Research on spatial heterogeneity and influencing factors of intensive use of cultivated land in the Beibu Gulf urban agglomeration
摘要
Abstract
Scientific analysis of the spatial heterogeneity of intensive cultivated land use,and exploration of the influencing factors and their mechanism is of great practical significance for promoting intensive potential exploitation and efficient utilization of cultivated land resources.This study constructed a comprehensive evaluation framework based on two aspects:natural conditions and human factors.Principal component analysis,the Dagum Gini coefficient,and a geographically weighted regression model were used to empirically demonstrate the intensive use of cultivated land in the Beibu Gulf urban agglomeration in 2021.The index of cultivated land use intensification was 0.334,and the Gini coefficient was 0.183.The comprehensive level showed low intensity and no distinct spatial non-equilibrium characteristics,with the main sources being hypervariable density(50.33% )and the intra-provincial gap(45.60% ).The geographically weighted regression coefficients of temperature(0.491),proportion of agricultural sown area(0.273),elevation(0.165),and urban land intensification(0.146)were relatively large and positive,whereas the regression coefficients of precipitation(-0.440),urbanization rate(-0.207),and construction input intensity(-0.170)were relatively small and negative.All factors exhibited spatial non-stationarity.This study shows that the spatial heterogeneity of intensive cultivated land use in the Beibu Gulf urban agglomeration is manifested by spatial non-equilibrium of pattern and spatial non-stationarity of factors.The mechanism of action among multiple factors reflects that natural factors are the basis,with agricultural land intensification being positively promoted and non-agricultural land intensification negatively inhibited.Improving the intensity of urban land use,coordinating the scale of agricultural sowing,and quantifying the remuneration of cultivated land are the key points to improve the level of intensive use of cultivated land.关键词
