摘 要:分析土地利用结构时空变化是研究区域土地利用优化配置的重要途径之一。基于信息熵理论,以河北省武安市为例,对1996—2006年的土地利用结构信息熵变化以及2006年各乡(镇)信息熵差异进行研究,同时运用主成分分析法对信息熵变化的驱动力进行分析。结果表明,武安市土地利用结构信息熵持续增长,土地利用结构均衡度较高;2006年各乡镇信息熵差异较大,可划分成3种类型区;经济因素和人口流动因素是信息熵变化主要驱动力。Analyzing temporal - spatial changes of land - use structure was one of the important ways to study optimized deploy of the regional land - use. Based on the information entropy theory, set Wu'an City of Hebei Province as an example, this paper studied the dynamic changes from 1996 to 2006 as well as the spatial diversity of all villages and towns in 2006 in the information entropy of land - use structure in Wu' an,and used the principal component analysis to study qualitatively the driving forces of changes in information entropy. The results showed that the information entropy was in a state of sustained growth,and the equilibrium degree of land- use structure was relatively high in Wu' an. The diversity was quite large on the information entropy in villages and towns, and based on the information entropy villages and towns could be divided into three types. The economic factor and the factor of population mobility were the main driving forces of the changes in the information entropy.
