This discussion is reply to the comments made by Dr. Hyun Il Choi (in press) on the LME proposed by Liu, 2020 concerning the performance criterion for hydrological model. In this reply I answer the comments and I try to clarify that there are two aspects of the LME. I believe that Dr. HyunIl Choi had just understood one aspects of the LME in his comments, which had confused him. Actually, both the value of the estimated LME and its corresponding confidential level are important to understanding the merits of LME for assessing the performance of hydrological model.

回复 HyunIl Choi 的“评论 Liu (2020)：一个水文模型的合理性能标准”

本次讨论是对Hyun Il Choi 博士（正在印刷中）对Liu, 2020 提出的关于水文模型性能标准的LME 的评论的回复。在此回复中，我回答了评论，并试图澄清 LME 有两个方面。我相信，HyunIl Choi 博士在他的评论中刚刚理解了 LME 的一个方面，这让他感到困惑。实际上，估计的 LME 值及其相应的机密级别对于理解 LME 评估水文模型性能的优点很重要。
