摘要
简要地介绍了承载力及生态承载力的概念及由来,以及利用承载力衡量可持续发展的理论与方法。分别论述了生态承载力的自然植被净第一性生产力估测方法、资源与需求的差量方法、生态承载力综合评价方法及状态空间法的度量方法。依据草原生态系统特性构建了草原区域生态承载力指标体系,探讨了生态承载力在草原区域可持续发展评价中的应用前景。
The concept and origin of carrying capacity (CC) and ecological carrying capacity (ECC), as well as theories and methods of applying carrying capacity to measure sustainable development, are briefly presented and reviewed in this paper. ECC quantitative measurement, including natural vegetation net primary productivity measurement, dispersion of resources and demands measurement, ECC integrated assessment, and the state space approach measurement method, are discussed. Based on grassland ecosystem characteristics, an ECC index system for grassland regions was constructed. The application of ECC in the future in assessing sustainable development for grassland regions was discussed.
