贵州省近年来生态足迹动态分析

Analysis of Ecological Footprint of Guizhou Province in Recent Years

为定量评价贵州省生态可持续发展状态,以贵州省2007—2011年统计年鉴数据为依据,基于生态足迹方法,对贵州省的生态足迹和生态承载力进行计算分析。结果表明:研究期内贵州省人均生态足迹不断增长,由2007年的0.962 4hm2增长到2011年的1.044 3hm2;人均生态承载力持续下降,由2007年的0.427 4hm2减少到2011年0.405 2hm2;生态赤字不断加大,其中2010年生态赤字最大,达到0.648km2/人,持续的生态赤字表明贵州生态环境处于不安全状态,难以实现可持续发展。人均生态足迹增加的主要原因是能源消耗足迹的增加,耕地资源的减少,导致人均生态承载力下降。基于此提出了加强土地资源的管理和利用等方面的建议,以减少生态赤字。

To quantitatively evaluate the state of ecological sustainable development in Guizhou,the ecological footprint analysis method was used to calculate and analyze the ecological footprints of Guizhou from 2007to2011 with the data from the statistical yearbooks.The results show that during the study period,the ecological footprint per capita of Guizhou increased to 1.044 3hm2 from 0.962 4hm2 and the ecological capacity per capita reduced from 0.427 4hm2 to 0.405 2hm2,and the ecological footprint per capita exceeded the ecological capacity per capita,ecological deficit arises,the maximum ecological deficit per capita is 0.648 square kilometers per capita in 2010.The continued ecological deficit indicates the ecological environment of Guizhou is in an insecurity status,difficult to achieve sustainable development.The main reason for the increase of the ecological footprint per capita is the increase of the energy consumption footprint,the decrease of the cultivated land resource leads to decline of the ecological capacity per capita.Based on this,were suggestions including strengthening the management and utilization of the land resources and so on put forward in order to reduce the ecological deficit.
