广西动态生态足迹分析

Analysis on Dynamics of Ecological Footprint in Guangxi

以广西2008-2013年的统计数据为基础,采用经典生态足迹模型对广西2008~2013年的生态足迹进行计算,引入资源产量指标,用于衡量广西区的经济发展水平,扩展了生态足迹的应用领域。计算结果表明6年以来,广西人均生态足迹和生态赤字呈快速增长态势,人均生态足迹从2008年的1.655 939 ghm2增加至2013年的2.08 4301 ghm2,人均生态足迹赤字在2013年度达到了-1.258 070 ghm2。这表明人类对自然资源的利用已经超过了生态系统的承载能力,区域生态经济系统处于人类过度开发利用的重压之下,耕地与草地的生态赤字表现尤为明显,化石能源的生态足迹较大。表明广西区经济发展应该加强对耕地的保护,发展新型农业,提高农产品的高附加值。另外,采用新型可再生能源,减少化石能源等不可再生资源的消耗,改变广西区内生态承载力与生态足迹之间的尖锐矛盾,缓解生态系统压力。

The ecological footprint of Guangxi from 2008 to 2013 was calculated by the typical ecological footprint model, based on the statistics of Guangxi from 2008 to 2013 and introducing the resource yield index, which could be used to measure the economic development level and expand the application field of ecological footprint. The results showed that for 6 years, ecological footprint and ecological deficit of Guangxi increased rapidly with average ecological footprint from 1. 655 939 ghmz in 2008 to 2. 084 301 ghm2 in 2013. And average ecological footprint deficit reached - 1. 258 070 ghm2 in 2013. It showed that the utilization of resources was beyond bio-capacities, and region ecological economic system was un- der the heavy press of over-development and over-utilization. The ecological deficit in plough and grass was obvious, and ecological footprint of fossil energy was larger. It showed that the economic development should focus on the protection of plough, and new-style agriculture should be developed to improve the high added-value agricultural products. New-style renewable energy should be used to decrease the con- sumption of un-renewable resources as fossil energy. The incisive contradiction between bio-capacities and ecological footprint should be changed to relieve the press of ecological system.
