基于生态足迹的毕节试验区生态承载力动态分析

Ecological Footprint Based Experimental Dynamic Analysis of Ecological Carrying Capacity of Bijie Ecological Experimental Area

为了了解毕节试验区的生态环境是否处于可持续发展状态,运用生态足迹、生态承载力的理论和计算方法对毕节试验区1987 ～2007年的生态状况进行评估,计算得出毕节试验区人均生态足迹从1987年的0.3875 hm2增长到2007年的0.7549 hm2还得出了人均生态承载力从1996年到2007年在0.4848 hm2到0.5669hm2之间浮动,并根据生态足迹和生态承载力的结果求出毕节试验区的生态赤字＜0,生态承载力供需平衡指数＞1,从而得出毕节试验区处于不可持续发展状态.并依据相应的计算分析结果给出了相应的对策建议.

In order to understand whether the ecological environment of Bijie test area is in a sustainable development state or not,this paper uses the theoretical and computational methods of ecological footprint and ecological carrying capacity to assess the ecological status of Bijie experimental area of 1987-2007,calculates the ecological footprint per capita which growing from 0.38748 hm2 to 0.7549 hm2 in1987 to 2007,and also calculates the average personal ecological carrying capacity floating between 0.4848 hm2 and 0.5669 hm2 from 1996 to 2007.And according to the results of ecological footprint and ecological capacity,we know that Bijie test area ecological deficit ＜0,and find the ecological carrying capacity supply-demand balance index ＞ 1.Ecological deficit and ecological carrying capacity supply-demand balance index show that Bijie test area is in an unsustainable state.And we also give corresponding countermeasures and suggestions according to the corresponding results and analysis.
