基于信息熵的产业结构与土地利用结构优化的相关性分析——以呼和浩特市为例

Correlation Analysis of the Industrial Structure and Optimization of the Land Use Structure Based on Information Entropy—A Case Study of Hohhot

以呼和浩特市市域为研究区域,结合2009—2015年该市土地利用变更数据及产业经济相关的统计年鉴数据,采用信息熵模型研究法和线性回归分析法,对土地利用结构动态变化的信息熵及其与产业投资结构、产业产值结构的相关性进行分析。结果表明:第一、二、三产业投资水平与土地利用信息熵变化间的相关性依次为强负相关、弱负相关和强正相关,而三次产业产出水平与土地利用信息熵变动间的相关性依次表现为强负相关、强正相关和弱正相关。研究成果对提高区域土地利用结构的均质性和利用效率具有重要意义。

Taking the administrative region of Hohhot as the study area,combined with the change data of land use of Hohhot and the statistical data of industrial economy during 2009-2015,based on information entropy method and linear model research,we analyzed information entropy of land use structure dynamic change and its correlation with the structure of industrial investment and the structure of industrial output value. The results showed that: The correlation between the investment level of the first,second and third industry and the land use information entropy respectively was obvious negative correlation,obscure positive correlation and obvious positive correlation,meanwhile the correlation between the output benefit level of the three industries and the information entropy of regional land use respectively was obvious negative correlation,obvious positive correlation and obscure positive correlation. The research results are of great significance to improve the uniformity and efficiency of the regional land use structure.
