中文摘要：
利用信息熵原理,采用1997～2005年土地利用变更调查数据,从时序与空间两个角度对湖北省土地利用结构信息熵的分异规律及其成因进行了分析。结果表明,湖北省1997～2005年土地利用结构信息熵呈现出先增加后收敛的趋势,土地利用结构信息熵的高低与土地管理政策特别是耕地保护政策的松严密切相关;湖北省土地利用结构均衡度在空间上表现出区域分异规律,土地利用结构均衡度的高低受区域自然条件、社会经济发展水平的影响。
英文摘要：
In this paper, based on the view of time sequence and space difference, differentiation law of information entropy in land use structure in Hubei province was analysed by means of information entropy according to the data of land use change survey from 1997 to 2005. Several conclusions can be drawn from the study. Firstly, land using structure information entropy of Hubei province was increasing first and reducing then from 1997 to 2005 which was directly bound up with the policy of land management especially the policy of cultivated land protection. Secondly, the equilibrium degree in land use structure shares a space difference which is caused by the level of regional natural conditions and socioeconomic growth.
