摘要
采用横断面图比较法和河底高程过程线法对阿勒泰水文站测流断面河床变化情况进行分析,得出阿勒泰水文站河道断面年际变化较小,河床较为稳定,断面稳定性高。经测站水位流量单值化分析。结果表明,流量关系点对综合关系线的相对误差及时段总量误差均符合《水文巡测规范》(SL 195-2015)对二类精度测站的相关要求,采用原水位流量关系线推求阿勒泰水文站水量与单值化所推求年平均水量比值符合水量平衡分析结果。
The cross-sectional comparison method and the river bottom elevation process line method are used to analyze the riverbed change of the gaging section of Altay Hydrological Station. It is concluded that the inter-annual variation of the channel section of the Station is small, the riverbed is stable, and the section stability is high. The single-value analysis of the water level flow through the station. The results show that the relative error of the flow relationship point to the comprehensive relationship line and the total time period error are in line with the relevant requirements of the Hydrological Surveying Specification(SL 195-2015) for the second-class precision station, and the original water level flow relationship line is used to estimate Altay. The ratio of the water volume and the single-valued annual average water volume in the hydrological station is in line with the water balance analysis results.
