• 摘要： 湟水流域由于其獨(dú)特的區(qū)位及環(huán)境特征，使其成為青海東部地區(qū)最重要的生態(tài)安全屏障，本文選取固碳釋氧、水源涵養(yǎng)、土壤保持、生物多樣性四個指標(biāo)來評價湟水流域生態(tài)系統(tǒng)功能。結(jié)果顯示：湟水干流兩岸生態(tài)功能明顯低于其他區(qū)域，成為生態(tài)屏障中非常突出的生態(tài)脆弱區(qū)，尤其是該區(qū)域呈條帶狀東西走向，一定程度上阻斷了南北方向上生態(tài)系統(tǒng)的能流、物流及信息流，影響了生態(tài)屏障整體的生態(tài)服務(wù)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.
