Spearman correlation coefficient,the spatial and temporal pattern evolution characteristics of land dependence in China were discussed.The results were showed as follows.(1)From the time series evolution,since 2006,the level of rural land dependence in China had been decreasing,and the difference of sub-item dependence was economic dependence>population dependence>spatial dependence.(2)From the spatial pattern,during the study period,the spatial distribution of rural land dependence in China showed the regional difference characteristics of"high in the southwest and low in the eastern coast".Among them,the spatial distribution of high dependence changed from concentration to discrete distribution,and the spatial distribution of low dependence changed from dispersion to concentration.(3)As for the evolution of the center of gravity,from 2006 to 2020,the center of gravity of rural land dependence moved northward from Xichuan county,Nanyang city,Henan province to Lushi county,Sanmenxia city,Henan province,and moved from the south where water and soil resources were relatively matched to the north where water and soil resources did not match.(4)From the correlation of influencing factors,land dependence was negatively correlated with regional economic development level and per capita net income of farmers,and positively correlated with per capita rural area.The correlation degree was showed as follows,regional economic development level>per capita net income of farmers>per capita rural area.In summary,with the development of economy and the advancement of urbanization,the dependence of population on land in rural areas is decreasing,especially in the eastern developed coastal areas.The contradiction between more people and less land has gradually changed to"less people and more land",and the allocation and utilization efficiency of rural land resources may be reduced.Population dependence and economic dependence are showing an overall downward trend,reflecting the reduction of the attractiveness of rural land to the population,which further confirms the problem of rural labor loss.The loss of labor will naturally affect the development of rural economy.Therefore,the research suggests that in the process of rural revitalization,it should focus on rural industries,properly deal with the problem of"man-land-money"in rural areas,pay attention to new business entities,attract excellent talents for rural revitalization,and promote rural economic development and narrow the gap between urban and rural areas to help rural revitalization.
