Soil microbial residue carbon (MRC) represents a significant component of soil carbon pools and regulates the response of soil carbon sequestration to precipitation changes. However, the response of soil MRC to extreme drought and wetness and the underlying mechanisms in regional grassland ecosystems remain unclear. Here, we quantified the responses of soil MRC content to extreme drought and wetness and identified the key driv...

The thermal discharge of Daya Bay Nuclear Power Plant has a certain impact on the ecological environment of the adjacent waters. In order to understand and evaluate changes in the fish egg community structure in the adjacent waters of Daya Bay Nuclear Power Plant and their relationship with environmental factors, four surveys were conducted to investigate fish eggs in January (winter), March (spring), August (summer) and Novem...

The spatial and temporal distribution of agricultural water requirement can provide a scientific basis for regional drought and disaster mitigation management and optimal allocation of irrigation water resources. The irrigation water requirement and irrigation water requirement index of the Hebei Plain during 57 years were calculated by a long series of data of 22 weather stations from 1961 to 2017, and the spatial and tempora...
