摘要
利用生态足迹分析方法,对天水市2004年生态足迹和生态承载力进行了研究。结果表明,天水市2004年人均生态足迹为0.978 5 hm2,比全国水平低0.52 hm2;人均生态承载力为0.57 hm2,比全国水平低0.03 hm2;人均生态赤字为0.41 hm2,超载率为72%,生态压力较小。在此基础上,提出了缓解天水市生态压力的建议。
Adopting the method of ecological footprint, the ecological footprint and ecological capacity of Tianshui City in 2004 were analyzed. The results showed that the ecological footprint of Tianshui was 0. 978 5 ha/capita in 2004, and 0.52 ha/capita lower than the national average; the ecological capacity was 0.57 ha/capita, 0.03 ha/capita lower than the national average; the ecological deficit was 0.41 ha/caplta, The overload rate was 72% , and the ecological pressure was relatively lower. Based on these, some suggestions were put forward to alleviate Tianshul City' s eco-pressure and improve the capacity of ecosystem.
