河川径流水文干旱分析

Analysis of Regional Droughts on Streamflow by Using Kriging Method

根据河川径流记录，应用Kriging优化内插方法，按照游程理论及截距法分析干旱历时、干旱烈度及其条件概率等特征值，评价区域水文干旱，为干旱预报和水文资源管理提供依据。

The drought duration and conditional probabilities at certain seventy level were analyzed based on runs of theory and truncation level method at precipitation stations. The regional drought characteristics was evaluated by using briging method, which provided apractice method for drought prediction and water resources management.
