摘要
为给保定市土地利用结构调整、土地资源优化配置和可持续利用提供参考,借助信息熵理论,对保定市土地利用结构信息熵的动态变化规律及其空间分布规律进行分析,并运用灰色关联分析了其变化的驱动力。结果表明,受地理位置和社会条件的影响与制约,保定市各县(市)土地利用结构存在一定的差异,第三产业所占比重和城镇化率对土地利用信息熵的关联度最大。
To provide certain references for adjusting land use structure,optimizing the allocation and sustainable utilization of land resources in Baoding City,the dynamic changes of land use structure and its spatial distribution were analyzed with information entropy theory,and their driving forces were studied using grey relative degree analysis.The results showed that there were certain differences of land use structures in each county of Baoding City due to the influence of geography and social conditions.The tertiary industry accounts for the proportion and the urbanization rate were the biggest to the land utilization information entropy interrelatedness.
