| 摘 要： | 为探索未来气候变化情景下若尔盖高寒湿地水文过程和水循环演变规律,利用分布式水文模型,研究2020—2050年不同气候变化情景下若尔盖湿地流域径流变化趋势以及气候变化对湿地径流的影响。结果表明:在未来气候变化情景下,若尔盖湿地流域径流呈减少趋势,玛曲站径流减少比率最大,其次为若尔盖站,最后为唐克站;非汛期径流量减少幅度明显高于汛期,若尔盖湿地2020—2050年非汛期径流在未来气候变化情景下径流减少比率大部分在25%以上。非汛期径流的锐减可能会进一步加剧若尔盖湿地的退化和萎缩,导致黄河中下游区域的可利用水资源量减少。

| Abstract: | To explore the hydrological process and water cycle evolution of Zoige Wetland under future climate change scenarios, a distributed hydrological model was used to study the runoff variation trend of Zoige Wetland Basin under different climate change scenarios from 2020 to 2050 and the impact of climate change on wetland runoff. The results show that under the future climate change scenarios, runoff in Zoige Wetland Basin is decreasing, and the runoff reduction ratio at Maqu Station is the largest, followed by Zoige Station and Tangke Station. The reduction of runoff in non-flood season is obviously higher than that in flood season. The reduction ratio of runoff in non-flood season of Zoige Wetland from 2020 to 2050 is more than 25% under future climate change scenarios. The sharp decrease of runoff in non-flood season may further aggravate the degradation and shrinkage of Zoige Wetland, resulting in the reduction of available water resources in the middle and lower reaches of the Yellow River. |
