文章采用鱼类种群动态研究中的形态学方法，2008~2012年4季在塔里木河上游段采集1424尾样本，对渔获物叶尔羌高原鳅的种群结构进行分析。结果表明，2008~2012年塔里木河上游段叶尔羌高原鳅平均年龄逐渐升高，多数个体在4+左右，年龄与体长相关性较差，与体重相关性较大。叶尔羌高原鳅的体长和体重随年际增长出现增大趋势，低龄个体资源锐减，野生个体偏瘦，异速生长。结果表明，塔里木河上游段叶尔羌高原鳅平均年龄增长幅度大，年际变化明显，低龄化缺失严重，雌雄差异显著，种群数量资源锐减，不宜捕捞，是亟待保护的土著鱼类。

In order to investigate and research the variability and population dynamics of Triplophysa (Hedinichthys) yarkandensis (Day), and so better to protection the species. take the tradi-tional and classical morphological method, To collected 1 424 samples which come from each quarter of the 2008-2012 four years in the Tarim River upstream section, after analysis the population structure. The results showed that from 2008-2012, between the upstream section of the Triplophysa (Hedini-chthys) yarkandensis (Day) ages increased, younger decreased, the majority of at the 4+, for not suitable fishing. Age with length for poor correlation, with weight-related, the weight increases with age growth. Length and weight growth with annual volatility, the body thin and the growth rate would be more biased uniform growth state of it. Studies have shown that:The growth rate for the algometric,age amplitude, but the younger age is less, weight and length decreases rapidly, male and female difference was significant, population resources plummeted, not fishing. So, Triplophysa (Hedinichthys) yarkandensis (Day) internal variability evident sharply resources are urgent to protect indigenous fishes.
