摘要
文章应用生态足迹评价模型,通过衡量城市居民在生产和生活中产生的CO2总量和城市森林能够吸收CO2总量之间的平衡关系,对中山市生态环境发展的可持续性进行分析。结果表明,2003~2005年,由于液化石油气的大幅度消费增长,中山市城市森林生态足迹大幅增长。但城市森林承载力稳步增长。2005年中山市城市森林足迹46 058.93 hm2,生态赤字22 091.41 hm2,生态压力指数1.92,处于生态不可持续状态。应尽快通过发展绿色能源、提高能源利用效率、扩大城市森林面积和提高单位面积森林生产力等途径,减少城市森林足迹,提高城市的可持续发展能力。
According to the calculation method of ecological footprint,the ecological sustainability of Zhongshan was analyzed by measuring the balance between discharge volume of CO2 through industrial,domestic consumption and reducing discharge volume of CO2 by urban forest.The result showed that the urban forest footprint was 46 058.93 hm2,the urban forest ecological deficit was 22 091.41 hm2 and the UFI was 1.92 in 2005.The ecological system of Zhongshan is unsustainable.As a conclusion,the paper pointed out the UFF should be decreased and the sustainable development capability should be improved,as soon as possible,by developing green energies,improving energy efficiency,expanding urban forest area and by increasing the productive force of forest.
