摘　　要：为满足李仙江流域梯级电站防洪、调度、管理的需求,通过交叉检验法比选反距离权重法、自然邻域法、样条函数法、普通克里金法、协同克里金法5种插值方法,发现反距离权重法李仙江全流域进行插值效果最优,各子流域面雨量需根据雨情选定最优插值方法。进一步将面雨量计算和出图过程建立模型,实现自动生成包含李仙江全流域和7个子流域实况面雨量、预报面雨量、降水实况图、降水预报图的word服务材料。研究旨在为李仙江流域提供高时、空分辨率的气象服务资料,进而合理规划利用水资源。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.
