苏北乡村转型与土地利用转型的耦合分析——以沛县为例

Coupling analysis of rural transformation and land use change in Northern Jiangsu:a case study of Peixian County

以沛县为例,分析了以传统农业为主的苏北乡村转型发展与乡村土地利用转型的耦合特征.研究表明：2006～2012年间,沛县乡村土地利用变化以生产用地向生活用地转变为主,具体体现在耕地-农村居民点用地、耕地-城镇用地的转变.计算结果表明,沛县全县乡村性指数较高,为0.06～0.70,其中〉0.50的有8个乡镇,〈0.20的只有2个.Spearman等级相关分析表明,耕地-农村居民点用地变化耦合系数与乡村性之间存在显著的正等级相关.

Taking Peixian County as an example,the coupling characteristics of the transformational development and the land use types are analyzed in the countryside in Northern Jiangsu.The results show that the land use types of Peixian County has given priority to living land instead of production land during 2006～2012.The turning is evidenced by farmland,rural residential area and urban land.Meanwhile,the county has a high rurality index of 0.06～0.70.The index of 8towns is bigger than 0.50,and that of 2towns is smaller than 0.20.The result of Spearman rank correlation analysis on the coupling index of rural land use changes and the rurality index shows that the coupling index is positive correlated with the turning from farmland to rural residential area.
