| 黄河上游茨哈峡-羊曲干支流河段内鱼类的生态调度需要选择目标鱼类并明确其需求次序。采用2005-2006年、2011年、2012年、2014-2015年、2016年、2017年、2022年茨哈峡-羊曲干支流河段渔获物调查结果，考虑不同鱼类繁殖活动对生态水文过程的需求以及数据可得性，选择反映了鱼类的生活史特征、地理分布特征、保护必要性、种质资源价值和资源量现状等方面信息的10个评价指标构建评价体系，采用聚类分析与非维度排序方法对茨哈峡-羊曲干支流河段分布的21种土著鱼类生态调度需求次序进行分组分析。结果，生态需求等级最高的组别有8种鱼类，主要为适应缓流生境且均为砂砾产卵类型鱼类。根据评价体系综合结果分析，生态需求等级最高的8种鱼类厚唇裸重唇鱼、黄河高原鳅、黄河裸裂尻鱼、拟鲇高原鳅、花斑裸鲤、刺鮈、骨唇黄河鱼、极边扁咽齿鱼为茨哈峡-羊曲河段的主要生态调度目标鱼类，其它13种鱼类作为该河段生态调度的兼顾对象。研究结果可为茨哈峡-羊曲干支流河段生态调度方案的制订提供决策依据。 |

| It is necessary to select the target fish and determine their demand order for the fish ecological dispatching in the reach of Zihaxia and Yangqu tributary in the upper reaches of the Yellow River. Using the results of fish catch surveys in 2005-2006, 2011, 2012, 2014-2015, 2016, 2017 and 2022 in the reach of Zihaxia and Yangqu Tributary, considering the demands of different fish breeding activities on ecohydrological processes and data availability, The evaluation system was constructed by selecting 10 evaluation indexes, which reflected the life history characteristics, geographical distribution characteristics, conservation necessity, germplasm resource value and current resource quantity of fish, etc. Cluster analysis and non-dimensional ranking method were used to analyze the order of ecological scheduling demands of 21 species of indigenous fish distributed in the reach of Zihaxia-Yangqugan tributary. Results There were 8 fish species in the group with the highest ecological demand, which mainly adapted to the slow-flow habitat and were all gritty spawning types. According to the comprehensive analysis of the evaluation system, the eight fish species with the highest ecological demand were Pachychilus pachychilus, Huanghe Triplophysa, Schizopygopsis huanghe, Triplophysa pseudosilurus, Gymnocypris maculatus, Gobio gobionis, Huanghe ossiculus, and Platypharyngodonus maximus, and the other 13 fish species were the main targets of ecological control in the Cihaxia-Yangquhe River section. The results of this study can provide a basis for the decision making of ecological scheduling scheme in the reach of Zihaxia-Yangqu tributary. |
