摘　　要：选取甘肃省和武威市为参照区域,分析了1995—2009年民勤县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,土地资源是民勤县人口的主要承载资源;1995年以来民勤县相对土地资源承载力富余且较稳定,而相对经济资源承载力超载且上升缓慢,综合承载力处于轻度富余状态;民勤县正处于土地资源相对丰富、人口密度小、经济发展不足的阶段。The relative carrying capacity of land resources, relative carrying capacity of economic resources and synthetic carrying capacity of Minqin County was calculated, the evolution was described from 1995 to 2009, compared with Gansu Province and Wuwei City respectively. Thus conclusions were drawn： The land resources was the principal resources to support population in Minqin County;the relative carrying capacity of land resources kept in a stable trend and relative enough,however,the relative carrying capacity of economic resources symbolized a rising trend, stiU in overload condition,the synthetic carrying capacity of Minqin County was in the state of slight surplus. Minqin County went into the stage of relatively abundant of land resources,low population density and quite shortage of economic development from 1995.
