摘    要:基于山东省1987~2003年统计资料和土地详查与变更调查数据,研究揭示了山东省近17年来土地利用结构信息熵的时空变化,并在此基础上进一步探讨了土地利用结构动态变化的驱动机制。结果表明:17年来,山东省土地利用结构信息熵的变化经历了增加→减少→缓慢增加的变化过程,总体趋势是各土地利用类型的面积占土地总面积的比例差别逐渐缩小,土地利用结构的均质性逐渐增强;土地利用结构的信息熵具有空间分异规律,从东部沿海向西部内陆递减,总体而言,东部半岛丘陵区的信息熵值>中南部山地丘陵区>西部、北部平原区;自然因素、人口变化、经济因素和政策调控等是影响土地利用结构动态变化的主要驱动因子。

关 键 词:土地利用结构  动态变化  驱动力  信息熵  山东省

Abstract:According to statistical and detailed survey data of land use from 1987 to 2003,the spatial-temporal change of land-use structure in Shandong Province during the last 17 years were analyzed,based on which,the driving force of information entropy wre discussed in this article.The results showed: ① the change of information entropy undergent the process from increase to decrease to gently increase in Shandong during the past 17 years.The total trend was that the difference among area proportion of every land use type accounting for the total land area gradually was reduced and the symmetrical degree of land-use structure was gradually built;② there was a spatial distribution law for information entropy of land-use structure and the numerical value was progressively decreased from the coastal to inland in Shandong Province.The order of information entropy value was: the Eastern Byland hill region>the Middle-south mountain and hill region>the Western and North plain region and ③the driving forces affecting the spatial-temporal change of information entropy value of land-use structure in Shandong were natural factor,population change,economic factor and policy adjustment.
Keywords:Land-use structure  Dynamic change  Driving force  Information entropy  Shandong Province
