汉江流域骤旱演变规律及其对南水北调中线工程的响应分析OA
Evolution Pattern of Flash Drought in Hanjiang River Basin and Its Response to Middle Route of South-to-North Water Transfer Project
通过识别汉江流域骤旱事件,分析了汉江流域在南水北调中线工程实施前后其骤旱事件特征的差异,并且使用偏最小二乘回归(Partial Least Squares Regression,PLSR)、支持向量机(Support Vector Machine,SVM)和随机森林(Random Forest,RF)3种机器学习方法建立了骤旱历时回归模型,定量分析了南水北调中线工程对骤旱历时的影响.结果表明:①南水北调中线工程实施后,汉江流域骤旱频次从平均每年0…查看全部>>
By identifying flash drought events in the Hanjiang River Basin,the differences in the characteristics of flash drought events before and after the implementation of the Middle Route of the South-to-North Water Transfer Project were analyzed.Moreover,three machine learning methods,partial least squares regression(PLSR),support vector machine(SVM),and random forest(RF),were employed to establish regression models for the duration of flash droughts,and the imp…查看全部>>
