基于信息熵的河津市土地利用结构时序变化及驱动力分析

以河津市1997—2008年土地利用变更调查数据及相关经济社会统计数据为基础,借助系统论中的信息熵、均衡度和优势度原理,分析了河津市土地利用结构的动态演变特征,并运用主成分与多元线性回归相结合的方法对土地利用结构变化的驱动力进行定量分析。结果表明,12 a来,河津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;人口经济发展以及产业结构调整是信息熵变化的主要驱动因子。

Analysis on Information Entropy of Land Use Structure Temporal Change and Its Driving Forces in Hejin City

Based on the land use change survey data and relevant economic and social data of Hejin city from 1997 to 2008,and supported by the theory of information entropy,equilibrium degree and dominance principle degree,characteristics of land use structure dynamic evolution of Hejin city was analyzed in this paper,and driving forces of land use structure change was quantitatively analyzed by using principal component and multiple linear regression analysis methods.The results showed that both information entropy of the land use structure and land use structure balance degree in Hejin city had grown continuously for 12 years;economic development,population growth and industrial structure adjustment were the main driving factors of information entropy change.
