摘　　要：本文以西南岩溶地区清镇市为例,采用生态足迹的理论和模型对2005年清镇市区域生态足迹状况进行了测算和分析,并与不同区域进行比较。结果表明:①清镇市2005年的人均生态足迹为2.5440hm2,超过了它的人均生态承载力;②清镇市2005年人均生态赤字为2.1240hm2,表明清镇市处于一种不可持续的发展状态;③清镇市2005年万元GDP生态足迹为2.8139hm2,高于中国西部的平均水平,资源利用为粗放消耗型。针对清镇市生态赤字的状况,提出了缓解该市生态压力、提高生态承载力的建议。This article calculated and analyzed the ecological footprint of Qingzhen in 2005, based on ecological footprint model and using the data of 2005, and then compared with the ecological footprint of other different regions. The analysis showed that the ecological pressure and density was tremendously high in Qingzhen. It is found that： （1）The per capita ecological footprint, of Qingzhen was 2. 5440 hm^2 in 2005, and the demand for resources has already exceeded the supply of resources. （2）The per capita ecological deficit was 2. 1240 hm^2 in 2005, The development of ecological environment in Qingzhen is in a sustainable state. OThe ecological footprint of per ten thousand Yuan GDP is 2. 8139 hm^2 , over the average level of western china, and the present resource used model of Qingzhen is highly consumption. At last, aiming at the ecological deficit in Qingzhen city, some suggestions are given to alleviate this city＇s ecological pressure and improve the capacity of ecosystem.
