| 摘 要： | 统计物理学用＂熵＂来表示分子不规则运动的程度,信息论中则用它来度量信息量,即一个系统越是有序,信息熵就越低。在对浙江省全省城镇土地调查数据汇总统计的基础上,运用信息熵的概念对复杂的城市土地利用结构进行详细的定量分析,用信息熵和均衡度值来说明城市土地利用的特点,利用方式的多样性和复杂性,并提出提高土地利用效益的工作建议。

| Abstract: | The entropy is used to indicate the degree of molecular random motion in Statistical Physics.While in information theory,it is to measure the amount of information,that is,the more ordered a system,the lower its entropy is.Based on aggregate statistic of the urban land survey data in Zhejiang province,this paper analyzed the land use composition using the concept of information entropy detailedly and quantificationally.Applying information entropy and equilibrium degree to explain the characteristics of land use,diversity and complexity of the use ways,it proposed to increase the efficiency of land use in conclusion. |

| Keywords: | information entropy equilibrium degree urban land survey land use structure application |
