【摘要】：本文应用生态足迹(ecological footprint,EF)理论和模型,计算和分析了2006-2010年广东省广州市生态足迹和生态承载力情况。对统计年间各年的生态赤字情况进行测算,并结合地方生产总值(GDP)分析了生态足迹与GDP的关系。更就广州市化石能源生态承载力几乎为0的特点,重点分析了能源生态足迹与经济增长之间的联系。最后,就广州市可持续发展问题给出了几点建议。通过对广州市2006年-2010年数据计算的研究结果表明,5年间广州市人均生态承载力基本趋于平稳,总体变化不大；而人均生态足迹在生态容量基本不变的情况下以平均每年2.31%的速度增长,统计年间人均生态足迹处于持续增长的趋势,且各统计年间人均生态足迹均远高于全国人均生态足迹的水平。六类生态生产性土地生态足迹构成中,碳足迹用地占用比例最大；林地比重紧次于碳足迹用地；建筑用地、耕地、草地和渔业用地的占用足迹比例较小。广州市总人均生态足迹与总人均生态承载力之间形成的生态赤字缺口较大,总生态赤字为总生态承载力的11倍,碳足迹用地生态赤字是造成总体生态赤字较高的主要原因。六类生态生产性土地中,仅耕地和渔业用地有生态盈余。万元GDP生态足迹(ecological footprint intensity, EFI)分析结果显示,2006～2010年广州市GDP值快速增长的同时,万元GDP生态足迹呈现逐年下降的趋势,其中能源EFI下降的幅度最为显著。为此,本文对能源足迹与经济增长之间的联系作了深入的剖析。总体看来,从生态足迹分析的结果上看,广州市处于不可持续的发展模式；但广州市通过对能源利用的优化和进口生态承载力,已缓解生态赤字的增长。
[Abstract]:In this paper, the ecological footprint and ecological carrying capacity of Guangzhou City from 2006 to 2010 are calculated and analyzed by using the ecological footprint theory and model. The relationship between ecological footprint and GDP is analyzed, and the relationship between ecological footprint of energy and economic growth is analyzed in the light of the fact that the ecological carrying capacity of fossil energy in Guangzhou is almost zero. This paper gives some suggestions on the sustainable development of Guangzhou. Through the data calculation of Guangzhou from 2006 to 2010, the results show that the per capita ecological carrying capacity of Guangzhou city tends to be stable during the past five years, but the overall change is not significant. However, the per capita ecological footprint is increasing at an average rate of 2.31% per year under the condition that the ecological capacity of the population is basically unchanged, and the per capita ecological footprint is in a trend of sustained growth during the statistical year. The ecological footprint of each year is much higher than that of the whole country. Among the six types of ecological productive land, the proportion of carbon footprint is the largest; the proportion of forest land is less than that of carbon footprint; the proportion of construction land is lower than that of forest land. The footprint ratio of cultivated land, grassland and fishery land is small. The gap of ecological deficit between total ecological footprint per capita and total ecological carrying capacity of Guangzhou city is larger, and the total ecological deficit is 11 times of the total ecological carrying capacity. The ecological deficit of carbon footprint land is the main reason for the higher overall ecological deficit. Only cultivated land and fishery land have ecological surplus among the six types of ecological productive land. The results of the analysis of the ecological footprint of 10,000 Yuan GDP show that the GDP value of Guangzhou City increases rapidly from 2006 to 2010, and at the same time, the ecological footprint of 10,000 Yuan GDP is decreasing year by year, among which the decrease of energy EFI is the most significant. This paper analyzes the relationship between energy footprint and economic growth. As a whole, from the result of ecological footprint analysis, Guangzhou is in an unsustainable development mode, but Guangzhou has alleviated the growth of ecological deficit through the optimization of energy utilization and the ecological carrying capacity of imports.
