全运会对济南市城区土地利用变化的影响分析

2009年十一届全运会在济南市举办,为迎接全运会召开,济南市在城镇基础设施、体育场馆及相关配套方面进行了大量建设准备工作,这些准备大多涉及到土地利用的变化。为了揭示大型运动会对举办城市土地利用的影响,采用2003—2005年1∶10 000土地利用现状图作为数据源,以济南市城区为研究区,采用修正的动态度、开发度、耗减度等一系列指标对土地数量变化进行定量分析;采用信息熵对土地空间结构合理性进行研究。结果表明:济南市城区耕地、居民点及工矿用地、林地、未利用土地为土地利用变化的"热区",相互之间变化明显,其中耕地转移面积达到285.87km2,新增面积354.33km2,变化面积最大,交通设施用地动态度最高,为0.67;信息熵呈上升趋势,由1996年的1.77增加到2004年的1.835,空间结构总体呈现良性变化;经济发展是土地利用变化的内在动力,政府行为在一定程度上影响了土地利用的变化方向。该研究对其他举办大型运动会的城市及相关部门提供决策支持。

Influence of the Eleventh National Games on Land Use Change of Building Area in Ji’nan City

To meet the eleventh National Games’ needs of city infrastructure,stadium,ancillary facility,a lot of preparations were made,which resulted in land use change.This paper adopted present status map of land use from 2003 to 2005 as data resource and made use of a series of indices such as rectified dynamic degree of land use,development degree,depletion degree to analyze the quantitative change,at the same time,used information entropy to evaluate the spatial structure ration.Based on above analysis,we found that,firstly,cultivated land,residential land,mineral land,forest land,unused land were the ’hotpots’ of land use change,furthermore,they were of interaction,among which area of cultivated land transfer and newly added area respectively reached 285.87 km2 and 354.33 km2,respectively,and the dynamic degree of traffic land is 0.67,which is the highest in all kinds of land use;secondly,spatial patterns developed at a speed of stability and laid out a good change,all of these reflected positive response to economic inspiration and governmental macro control.Land use structure and spatial patterns has undergone large changes recently with the implementation of large sports meet.It’s significant to make scientific decision for government and relative administration sector to hold such a large sports meeting.
