Method for identifying pollutant transmission path

The invention provides a pollutant transmission path identification method. The pollutant transmission path identification method comprises the following steps: (A1) obtaining observation pollution data corresponding to each point location in a region; (A2) predicting predicted pollution data of each point location in future time; (A3) gridding the area, and obtaining pollution data of each grid by using observed pollution data and predicted pollution data; (A4) calculating the wind direction angle Di of any grid, wherein i = 1, 2... N, and N = 8; and (A5) obtaining a wind direction Dave in any grid, and further identifying a pollutant transmission path. The method has the advantages of accurate identification and the like. 本发明提供了污染物传输路径的识别方法，包括以下步骤：(A1)获得与区域内各点位对应的观测污染数据；(A2)预测各点位在未来时间内的预测污染数据；(A3)将区域网格化，利用观测污染数据和预测污染数据获得每个网格的污染数据；(A4)计算任一网格的风向角度Di，i＝1,2...N，N＝8；(A5)获得任一网格内的风向Dave，进而识别出污染物传输路径。本发明具有识别准确等优点。
