山东半岛土地集约利用评价及时空分异特征

Evaluation on Concentrated Land Use and Spatial-temporal Difference Characteristics of Shandong Peninsula

遵循系统性、科学性、前瞻性、动态性等原则,结合山东半岛城市群区域发展实际,从土地利用强度、投入、效益和生态环境出发构建了区域城市土地集约利用评价指标体系,采用均方差权值法对山东半岛城市群土地集约利用水平进行了综合评价,对其时空分异特征进行了深入、系统地研究。结果表明:2005年以来,山东半岛城市群土地集约利用综合指数总体呈下降趋势,2010年略有回升;土地集约利用水平区域差异明显,青岛、威海集约利用程度最高,潍坊、烟台、东营次之,日照、济南、淄博利用水平最低。

Combining with actual development of Shandong peninsula,from the aspect of intensity,investment,benefit and the ecological environment of land unilization,assessment system of concentrated land use in regional urbans has been set up.By using the mean-square deviation weights method,comprehensive evaluation on the level of intensive land use in the urban agglomeration of Shandong peninsula has been carried out,and its spatial-temporal differentiation characteristics have been studied as well.It is showed that the composite index of the intensive land use in the urban agglomeration in Shandong peninsula has been declining since 2005,and slightly rebounded in 2010.Regional differences of the level of intensive land use are obvious.The intensive utilization levels in Qingdao and Weihai are the highest,Weifang.Land use levels in Yantai and Dongying take the second place,while the are the lowest in Rizhao,Jinan and Zibo.
