土地利用结构信息熵变化与社会经济发展的相关性分析——以新疆阿克苏市为例

The Change of Land Use Information Entropy and Its Correlation with the Social and Economic Development in Akesu City

基于阿克苏市1996～2008年的土地利用分类数据,运用土地利用结构信息熵测算模型分析阿克苏市土地利用结构信息熵动态变化,定量分析阿克苏市土地利用结构信息熵变化与社会经济发展的相关性。结果表明:①1996～2008年,阿克苏市土地利用结构信息熵总体呈持续上升的变化趋势,至2008年土地利用结构信息熵为0.977 4,比1996年增加了0.123 7。交通用地、耕地、居民点工矿用地、园地等土地利用类型面积所占比例的高低是影响阿克苏市土地利用结构信息熵值的主要因素。②社会经济发展与土地利用变化之间表现出复杂的相互作用关系,经济发展方式很大程度上决定了土地利用结构变化,导致了土地利用结构信息熵的迅速变化。其中以制造业、建筑业为主的第二产业与土地利用结构变化相关系数最大,为0.988,对土地利用结构的变化影响最大。

According to land use classification data in Akesu City during 1996-2008,using land use structure information entropy,the dynamic change of land use structure information entropy was analyzed.The correlation between land use structure information entropy variation and social economic development in Akesu City was quantitatively analyzed.The results showed that during 1996-2008,land use information entropy is tend to rise,0.977 4 in 2008,increase 0.123 7 than that in 1996.The proportion of farm land,residential and industrial land,garden plot with traffic is the main factor that influence the land use information entropy of Akesu City.It is shown a complex relationship between the development of social economic development and the land use change performance.The way of economic development determines the structure of land use change largely,and leading to the rapid change of land use information entropy.The second industry influences the change of land use heavily,namely 0.988,the highest correlation coefficient with land use information entropy.
