西江、北江下游及三角洲网河河道同步水文测验成果分析

1999年汛期，西江、北江下游及三角洲开展了历史上规模最大、项目最齐全的同步水文测验工作。对该次测验进行了简要的介绍，并通过对测验成果的合理性分析，论述了该成果的测验精度、上下边界条件和洪潮代表性，进而指出了珠江三角洲河网主要节点和八大口门水量分配比发生了变化及所带来的影响。

Analysis on Results of Simultaneous Hydrometry in the Downstream of Xijiang River and Beijiang River and the Net Rivers of Pearl River Delta

During the flood period of 1999 a simultaneous hydrometry, on the largest-scale and the fullest-items in history, was carried out in the downstream of Xijiang River, Beijiang River and the net rivers of Pearl River delta. This paper presented briefly the simultaneous hydrometry. After analyzing rationality of the results, the paper expounded the precision of the hydrometry, the boundary conditions of upstream and downstream and therepresentation of flood-tide. Furthermore, the paper put forward the change of water distribution proportion of main river nodes in Pearl River delta and Eight Estuaries, including its influence in hydrologic cycle.
