上海市2000—2009年生态足迹测算与动态分析

文章以上海市统计数据为依据,运用生态足迹模型对全市2000—2009年的生态足迹和生态承载力进行动态分析。结果表明:人均生态足迹逐年递增,平均每年增长6.5%;人均生态承载力呈波动性下降趋势,下降了20.5%;生态赤字呈现逐年加剧趋势;万元GDP生态足迹值相对较低并逐年递减,反映了资源利用效率的提高和经济增长方式的良性转变。上海市对自然资源需求逐年增加,目前已超出了上海市自然生态系统的承载力范围,能源消费主要靠外部供给。

Dynamic measurement and analysis of ecological footprints of Shanghai from year of 2000 to 2009

Based on the statistical data from Shanghai Statistical Yearbook,the ecological footprint(EF) and ecological carrying capacity(ECC) of Shanghai from year of 2000 to 2009 are calculated and analyzed in this paper by using the EF model.The results are as follows: the per capita EF has increased with annual growth of 6.5%;the per capita ECC has declined by 20.5% with a fluctuating trend;Shanghai has always been in ecological deficit with high ecological capacity index,and it takes on worse trends year by year;the EF value per RMB 10 000 of GDP is relatively low and decreasing year by year,which reflects the high use efficiency of resources and the positive change of economic growth.The research indicates that the utilization of natural resource in Shanghai is increasing year by year,which is beyond the capacity of the natural ecological system in Shanghai.And the present energy consumption mainly depends on external supply.
