Spatial heterogeneity of provincial rural-urban land conversion scale and effects of its influential factors
摘要
Abstract
As the inevitable process of land resources allocation in urbanization,large scale of rural-urban land conversion will bring enormous pressure on the protection of cultivated land and the sustainable use of land resources.Studying the spatial heterogeneity of rural-urban land conversion scale and effects of its influential factors is substantial for revealing the complexities of rural-urban land conversion and is helpful for regulating its scale via adopting differentiated and targeted control measures.This paper firstly explores the law of rural-urban land conversion scale of 31 provinces (autonomous regions and municipalities) in longitude and dimension direction.Based on that,it then analyzes the spatial heterogeneity of rural-urban land conversion scale on provincial scale by employing the global autocorrelation model and local autocorrelation model.Moreover,the spatial heterogeneity of effects of influential factors on rural-urban land conversion scale is studied.The results show that rural-urban land conversion scales of 31 provinces (autonomous regions and municipalities) display a steady upward trend in the horizontal direction and an inverted ‘ U’ type in latitude direction which means the scales reach the maximum value in provinces located in Central China and then decline gradually in provinces located in North and South China respectively.The provincial scales of agricultural land circulation in China are spatially related and the local auto correlation of provincial scales changes according to the regions they belong to which reflect the spatial heterogeneity.Four influential factors including total investment in fixed assets,residents' per capita disposable income,and quantity of farmland at the beginning of the year as well as the tertiary industry proportion have influences on rural-urban land conversion scale and the degree of influence varies with the spatial position.Besides the factor of total investment in fixed assets,all the other factors have great spatial heterogeneity of the degree of influence.Therefore,on the basis of considering spatial heterogeneity adequately,the differentiation and pertinence of land use planning as well as measures of regulation should be greatly improved in order to achieve the effective control of the rural-urban land conversion scale.关键词
