Design and Implementation of Meteorological Observation Data Check and Feedback System [PDF]
, 2015 近年来地震、洪灾等自然灾害频发，而气象灾害所占比为71%。防灾减灾工作首要环节是做好对气象灾害的预测预警工作。为此气象部门建立了多轨道气象业务体系，开展各类气象服务工作。而各类气象业务的开展与气象信息网络的结合也将愈加紧密，自动化观测效率越来越高，但随之带来的各种误差也造成了气象观测数据的不准确，因此气象观测数据的质量控制就成为气象服务保障工作迫切需要解决的问题。 本课题对贵州省地面自动气象站和区域自动气象站的逐小时观测数据进行质量控制的实现方法进行了详细阐述 ...

How much biotic nativeness matters across human demographic groups
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...
