• 摘要： 湟水流域由于其独特的区位及环境特征，使其成为青海东部地区最重要的生态安全屏障，本文选取固碳释氧、水源涵养、土壤保持、生物多样性四个指标来评价湟水流域生态系统功能。结果显示：湟水干流两岸生态功能明显低于其他区域，成为生态屏障中非常突出的生态脆弱区，尤其是该区域呈条带状东西走向，一定程度上阻断了南北方向上生态系统的能流、物流及信息流，影响了生态屏障整体的生态服务功能。
• Because of its unique location and environmental characteristics, Huangshui river basin has become the most important ecological safety defence in the east of Qinghai province, in this paper, carbon fixation and oxygen release, water conservation, soil conservation and biodiversity were selected to evaluate the ecosystem function of Huangshui river basin.The evaluation results show the ecological function of the riversides of the main stream of the Huangshui river is obviously lower than that of other regions, it has become a very salient ecological fragile zones in the ecological defence, especially the area is banded from east to west, to some extent, it blocks the energy flow, material flow and information flow of the ecosystem from north to south, and affects the overall ecological service function of the ecological defence.
