广东省2010年生态足迹和生态承载力研究

利用生态足迹分析方法，对广东省2010年生态足迹和生态承载力进行了研究，分析探讨广东省经济活动对当地自然生态系统造成的压力及其影响程度，为识别和衡量广东省的可持续发展状态、制定城市建设策略和实现可持续发展提供参考依据。结果表明，广东省2010年人均生态足迹为2.5188 hm²，主要由耕地足迹和能源足迹构成，人均生态赤字为2.078 hm²，远高于全国、全球平均水平。总人口生态足迹赤字为2.17×10⁸ hm²，生态超载力达到4.7倍。与2001年相比，10年来人均生态足迹的总需求上涨了84%，其中林地和耕地涨幅剧增。而生态总供给则下降20%。生态系统的压力和强度与日俱增。建立集约型、节约型及生态型生产及消费模式，促进经济发展与人口、资源、环境相协调是广东省保持可持续发展劲头的主要途径和当务之急。

Study on Ecological Footprint and Ecological Capacity in Guangdong Province

Using analysis method of ecological footprint, the ecological footprint and ecological capacity of 2010 in Guangdong Province was analyzed, and the stress and its influence degree on natural ecological system caused by economic activities were also discussed, in order to provide reference for identify and measure the state of sustainable development, city development strategy and realize the sustainable development in Guangdong Province. The results showed that the ecological footprint was 2.5188 hm² per capita, which mainly consisted of farmland footprint and energy footprint, the ecological deficit was 2.078 hm² per capita, far higher than the average of the national and the world. Total ecological footprint deficit was 2.17×10⁸ hm², ecological overload reached 4.7 times. Compared with 2001, the total demand of per capita ecological footprint rose 84% in nearly ten years, the forest land and farmland were rising rapidly. While ecological supply fell by 20%. The pressure on ecosystem was increasing. It is the main way and the top priority to establish intensive, economical and ecological production and consumption patterns and to promote economic development and Population, resources and environment in harmony in order to keep sustainable economic development in Guangdong province.
