运用相关分析及回归分析法，对楚雄市2001年至2010年间城市化水平与反映生态环境变化的相关指标进行分析研究。结果表明，随着时间的推移，楚雄市城市化水平不断提高，城市化水平与建成区面积、城市用水量、水土流失面积、平均化肥施用量以及工业废气排放量呈显著正相关，与耕地面积呈显著负相关。通过回归分析发现，城市化水平与各环境指标的回归方程基本上为二次、三次函数及S型曲线。本研究除了二氧化氮含量变化符合库次涅茨曲线特征以外，其它指标变化并不符合该曲线特征。

With the method of correlation analysis, this paper studied the influences of urbanization on urban ecological envi-ronment in Chuxiong City from 2001 to 2010.The results showed that the urbanization level of Chuxiobg City improved continu-ously as time goes by.There were obvious positive correlations between urbanization and construction land area, urban water con-sumption, soil erosion, average chemical fertilizer application, industrial waste gas emission, while there was obvious negative correlation between urbanization and cultivated land area .The results of regression analysis showed that there were three kinds of regression equations about urbanization and environment indexes, including quadratic function, cubic equation and S type curve. The variation tendency of nitrogen dioxide content was in compliance with Kuznets Curve , while the trend of other indicators showed the different conclusions.
