从土地利用结构、土地利用程度、土地产出水平、土地投入水平和土地可持续利用水平5个方面,选取15个评价指标,以东北地区34个地级城市为比较单元,建立原始数据矩阵,利用SPSS19.0统计分析软件进行主成分分析和聚类分析,分别对该34个城市土地集约利用程度进行评价,并划分为土地集约利用型、土地适度利用型、土地粗放利用型三种城市土地集约利用类型。结果表明,东北地区城市土地集约利用总体水平与发达地区相比存在较大差距,沈阳、大连、长春、哈尔滨等大城市和主要工业城市的土地集约利用水平较高,部分资源枯竭城市和基础薄弱、经济发展水平相对落后的城市土地利用粗放。

This essay selects fifteen evaluation indicators from five aspects of land use structure,land use degree,land output level,land input level and land sustainable use level,and sets up 34 city raw data matrices with 34 prefecture cities in Northeast China as comparison units.It carries on principal component analysis and cluster analysis using the statistical analysis software SPSS19.0,and respectively evaluates the intensive utilization degrees on 34 urban lands,and divides into three types of urban land intensive utilization as land intensive utilization type city,land moderate utilization type city,and land extensive utilization type city.The results show that there is a big gap on the overall level of the urban land intensive utilization between Northeast China and the developed areas.Land intensive utilization level of Shenyang,Dalian,Changchun,Harbin and other big cities,as well as major industrial cities,is higher;and cities with partial resource exhaustion and weak foundation in relatively backward economic development level are land extensive utilization.
