塔里木河流域生态环境系统演变与治理对策研究

该项目从塔河流域及中下游生态环境状况与资源利用评价，生态环境演变、主要问题及其根源分析入手，结合塔里木河中下游实地踏勘工作，在大量收集有关资料数据和吸收已有研究成果基础上，通过全面、系统的分析、研究和论证，提出了塔河中下游生态环境综合治理思路、途径和方案以及实施对策和政策建议等。该研究首次明确提出了塔河流域生态环境治理的指导方针，即“建设源流，改造上中游，拯救下游”，并提出以塔里木河中下游治理为切入点，全面开展生态环境综合治理，以遏制中下游生态环境恶化的势头，恢复下游“绿色走廊”，并逐步输水到台特玛湖治理思路。首次提出采用工程、生物、管理措施相结合的综合治理新思想和流域生态环境综合治理的“12条”方针。提出了中下游生态环境的基本特征和生态环境系统组成等一系列新观点

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel

JUNO sensitivity on proton decay p → ν K + searches*

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the $p\to \bar{\nu} K^+$ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar{\nu} K^+$ is 36.9% ± 4.9% with a background level of $0.2\pm 0.05({\rm syst})\pm$$0.2({\rm stat})$ events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is $9.6 \times 10^{33}$ years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
