化石有机碳风化是地质时间尺度上重要的碳源,对全球碳循环和气候变化具有重要影响,但如何量化一直是个挑战.河水铼(Re)含量的变化被认为具有示踪流域化石有机碳风化强度的潜力,然而Re的来源及其与化石有机碳风化之间的关系还知之甚少.为了更好地认识这一指标的有效性,本文选择重庆市城口县下寒武统水井沱组页岩风化剖面为研究对象,通过元素含量、逐级提取实验等分析,探讨页岩风化序列中Re和硒(Se)的活动性及其与化石有机碳风化的关系.结果表明,化学蚀变指数(CIA)从基岩到风化层逐步升高,指示增强的风化强度.根据逐级提取实验和质量迁移系数(τ)的变化发现,页岩中的Re和Se主要赋存于有机质相,风化过程中与化石有机碳同步流失,而与页岩中的硫化物矿物氧化无明显相关;风化过程中Re和Se不同的地球化学行为导致其与化石有机碳非等量流失.本研究支持Re作为示踪化石有机碳风化的指标,而Se是示踪化石有机碳风化的潜在指标.未来需要不同类型沉积岩剖面与流域相结合的研究,明确河水Re和Se的来源及其与流域化石有机碳风化之间的关系.

城市水系统理论是流域水系统科学在城市尺度的拓展,为解决城市化引起的人水关系失衡和突出水问题(内涝、黑臭和水污染、生态退化等)提供了新的系统化解决方案.现有城市水系统相关研究大多关注水循环单一过程,对水循环及其伴生的物质循环、水生态以及人文等过程互馈机制仍需进一步探索.本文以流域水系统科学和水循环理论为基础,发展了城市水系统的概念、理论和技术体系;以城市多种下垫面条件下时变增益降雨-径流模型为核心,耦合自然-社会水循环及其伴生的水环境、水生态等过程和多尺度海绵措施的影响,研发了城市水系统5.0模型,实现了源头降雨-径流-面源污染负荷、排水管网系统水量水质转输、末端调蓄和净化、社会经济水循环、水系统评估和调控等五大关键模拟功能,成果已在武汉市开展示范应用.结果表明:城市水系统应以城市及其联系的河湖为研究对象,探索城市自然-人工侧支水循环和外江调蓄等耦合,以及社会经济发展、海绵措施对水量-水质-水生态等过程的调控机制.研发的城市水系统5.0模型很好地模拟了城区降雨-径流过程、水体总氮和总磷浓度、社会经济发展特征指标等.与实测数据对比,所有降雨-径流场次的相关系数和纳什效率系数分别处于优秀和良好等级;78.1%的实测点位中总氮和总磷浓度模拟偏差均在良好等级,且相关系数均在0.90以上;在18个社会经济发展特征指标中, 100%、83.3%和69.4%的指标偏差、相关系数和纳什效率系数均在优秀等级.在此基础上,优选源头海绵措施、人工强化措施和源头削减-路径拦截-末端治理等分别明显改善了内涝、水体黑臭和湖泊富营养化.其中10年一遇降雨条件下最大内涝淹没面积削减达32.6%,黑臭水体去除率为65%,水体综合营养指数降低了37%,武汉市2020年绿色发展水平也由现状条件下的0.56提升到了0.67,在城市绿色发展评估体系的五个维度(资源利用、环境质量、生态保护、经济增长和绿色生活)中,生态保护维度改善最明显.本研究将进一步推动城市水文学、环境科学和生态学等多学科领域的交叉和发展,也为我国城市复杂水问题的解决和绿色发展等提供重要的理论和技术基础.

The full array of the Large High Altitude Air Shower Observatory(LHAASO)has been in operation since July *** its kilometer-square array(KM2A),we optimized the selection criteria for very high and ultrahigh energyγ-rays using data collected from August 2021 to August 2022,resulting in an improvement in significance of the detection in the Crab Nebula of approximately 15%,compared with that of previous *** the implementation of these new selection criteria,the angular resolution was also significantly improved by approximately 10%at tens of *** aspects of the full KM2A array performance,such as the pointing error,were also calibrated using the Crab *** resulting energy spectrum of the Crab Nebula in the energy range of 10-1000 TeV are well fitted by a log-parabola model,which is consistent with the previous results from LHAASO and other experiments.
