| 摘 要： | 为了优化城乡用地结构和分布,需要了解其动态变化,信息熵的演变(1996-2003年)在一定程度上可以反映区域各类土地利用类型的动态演变规律,信息熵在空间上的分布可以反映区域土地的分布,因此利用信息熵对济南市城乡用地结构及分布进行研究.结果表明济南市城乡用地结构的有序性呈下降趋势,用地分布呈现由中部向外围有序性降低.

| Abstract: | It is necessary to know the dynamic change of urban and rural land use structure and distribution so as to optimize the structure and distribution.As the change of Shannon entropy can reflect to a certain degree the dynamic evolution laws of various land use, and the distribution of Shannon entropy can reflect land distribution, this paper uses Shannon entropy to study the structure and distribution of land use of Jinan City. The result indicates that the order of land use structure in Jinan has a tendency to decline, and the distribution of land use is decreased in order from the central part to the periphery. |
