无资料地区省界断面流量推算方法研究

摘要

由于部分新建省界断面水资源监测站点的建设难度大、周期长，在这些地区无法通过建站观测方式获取水文资料。为获取现状条件下的省界断面的水量信息，分别采用直接水文比拟法、间接水文比拟法以及综合推求法，对卢溪水马头山断面、梅江河三桥断面、金沙江夺通川渠断面、生达青川藏断面、涪江米心断面和汉江冷水镇断面流量进行了推算。结果表明，3种方案的推求流量成果均符合规范要求，对于一些偏远地区省界水量监测断面的水量推求具有一定的借鉴意义。%To obtain the flow data of some provincial cross - sections in un - gauged area,three methods,including the direct hydrologic analogy,the indirect hydrologic analogy and the combined calibration method are proposed. The flow at Matoushan section of Luxi River,Sanqiao section of Meijiang River,Duotong Section of Jinsha River on the border of Sichuan Province and Yunnan Province,Shengda Section on the border of Qinghai Province,Sichuan Province and Tibet,Mixin section of Fujiang Riv-er,Lengshuizhen Section of Hanjiang River are calculated. The results show that the calculated flow by the above methods meet the requirement of the standard. They have a certain reference for the flow calculation of provincial cross - sections in remote re-gions.
