黑河流域生态承载力估测

Assessment for Ecological Carrying Capacity of Heihe River Basin

以黑河流域为例，探讨了生态承载力的概念和估测的方法，笔者认为利用自然植被的净第一生产力数据可以反映自然体系的生产能力和受内外干扰后的恢复能力，是自然体系生态完整性维护的指示。

Based on a case study in Heihe River basin,the concept of ecological carrying capacity and the assessment method were approached.It was suggested that the net primary productivity(NPP) of natural vegetation can reflect the productive and recovery capacity and thus is the index of the ecological integrity of natural system.
