信息熵在深圳市土地利用结构分析和预测中的应用

Application of Information Entropy to Analysis and Prediction of the Land Use Structure in Shenzhen

利用信息熵的原理对深圳市改革前后若干年的土地利用结构和深圳市所属5个县区在同一时间的土地利用结构进行定量的计算分析,总结出:(1)深圳市土地利用的信息熵属于中等偏低,其土地系统的有序程度相对较高,土地利用较合理,土地利用结构信息熵随时间动态演变,同时具有空间分异性.(2)随着经济的快速发展,深圳市土地利用结构发生了巨大的变化,产业结构的调整必然引起信息熵值的改变.

By quantitatively calculating and analyzing by the fundamentals of information entropy the land use structure during several years before and after reform in five towns and districts in Shenzhen, this paper reaches two conclusions： First, the information entropy of land use in Shenzhen is at medium or a bit low level; its orderly degree of land system is relatively high, and its land use is relatively effective; the information entropy of land use structure develops by time and meanwhile shares a space difference. Second, with the high-speed development of economy, the land use structure changes a lot, and the adjustment of in dustrial structure is bound to vary the information entropy value. Therefore, the study of Shenzhen＇s land use can conversely optimize its industrial structure and predict the future trend of the land use.
