摘要:
以广西电网直调水电厂所处的西江流域为研究对象,基于GIS技术,在对西江流域面雨量监测区域基础信息处理基础上,采用比较分析方法,开展分流域面雨量计算方法研究,结果表明:(1)以1:5万数字高程模型为数据基础,针对西江流域河网、自动气象站、水电站等分布特点,结合水系、等高线特征,沿水系分水岭对西江流域干流进行精细化分区,为分流域面雨量计算提供基础参数;(2)对分流域面雨量采用算术平均法与泰森多边形法计算,结果为两种方法计算结果偏差较小,取算术平均法为流域分区面雨量计算方法;(3)逐小时处理、计算面雨量实时数据,实现西江流域面雨量的实时监测与预警服务。
Abstract:
Taking Xijiang river basin where the Guangxi hydraulic power plant locates as the research object, based on basic processing the information of the areal precipitation monitoring in Xijiang river basin and GIS technique, calculation method of basin area rainfall was carried out by using comparative analysis method, the results show that:(1) Based on the data of 1:50000 digital elevation model, according to the characteristics of distribution of Xijiang river basin, automatic weather station and hydropower station, the refine area partition of Xijiang river trunk stream is made along the river watershed to provide basis parameters of basin areal rainfall calculation; (2) The obtaining Basin areal rainfall by using the arithmetic mean method and the Thiessen polygon method show the smaller deviation; (3) calculation of areal rainfall by hours realize real-time monitoring and early warning of Xijiang river basin areal precipitation.
