摘    要:为了定量地把握贵州岩溶地区人类社会经济活动对自然环境的动态影响,文章采用生态足迹模型定量研究方法,利用1978-2008年的历史数据,分析了贵州岩溶地区生态足迹的动态变化与结构状况。结果显示:在研究时段,贵州省岩溶地区的人均生态足迹呈递增趋势;从1997年起,人均生态足迹超过了全国;多年平均生态消耗主要集中在化石燃料用地生态足迹、耕地生态足迹和草地类生态足迹;1978-2008年,贵州省岩溶地区万元GDP生态足迹逐年下降,但一直高于全国的值,并且多年平均值是全国的2.3倍。并在此基础上,提出了6条相关的调控对策:提高利用现有资源的效率,并建立完善的管理体系;积极采用先进技术,提高自然系统的生产率;加大岩溶地区的治理和生态恢复,保护农业生态系统;控制人口数量,提高人口质量;开发水能等能源,发展低碳经济,节约能源消费,调整能源结构;积极加大与外区域联系和合作,促进贸易发展。

关 键 词:生态足迹  动态变化  可持续发展对策  低碳经济  农业生态系统  能源结构  岩溶地区  贵州

Abstract:In order to quantitatively discover the human social and economic activity effecting the dynamic change of natural environment in Guizhou karst area,the regime and structural conditions of the eco-footprints are analyzed by means of quantitative research methods of eco-footprints model according to history data from 1978 to 2008.The results show that per capita eco-footprints in Guizhou Province is on the increase in the research period and exceed the national average from 1997.And the long-time average annual major consumption focuses in three kinds of footprints: fossil fuel land and farmland as well as grassland.The eco-footprints for each 10,000 Yuan of GDP keep decreasing from 1978 to 2008,but the average for many years is still 2.3 times higher than the national average.In light of the above account,6 related regulative countermeasures are put forward,1) enhance the efficiency of the existing resources and establish perfect management system;2) positively use advanced technology and enhance natural system productivity;3) govern and restore karst ecosystem and protect agro-ecosystem;4) control population quantity and improve the population quality;5) develop hydro energy and low-carbon economy,save energy and adjust energy structure;6) actively enlarge regional contact and cooperation to promote trade with other regions.
Keywords:eco-footprint  dynamic change  sustainable development countermeasure  low carbon economy  agroecosystem  energy structure  karst areas  Guizhou
