主 题：Yellow River Sediment allocation Evaluation index Evaluation method Evaluation grade
摘 要：Scientific evaluation of the sediment allocation effects in the Yellow River plays an important role in the comprehensive harnessing of the Yellow River.A new evaluation index system for sediment allocation has been established using the Analytic Hierarchy Process,and six main evaluation indexes have been selected for this *** calculation methods and evaluation criteria of each evaluation index are *** evaluation criterion of bankfull discharge in the upper reach is 2,000 m;/s,that of Tongguan elevation in the middle reach is 325.7 m,and that of bankfull discharge in the lower reach is 4,000 m;/*** evaluation criteria of water volume and sediment volume into the Yellow River are 25 billion m;/a and 300 million t/a,respectively,and that of sediment volume into the sea to maintain stability of the estuary is 130-260 million t/*** comprehensive evaluation method and grade index are proposed,and the effect of sediment allocation in the Yellow River from 1960 to 2015 is *** comprehensive evaluation grades in different periods are *** evaluation results objectively reflect the situation of sediment allocation in the Yellow River,and the new comprehensive evaluation method can be applied to evaluate the sediment allocation scheme of the Yellow River in the future.
