The Paleocene-Eocene Thermal Maximum（PETM） was the most prominent warming event in the Cenozoic and serves as a geological analog for the current global warming driven by anthropogenic CO2emissions from burning fossil *** a primary disruptor of Earth's ecosystems, wildfire activity affects the balance of ecosystems, the global carbon cycle, and climate change. Therefore, studying the evolution and driving mechanisms of wildfires during the PETM is essential for predicting wildfire activity under global warming scenarios and for understanding the carbon cycle in the context of wildfire disturbances. Current research on wildfires during the PETM has mainly focused on the Northern Hemisphere, particularly Europe and North America, whereas studies on Chinese mainland remain limited. In this study, we analyzed black carbon（BC）concentration and carbon isotope(δ13C) in the Beigou section of the Nanyang Basin and the Xilutian section of the Fushun Basin to reconstruct the spatiotemporal evolution of wildfires in arid/semi-arid and humid zones. We integrated these findings with those of previous studies on the paleoclimate of the research area to elucidate the driving mechanisms behind wildfire occurrences. Our results indicate that wildfire activity weakened at the onset of the PETM, with the negative carbon isotope period characterized by low wildfire activity, except for a brief resurgence in the Nanyang Basin. During the recovery phase of the PETM, wildfire activity gradually increased, returning to the pre-PETM levels. The prolonged low wildfire state was likely caused by extremely high temperatures and precipitation as well as the resulting vegetation succession. During the PETM recovery phase, increased wildfire activity transformed “short-term carbon sinks” of the biological-atmospheric carbon cycle into “long-term carbon sinks” through the burial of BC. This process of carbon sink conversion may have acted as a negative feedback mechanism, contributing to carbo

关系抽取旨在从文本中提取出实体对之间存在的语义关系,但现有的关系抽取方法均存在关系冗余和重叠的不足,尤其是对于短文本,会因上下文信息不足而出现语义信息不足和噪声大等问题。此外,一般流水线式的关系抽取模型还存在误差传递问题。为此,文中提出一种基于并联残差膨胀卷积网络的短文本实体关系联合抽取方法。该方法利用BERT生成语义特征信息,采用并联残差膨胀卷积网络来捕获语义信息,从而提升上下文信息的捕获能力并缓解噪声。联合抽取框架通过抽取潜在关系来过滤无关关系,然后再抽取实体以预测三元组,从而解决关系冗余和重叠问题,并提高计算效率。实验结果表明,与现有的主流模型相比,所提模型在三个公共数据集NYT、WebNLG和DuIE上的F1值分别为90.9%、91.3%和73.5%,相较于基线模型均有提升,验证了该模型的有效性。
