| 摘 要： | 根据生态位理论,用城市综合发展水平和生态位宽度来反映各城市对所在群落中的资源占有和利用程度,通过聚类分析和生态系统结构的划分对河西走廊20个县域城市的竞合关系进行了评价。结论表明:2001—2013年间,河西走廊各城市综合发展水平均有不同程度的提高,城市生态位也表现出不同程度的升降,综合发展水平值与生态位宽度呈高度正相关关系,说明各城市对资源的占有和利用程度联系密切,相辅相成。嘉峪关市和金川区生态位始终位于河西走廊20个县域城市前列,为第Ⅰ类城市,凉州区、肃州区和甘州区为第Ⅱ类城市,阿克塞县、玉门市、敦煌市和肃北县为第Ⅲ类城市,其余11个城市为第Ⅳ类。在此基础上,结合生态位错位、扩充、协同发展等理论,根据城市生态系统结构提出了相对应的基本竞合发展策略。
