Antibiotic resistance genes (ARGs) are considered to be emerging pollutants related human activities. The rapid development of global urbanization has expanded activities, thereby exacerbating the health risks caused by antibiotic genes. effects urban and rural environments multifarious, which makes source distribution ARGs in environment diversification. Understanding spread is essential for s...
Estuarine tidal flats are located in the land-sea crisscross-sensitive zone. The degraded and shrinking state of major flat landscapes weakens their ecological role maintaining safety coastal wetlands world. However, little attention has been paid to landscape evolution risks due being periphery estuarine wetlands. This study was conducted Liaohe estuary GIS spatial analysis a transition matrix...
High pressure mercury, nitrogen adsorption, nano-CT, and scanning electron microscope with energy spectrum analysis were conducted on core shale samples for studying the characteristics of Taiyuan formation in the eastern uplift of Liaohe depression. The research results show that the shale gas reservoir pores are mainly open pores such as the wedge-shape pores and parallel-plate pores. By a ge...
The precipitation conce ntration degree (PCD) and concentration period (PCP) in the Liaohe River basin (LRB) from 1960 to 2020 were calculated depending on daily data derived meteorological stations. mutations of PCD PCP identified by sliding t-test, spatiotemporal evolution characteristics before after mutation point further analyzed. Cross wavelet transform (CWT) was used reveal influence fou...
