太湖流域超标特大洪水风险预警系统建设及应用

为做好超标洪水调度、保障流域防洪安全,开发建设了由基于水文水动力学耦合的超警超保风险区域预警模型与基于水文学法的洪水淹涝风险快速评估模型共同组成的超标特大洪水风险预警系统,该系统在太湖流域预报调度一体化系统中通过智能交互方式进行模型与系统的紧密集成,实现了预报调度成果的可视化。基于水利一张图的超警超保与淹涝动态展示,实现了预报产品从点到面、从常规预报到影响预测的突破,以及洪水风险由静态评估向实时快速动态分析的转变。应用结果表明：系统在2020年太湖流域性大洪水中累计发布超警超保风险提示39期、洪水淹涝风险评估4期,预测结果与实际基本一致,为科学调度防御超标洪水提供了技术支撑,避免了江苏省苏州市3万多的人员转移,有力保障了太湖流域防洪安全。     

Hypothalamic histamine modulates adaptive behavior of rats at high environmental temperature

Summary Histamine content in the rat hypothalamus was lower at 4°C and higher at 31°C compared to that at 21°C. Pretreatment with -fluoromethylhistidine, a suicide inhibitor of histidine decarboxylase, attenuated both the increased level of hypothalamic histamine and rat adaptive behavior at 31°C. Increase of histamine content in the hypothalamus appears to be an important factor contributing to rat adaptive behavior to high environmental temperature.

The discovery of early Permian reef belt in east Kunlun and its significance

The early permian reef belt is distributed in the southern side of eastern Kunlun, north area of Qinghai-Tibet Plateau. The core-reef facies of thc reel extends from Tuosuo Lake to Huashixia. Lots of reef breccia was found at the southern slope of the mre-reef belt, and to the north of the reef belt there is back-reef limestone. Cacisponges, hydrozoa, bryozoa,Tabulozoa, Tubiphytes and red algae are the main frame-building organisms.Archaeolithoporella, laminated blue-green algaes,Tabulozoa andTubiphytes played a role of binding or encrustating. There are many kinds of epibiont in the mf, including brachiopod, gasterid, foraminifera, echinoderm and simple coral. The type and the characteristics of the reef-building organisms in eastern Kunlun and Animaqing are basically thr same as those in the south of Chi     

Chronology of environmental events over East Asia during the past 130 ka

In the transitional region between the Loess Plateau and deserts, 4 sections located respectively at Yuling, Hengshan, Dingbian and Huining of China are studied. The high-resolution paleoclimatic records obtained show that environmental events on varying time scales have happened over East Asia. These events are dated with the time scales established using the recently-developed approach of Automatic Orbital Tuning. This leads to the establishment of the chronology of the environmental events.
