李仙江流域面雨量最优计算方法及业务自动化研究
Research on the Optimal Calculation Method and Business Automation of Surface Rainfall in the Lixianjiang River Basin
摘要
Abstract
In order to meet the needs of flood control,scheduling,and management of cascade hydropower stations in the Lixian River Basin,this paper uses cross validation method to select five interpolation methods:inverse distance weight method,natural neighborhood method,spline function method,ordinary kriging method,and collaborative kriging method.It is found that the inverse distance weight method has the best interpolation effect for the entire Lixian River Basin,and the optimal interpolation method for surface rainfall in each sub basin needs to be selected according to the rainfall situation.It further establishes a model for calculating and mapping surface rainfall,achieving automatic generation of Word service materials containing actual surface rainfall,forecast surface rainfall,precipitation actual maps,and precipitation forecast maps for the entire Lixian River basin and 7 sub basins.The research aims to provide high and spatial resolution meteorological service data for the Lixian River Basin,in order to plan and utilize water resources rationally.关键词
