摘　　要：基于相关的统计年鉴,采用综合法对2000—2012年西藏农牧民的生态足迹与生态承载力进行分析.结果表明:研究期间,研究区农牧民生态状况均表现为生态盈余,但其盈余量呈逐年下降趋势;生态承载力由2000年的7.49 hm2下降到2012年的6.35 hm2,降幅达15.3%;生态足迹呈波动式逐渐增加趋势,由2000年的1.03 hm2增加到2012年的1.26 hm2.Based on relevant statistical yearbook and with an integrated method, the ecological foot- print and ecological carrying capacity of farmers and herdsmen during the period from 2000 to 2012 in Tibet Autonomous Region, China were studied. The results showed that the ecological status of farmers and herdsmen were in a surplus state during the study period, but the surplus amount exhib- ited a decreasing tendency. The ecological capacity decreased from 7.49 hm2 in 2000 to 6.35 hm2 in 2012, with a decrease of 15.3%, while the ecological footprint increased gradually from 1.03 hm2 in 2000 to 1.26 hm2 in 2012.
