徐州市土地利用结构变化的信息熵分析
首发时间:2010-12-17
摘要:以徐州市为例,从土地利用结构信息熵、均衡度、优势度的角度分析了2005-2009年土地利用结构变化,对徐州市土地利用结构信息熵的分异规律进行了分析。2008年省委、省政府出台《关于加快振兴徐州老工业基地的意见》,该意见落实的结果表明徐州市2005-2009年土地利用结构信息熵呈现出先增加后收敛的趋势,土地利用结构正不断向均衡状态发展,但其信息熵值同全国土地利用结构信息熵值相比依然较低,土地利用结构有待进一步合理调整。同时还提出了存在的问题并分析了导致这些问题的原因。此研究可以为徐州市未来土地利用结构调整、土地利用规划、土地的可持续发展提供理论借鉴。

Information entropy analysis of land use structure changes of Xuzhou
Abstract:Land use structure in Xuzhou was analyzed by means of land use structure information entropy , equilibrium and dominant from 2005 to 2009.It also analyzed the land use structure of information entropy differentiation rules in Xuzhou. Provincial committee and government issued " opinion on speeding up the revitalization of old industrial base of xuzhou " in 2008.Confirment result showed land use structure information entropy presented the trend of first increasement and then convergement .The land use structure is to keep equilibrium state but its information entropy is still lower than that of the national land use structure. The land use structure needs further reasonable adjustments.It also analyzed the existing problems and causes of these problems.The study can be used to provide theoretical reference for the adjustment of the future land use structure, land use planning and sustainable land use of Xuzhou.
Keywords: information entropy land use structure changes Xuzhou
