The invention discloses a method for constructing a flood forecasting scheme based on any section. According to the method, a forecasting section is randomly designated and a forecasting scheme is constructed in a flood forecasting process; the river network can be automatically extracted according to the DEM; a confluence area is automatically circled and drawn; according to the method, the rainfall station in the convergence area is automatically extracted, the weight of the rainfall station is automatically calculated according to the Thiessen polygon, the processes of manually modifying coordinates, extracting the water system basin and extracting the basin rainfall station in the prior art are avoided, the efficiency of constructing a forecasting scheme for any section can be obviously improved, and the timeliness problem of forecasting for any section is effectively solved. 本发明公开一种基于任意断面构建洪水预报方案的方法，本方法在洪水预报过程中任意指定预报断面并构建预报方案，能够根据DEM自动提取河网，自动圈画产汇流区域，自动提取产汇流区域内的雨量站，根据泰森多边形自动计算雨量站权重，避免了现有技术中手动修改坐标、提取水系流域、提
