干旱区绿洲散耗型水文模型及其在塔里木河流域的应用

该项目主要内容包括干旱区绿洲水文过程特点的分析：分析了干旱区水文气象特点、土地利用特点以及水量引用、输送（散流）、转化、消耗等水文过程；绿洲散耗性水文模型的建立：在散耗型流域概念基础上，构建了绿洲散耗性水文模型的理论体系和实现框架，提出并建立了干旱区绿洲散耗性水文模型；模型的应用与分析：利用所建立的散耗型水文模型，对喀什、阿克苏、巴州、克州与和田等绿洲的水文循环过程进行了模拟，分析了现状条件下绿洲内水分运动、转化、消耗、利用的规律，结合绿洲水土资源管理规划、重大建设工程的立项与地下水开发利用等问题进行情景分析的模型模拟。 成果类别： 应用技

Determination of the number of ψ(3686) events taken at BESIII

The number of ψ(3686) events collected by the BESIII detector during the 2021 run period is determined to be (2259.3±11.1)×106 by counting inclusive ψ(3686) hadronic events. The uncertainty is systematic and the statistical uncertainty is negligible. Meanwhile, the numbers of ψ(3686) events collected during the 2009 and 2012 run periods are updated to be (107.7±0.6)×106 and (345.4±2.6)×106, respectively. Both numbers are consistent with the previous measurements within one standard deviation. The total number of ψ(3686) events in the three data samples is (2712.4±14.3)×10^
