本文借鉴前人的研究成果，归纳分析后得出河床纵向与横向稳定性指标的表达式，并进一步给出河床的综合稳定性指标ＺＷ，将它作为区划河型的判数：ＺＷ＜５，游荡型；５≤ＺＷ≤１５，分汉型；ＺＷ＞１５，弯曲型。为研究游荡河型转化而进行的自然河工模型试验表明，若要将黄河下游的游荡河型转化为限制性弯曲河型，两岸有效的控导工程总长度至少应占河道长度的８８％，每处工程长度需要达到４ｋｍ左右，但就现在的整治工程情况而言，即使来水来沙条件较为有利．短期内转化为弯曲河型也是不可能的。 This paper draws on the research results of predecessors, induces the expression of vertical and horizontal stability of riverbed after inductive analysis, and further gives the comprehensive stability index of riverbed ZW, which is taken as the judgment of zoned river type: ZW <5, Wandering type; 5≤ZW≤15, sub-Han type; ZW> 15, curved type. The natural river model tests conducted to study the wandering river type transformation show that to convert the wandering river from the lower reaches of the Yellow River into a restrictively curved river type, the total length of effective control projects across the Taiwan Strait should account for at least 88% of the length of the river course. Department of the length of the project needs to reach about 4km, but the current remediation projects, even if the conditions of incoming and outgoing water is more favorable. It is also impossible to convert into a curved river in the short term.
