近年来,分布式声波传感技术(DAS)以其低成本、高密度、可实时观测等优势在地震学等多个学科领域迅速发展并得到了广泛应用。光纤作为DAS观测系统中重要的传感元件,其本身结构可直接影响数据采集质量,进而影响数据分析结果;同时光纤的物理特性还会影响野外观测成本和观测难度。然而,如何在地球物理观测中选择合适的光纤依然缺乏定量参考。为此,本文根据地震数据的关键特征定义了一套评价指标,用来定量评估DAS观测数据的质量;然后,针对地表浅埋布设DAS设备和垂直井中布设DAS设备两种主要的地震观测系统,设计了对比试验方案,

Environmental racism and air pollution: Pre and post the COVID‐19 economic shutdown
Abstract Decades of research demonstrates that minoritized groups are disproportionately affected by swathes of harmful pollutants, including air pollution, even controlling for low income. Would significantly reducing individual car traffic help reduce the EJ gap?

耕地和草地分别约占地球上无冰土地的12%和26%,是地球上占比最大的两种典型土地利用类型之一,也是我国重要的两种农用地类型。维护耕地和草地土壤质量和健康对我国农牧业绿色可持续性发展、推进生态文明建设具有重要意义。长久以来,施肥是保障和提高耕地和草地生产力的主要农艺措施,但目前关于全面体现施肥对土壤质量和健康变化影响的系统性研究还很有限,对于长期施肥后的土壤质量和健康的整体评价、土壤健康变化的原因与后果等方面的研究仍存在不足。本研究分别基于中国科学院鹰潭红壤生态试验站内(位于亚热带江西省内的丘陵旱作耕地 ...
