摘要
为分析与掌握湖北省耕地资源的时空分布及变化特征,实现耕地可持续利用与缓和人地矛盾,以湖北省的耕地为研究对象,以2011—2018年的耕地数据和相关统计年鉴数据为基础,选取耕地相对变化率指标,探究耕地数量的动态变化及空间差异,并运用灰色关联分析法研究耕地数量变化的驱动力.结果表明:研究期内全省耕地数量总体减少,人均耕地占有量呈逐步下降趋势;全省的耕地数量变化具有明显空间差异性,根据耕地相对变化率将湖北省分为耕地增长区、耕地缓慢减少区、耕地快速减少区和耕地急速减少区;人口压力、农业结构调整与技术水平、经济发展因素是影响湖北省耕地数量变化的主要驱动力.
In order to analyze and grasp the spatial-temporal distribution and change characteristics of cultivated land resources in Hubei Province,to realize the sustainable use of cultivated land and ease the contradiction between human and land,the cultivated land in Hubei Province is taken as the research object,based on the arable land data and relevant statistical yearbook data from 2011 to 2018,the relative change rate of cultivated land is selected to explore the dynamic changes and spatial differences of cultivated land,and the gray correlation analysis method is used to study the driving force of cultivated land quantity.The results show that during the study period,the total amount of cultivated land in the whole province decreased,and the per capita cultivated land occupation showed a gradual downward trend;the number of cultivated land in the province has obvious spatial differences,according to the relative change rate of cultivated land,Hubei Province is divided into cultivated land growth area,slowly cultivated land decrease area,quickly cultivated land decrease area and rapidly cultivated land decrease area;population pressure,agricultural structure adjustment and technological level,economic development are the main driving forces that affect the changes of cultivated land quantity in Hubei Province.
