摘要
生态足迹是一种评估区域可持续发展程度和人类对自然干预程度的度量指标。通过对一般生态足迹法的调整,运用本地生态足迹模型,对宁波市2002年和2005年本地生态足迹进行了计算。结果表明,宁波市人均本地生态足迹分别为3.1553和4.3440hm2,人均生态承载力分别为0.3514和0.3649hm2,人均本地生态赤字分别为2.8253和3.9992hm2;2005年宁波市生态足迹强度指数达到了12.599,这意味着宁波市在向每1hm2土地索取本应是12.599hm2土地才能提供的生态服务,反映出宁波市的生产和消费需求超过了生态环境系统的承载能力,生态环境呈现逐步恶化的趋势,可持续发展状况不容乐观。
Ecological Footprint is a significant account for overall assessment of the status of sustainable de- velopment and a comprehensive indicator for human recourse consumption. Calculation of the local ecological footprint of Ningbo City in 2002 and 2005 shows that the average local ecological footprint is 3. 155 3 hm2 and 4. 344 0 hm2 , ecological capacity is only 0. 351 4 hm2 and 0. 364 9 hm2 , and the local ecological deficit is 2. 825 3 hm2 and 3. 999 2 hm2. Ecological footprint intensity index of Ningbo in 2005 is 12. 599. From the re- sults it follows that the demands of human consumption exceed the capacity of natural ecosystem and ecologi- cal environment is deteriorating at a rapid pace. In a word, the situation of sustainable development in Ning- bo City is not optimistic.
