遥测雨量站网的布设与合理性论证

Design and Rationality Verification of Remote Precipitation Station Network

遥测雨量站网的布设是水情自动测报系统建设中一项重要的工作,应使拟定的遥测站网密度恰当,分布合理。根据遥测雨量站布设原则,分析有资料和无资料流域2种情况下雨量站的布设。并根据实际经验,结合实例,分别以面雨量和以流量精度作为目标函数,对水情自动测报系统遥测雨量站网的布设及合理性进行分析论证。在实际应用中,应根据工程特点,结合流域雨洪特点、现有站网和预报模型综合确定雨量布设站网。

Design and arrangement of remote precipitation station network is an important work in construction of automatic system for hydrological data acquisition ＆ transmission, and it should be of proper network density and reasonable distribution. According to principles for design ＆ arrangement of remote precipitation station, the author makes an analysis on precipitation station design ＆ arrangement of station with information and without information. Taking area precipitation and flow discharge precision as the objective function, remote precipitation station network design ＆ arrangement and its rationality are analyzed and verified combing with practical experiences. In practical use, precipitation station network design and arrangement method should be determined according to project features, valley rain ＆ flood characteristics, existing network as well as forecasting model.
