摘　　要：采用相对资源承载力的方法,分析了甘肃省及各地区2001-2008年相对自然资源承载力、相对经济资源承载力和综合承载力及其变化过程。结果表明:甘肃省的承载状态自2003年以后处于富余状态,自然资源成为甘肃省主要承载资源;甘肃省超载最严重的是临夏,其次是陇南,然后依次是天水、甘南、定西、武威。省会兰州、嘉峪关、金昌、白银、酒泉的承载力都属于富余状态,张掖、平凉和庆阳除了极个别年份超载,大多数的承载力也都属于富余状态。The relative carrying capacity of natural re-sources,relative carrying of economic resources and synthetic carrying capacity of resources of Gan su Provinces from2001 to 2008 have been calculated,their evolutionary have been described.Thus conclusions were drawn： Load conditions in Gansu Province since 2003 was abundant,natural resources were as the main bearer resources in Gansu Province;Linxia was the most overloading region,followed by Longnan,then by Tianshui、Dingxi、Wuwei.The bearing capacity of Lanzhou、Jiayuguan、Kimchang、Silver and Jiuquan all were in the surplus state;Zhangye,Pingliang and Qingyang were overloading in addition to a very few years,but most years were in surplus state.
