从承载力的起源、演化与发展着手,重点阐述了国内外关于生态承载力的研究进展;论述了目前常用的生态承载力评价方法,包括自然植被净第一性生产力估测法、资源与需求的差量法、综合评价法、状态空间法、生态足迹法等,并对各种评价方法进行了比较评述;指出今后生态承载力研究的发展方向:加强生态承载力基础理论的研究,加强学科交叉融合,应用先进科学技术手段获取数据,实现资源共享。

The origin, evolvement and development of carrying capacity were introduced, then the domestic and overseas progress of ecological carrying capacity were discussed. And the different concepts and the research methods in ecological carrying capacity which include forecast of net primary production, integrated evaluation method,spatlal states method, ecological footprint method,system dynamic method and dispersion of supply and demand method were reviewed based on the contrast of different method and analysis of existed problems . The trend of the research on ecological carrying capacity was pointed out, foundational theory research and cooperation among different subjects should be strengthened, advanced instrument should be applied to obtain data and realize resources sharing.
