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...
