| 摘 要： | 通过一系列的实证资料,确定了区域城市化水平评价指标体系。运用主成分分析方法计算了兰州市1994-2004年城市化水平,并对兰州市耕地面积与城市化水平的关系进行了相关分析,发现兰州市城市化水平与耕地面积之间具有显著的线性相关关系,在此基础上建立了二者之间的线性回归模型:Y=1.506-0.04X。最后提出了解决加快城市化进程与耕地面积减少矛盾的几点建议。

| Abstract: | Based on a series of real example materials,theappraising index system to estimateurbanization level was set up.Using principal component analysis,the urbanizationlevels in Lanzhou City during the periodof 1994 -2004 were calculated and the relationship betweenurbanization leveland the cultivated land was analyzed.It was found that the urbanization level and cultivated land had notable linear relation in Lanzhou,the linear regression model(Y=1.506-0.04X) was made.At the end,the different specific countermeasures were proposed. |
