摘　　要：基于生态足迹模型,对甘肃南部地质灾害多发区的舟曲县进行生态足迹和生态承载力分析.舟曲县2012年人均生态足迹均衡值为1.885 7 ha/人,而人均生态承载力均衡值为1.020 2 ha/人,整体处于生态赤字状态.其中草地产生生态赤字最为严重,水域和林地处于生态盈余.舟曲县有6乡呈现生态赤字,处于生态赤字的乡镇体现了对区域内白龙江流域水资源利用的依赖性.运用生态足迹模型分析舟曲县各乡镇生态承载能力,可为进一步开展定量化区域生态风险评估和流域的生态环境治理提供科学依据.A spatial difference analysis was carried out of the ecological carrying capacity in Zhouqu City based on the ecological footprints method and the results indicated that the ecological footprint of the Zhouqu was 1.885 7 ha/pre in 2012 and the ecological carrying capacity was 1.020 2 ha/pre. The study areas have been in conditions of ecological deficit, of which the grass land was in the most serious situation, while the forest land and the watershed have been kept on abundance level. Six counties remained in ecological deficit conditions because of their excessively dependent on the water resources from the Bai-long River. This study provides a scientific basis for the overall planning of land use and sustainable development in Zhouqu County.
