摘　　要：运用传统生态足迹方法及其改进方法——能值生态足迹方法,对2005年黑龙江省可持续发展状态进行了分析.结果表明:2005年,采用能值生态足迹方法和传统生态足迹方法计算的黑龙江省生态赤字分别为1.919和0.6256hm2.cap-1.2种方法得到的研究区生态足迹均超过生态承载力,表明该区域经济社会发展处于一种不可持续的发展状态.能值生态足迹方法从能量角度探讨了人类物质需求与生态系统资源供应的关系,并采用能值转换率、能值密度等更加稳定的参数进行计算,一定程度上克服了传统生态足迹方法的缺陷.By using traditional ecological footprint method and its modification, emergy ecological footprint method, the sustainable development status of Heilongjiang Province in 2005 was analyzed. The results showed that the ecological deficits of Heilongjiang Province in 2005 based on emergy and conventional ecological footprint methods were 1. 919 and 0. 6256 hm2·cap^-1, respectively. The ecological footprint value based on the two methods both exceeded its carrying capacity, which indicated that the social and economic development of the study area was not sustainable. Emergy ecological footprint method was used to discuss the relationships between human＇ s material demand and ecosystem resources supply, and more stable parameters such as emergy transformity and emergy density were introduced into emergy ecological footprint method, which overcame some of the shortcomings of conventional ecological method.
