摘要:生态足迹以定量的方式反映某特定区域人口生产生活的消耗量。衡量经济圈的生态足迹能够反映社会经济发展主力区的可持续发展水平。研究结果表明:三大经济圈的经济发展都过度依赖于资源的消耗,京津冀地区尤为严重;基于生态足迹模型,研究时期内京津冀的生态赤字最高,可持续发展水平最低;长江三角洲和珠江三角洲都处于生态赤字,两个经济圈之间可持续发展水平的差异较小。从时间序列上看,三大经济圈人均生态足迹在1985年至2015年呈增长趋势;其中1985-1995年是快速增长时期,1995-2005年是缓慢增长时期,而2005-2015年的人均生态足迹略有下降。毕业论文关键词:经济圈;生态足迹;可持续发展;时空格局 27481
Spatio-temporal patterns of ecological footprint of three economic regions in China within 1985 to 2005
Abstract:Ecological footprint is a quantitative tool to calculate the consumption of human life and production in a specific area. Yangtze river delta economic circle, the Pearl river delta economic circle and the Jing-Jin-Ji economic circle in China are main economic regions, and they are representatives of restrict relationship between economical development and environment. Results indicate that, the economic development excessively depend on the consumption of resources,especially in Jing-Jin-Ji. Based on ecological footprint models, the ecological footprint per capita of Jing-Jin-Ji circle is the highest, and the sustainable development level of Jing-Jin-Ji is the lowest of the three economic circles during study period. The differences of ecological footprint between Yangtze River Delta and Pearl River Delta are not significance. As for temporal patterns, the ecological footprint per capita of all three economic regions is in the growth trend. Specifically, the ecological footprint was appearing a rapid increasing tendency within 1985 to 1995, while that was a decade of moderate growth from 1995 to 2005. However, the ecological footprint per capita was decreasing gently during the period from 2005 to 2015.
