摘　　要：汉江干支流上多座水利枢纽工程的修建,使汉江众多水文站由天然水文进入受水利工程影响的环境水文,其水文情势完全受人工调节,水文要素之间关系复杂多变,这给水文测验和成果计算带来了很大的难度。为此,我们研究出了适合受汉江水利工程影响的环境水文测验方法,提出了水库下游测站输沙模数采用当年入库输沙量加区间来沙计算公式。其测验方法可供同类测站参考。Due to construction of water structures on the main stream and tributaries of the Hanjiang River, the natural hydrological condition monitored by hydrological stations has become in environmental hydrologic regime, which means the hydrological condition is now under the control of human interference and the relationship between hydrological elements is various and complicated, so that it is difficult to make hydrometry and calculation. This paper introduced several methods for hydrometry under the condition of water structures on the Hanjiang River and provided a formula for calculating sediment runoff modulus.
