摘要： 在简要介绍生态足迹概念的基础上,提出以"国家公顷"(nha)为计量单位计算城市生态足迹的模型·用gha和nha两种方法分别对沈阳市2001年生态足迹进行了计算,说明gha和nha两种方法的异同·计算结果表明:沈阳市2001年生态足迹需求采用gha方法计算的结果为1 2372hm2·cap-1,nha方法计算结果为0 7418hm2·cap-1;生态足迹供给前者为0 7496hm2·cap-1,后者为0 6219hm2·cap-1;前者计算得到沈阳市生态足迹赤字0 4876hm2·cap-1,后者为0 1199hm2·cap-1·并对两种计算方法产生的结论差异进行了详细的分析,进一步说明采用nh...

Abstract: Based on the ecological footprint concept, national hectare or nha is proposed as a new area unit to calculate the urban ecological footprint. For comparison, the ecological footprint within Shenyang was calculated in nha and gha for the year of 2001, with both results compared and analyzed. The results showed that the ecological footprint within Shenyang in 2001 was 1.2372 hm2·cap-1 and the available ecologically productive area was 0.7496 hm2·cap-1, as a results, the ecological deficit was 0.4876 hm2·cap-1 if using gha as unit area. But, the three indices mentioned above were 0.7418 hm2·cap-1, 0.6219 hm2·cap-1 and 0.1199 hm2·cap-1, respectively, if using nha as unit area. The reasons of discrepancies arising from the different area units used are discussed in detail, and it is found that using nha to calculate ecological footprint is well worth studying in application.
