摘　　要：尼雅河是新疆和田地区民丰县境内的主要河流,文章采用3个水文站的实测资料对尼雅河悬移质含沙量和输沙量的年内及年际变化进行分析。结果表明,河流含沙量年内分配与径流同时集中在春季和夏季,含沙量分布与径流相一致,最大年与最小年含沙量极值变化较大;泥沙输移与径流的变化关系密切,输沙量季节变化极大。NIYA river is one of the main rivers in hotan region in Xinjiang,this paper adopts measured data from three hydrological station to analyze the interannual variation of the sediment concentration and sediment discharge of Ni Ya River＇s suspended load.Results showed that the most of its annual distribution of the river sediment concentration and the runoff both happens in spring and summer,which are consistent.Moreover,the extremum change of maximum annual and minimum annual sediment concentration is varied;sediment trans- port and the change of the runoff are closely related, and the seasonal change of sediment discharge is great.
