城市土地集约利用时空差异分析——以济南都市圈为例

ANALYSIS OF SPATIAL-TEMPORAL DIFFERENCE OF REGIONAL URBAN LAND INTENSIVE UTILIZATION---A CASE STUDY OF JINAN METROPOLITAN AREA

本文结合山东省新建规划济南都市圈7个城市的实际状况，以山东省地市统计年鉴的相关数据为基础，从“经济—社会—生态—可持续趋势”角度构建了城市土地集约利用评价指标体系，采用多因素综合评价法、层次分析法对区域内城市土地集约利用水平进行了综合评价，分析土地集约利用水平在时间上的变动情况和区域间差异，为促进区域内土地资源的可持续利用、转变土地利用方式提供建议。研究表明：2006-2012年济南都市圈城市土地投入、经济产出不断增强，土地生态质量也有所提高，土地集约利用水平呈上升趋势；各市土地集约利用水平上升轨迹有所差异，主要分为波动上升型、突变型、先升后降型；区域间城市土地集约利用水平差异明显，总体上土地集约水平东部城市高于西部城市；区域内城市土地集约利用趋势较差，人口与用地弹性系数、GDP与用地弹性系数较小，在城市面积扩张的同时必须进一步加强城市土地投入强度和提高土地经济效益产出。

The paper tried to explore the evaluation system of regional urban land intensive utilization from the＆quot;economic-social -ecological sustainable development＆quot;point.Based on the actual situation and relevant data from statistical yearbook of Shandong Province,using the multi -factor comprehensive evaluation and analytic hierarchy process method,the paper made comprehensive evaluation of regional urban land intensive utilization level of seven cities of Jinan metropolitan,analyzed the changes of land intensive level in time and the regional differences,in order to provide suggestions for the sustainable utilization of land resources in the area and changing land use pattern.The results showed：there existed a general rising of the land intensive utilization in the cities of Jinan Metropolitan Region from 2006 to 2012 except Dezhou City showing a fluctuating decline.The differences of urban land intensive utilization are significant in Jinan metropolitan cities.Jinan City,being the capital of Shandong Province and the portal of Jinan Metropolitan Region,did not make the highest urban land intensive utilization,just reaching the relatively intensive level.Urban land intensive use in Jinan Metropolitan Region is poor at present,and further urban land investment should be intensified to improve land economic output.
