黄陵县土地利用结构信息熵及影响因素研究

Study on Information Entropy of Land Use Structure of Huangling County and Influencing Factor

基于信息熵理论,以黄陵县为例,通过信息熵和均衡度对2010—2014年黄陵县土地利用结构状况进行研究。并在此基础上,利用主成分分析法对影响信息熵的15个社会经济因素进行降维分析。结果表明,黄陵县土地利用信息熵呈现下降趋势,优势度不断上升,表明黄陵县土地利用在这5 a内总体向均衡方向发展,最终趋于稳定;影响因素提炼为两大方面:县域经济发展程度和产业结构变化。在上述研究的基础上,为黄陵县调整产业结构、协调人地关系、促进经济可持续发展,提出相关的发展建议。

The article summarizes the land use structure status of Huangling county in 2010-2014 based on information entropy theory and by taking Huangling county for an example and using information entropy and balance degree. Based on the summary, the dimension reduction analysis of 15 social and economic factors affecting information entropy is made using principal component analysis. The result shows that the land use information entropy of Huanglin county takes on a downtrend with rising degree of dominance. This indicates that the land use within five years develops toward balance as a whole, finally reaching a steady status and that there are two main influencing factors： county-scale economic development degree and industrial structure. Based on the above research, the article puts forward for Huanglin county related development recommendations for adjusting industrial structure, coordinating human-land relationship and promoting sustainable development of economy.
