Fast radio bursts(FRBs) are highly dispersed millisecond-duration radio bursts,[1,2.of which the physical origin is still not fully understood. FRB 2.2.112.A is one of the most actively repeating FRBs. In this paper, we present the collection of 1863 burst dynamic spectra of FRB 2.2.112.A measured with the Five-hundred-meter Aperture Spherical radio Telescope(FAST). The current collection, taken from the observation during the FRB active phase from April to June 2.2., is the largest burst sample detected for any FRB so far. The standard PSRFITs format is adopted, including dynamic spectra of the burst, and the time information of the dynamic spectra, in addition, mask files help readers to identify the pulse positions are also provided. The dataset is available in Science Data Bank, with the link https://***/10.57760/sciencedb.j00113.00076.

目的研究丽江野鼠鼠疫自然疫源地分布范围、特征,主要宿主、媒介,探讨其规律,为鼠疫防治提供科学依据。方法运用流行病学方法对以5次发现疫情的鹿子村为中心的6个乡镇17个村委会71个村民小组展开调查,采集指示动物血清、啮齿类动物和媒介蚤标本,分离鼠疫杆菌和检测鼠疫F1抗体综合判定。结果判定目前丽江野鼠鼠疫自然疫源地范围约450 km。,为5个乡镇14个村委会49个村民小组。基本掌握了丽江以黄山南溪村委会鹿子村为中心的野鼠鼠疫自然疫源地的范围、边界和安全边际。结论丽江野鼠鼠疫自然疫源地的位置比较特殊,范围广泛,生态环境较为复杂。动物疫情处于异常活跃状态,开展鼠疫监测、灭鼠灭蚤以及加强疫情"三报",采取科学合理的防控措施,完全可以防止人间鼠疫的发生。

地层孢粉数据是古植被和古气候重建等古环境研究的重要基础。孢粉数据库推动古环境研究从点到区域和全球尺度,从定性到定量,从而实现在大空间尺度和长时间序列上探索植被、气候和人类干扰的相互关系,以更好地理解地球系统的演变。该数据集整合了全国第四纪末期(5万年以来)共372.地层花粉序列,涵盖790个花粉类群,样点分布于中国30个省级行政区与领海。数据集包含地层花粉采样点的地名、经纬度坐标和海拔高度、数据来源、样品类型、沉积物长度、样品数量、测年方法及测年数量、时间跨度和参考文献,以及每个采样点的花粉含量百分比。数据主要来源于2.世纪80年代至今。采样点集中分布在温带和亚热带森林、温带草原和荒漠以及青藏高原高寒植被区域;在深海到青藏高原不同海拔高度都有分布,但集中在海拔2.00 m之下。按照数据来源区分,原始数据样点178个,占47.8%;数值化数据194个,占52.2.。按照样品类型分类,多数样点为湖泊样品(151个)、冲积物/洪积物样品(99个)与泥炭样品(67个),占总样点数的85.2.。年代测定的主要方法为放射性碳同位素手段(占样品总数的93.8%),大部分记录有2.10个测年数据。采样点的平均花粉类群数量是19个,以4-30个花粉类群的采样点最多。代表性花粉类群(松属(Pinus)、栎属(Quercus)、蒿属(Artemisia)、禾本科)含量的时空分布格局表明,从末次盛冰期到全新世,这些花粉科属的分布范围扩大,含量也增加,但分布区域具有分异。半个多世纪以来,孢粉学工作者建立中国大部分地区的地层花粉记录,为探究古环境演变及其气候变化、人类活动驱动机制奠定了重要的基础。
