The Liaohe River Estuary Wetland, located in Panjin City, plays a critical role in reducing pollution loads, maintaining biodiversity, and ensuring ecological security in China’s coastal regions, contributing significantly to the implementation of the land–sea coordination strategy. As key components of ecological restoration projects, monitoring and evaluating restoration effectiveness provide a reliable basis for decision-making and ecosystem management. This study established an innovative three-dimensional integrated monitoring and evaluation system combining satellite imagery, UAV aerial photography, and field sampling surveys, addressing the technical gaps in multi-scale and multi-dimensional dynamic ecological monitoring. Through systematic monitoring and the assessment of key indicators, including water environment, soil environment, biodiversity, water conservation capacity, and carbon sequestration capacity, we comprehensively evaluated the enhancement effects of ecological restoration projects on regional ecosystem structure, quality, and service functions. The findings demonstrated that the satellite–airborne–ground integrated monitoring technology significantly improved water quality and soil properties, enhanced soil–water conservation capabilities, and increased biodiversity indices and carbon sequestration potential. These results validate the scientific validity of ecological protection measures and the comprehensive benefits of restoration outcomes. The primary contributions of this research lie in the following: developing a novel monitoring framework that provides critical data support for decision-making, project acceptance, effectiveness evaluation, and adaptive management in ecological restoration; establishing transferable methodologies applicable not only to the Liaohe River Estuary wetlands, but also to similar ecosystems globally, showcasing broad applicability in ecological governance.

Anti-dip rock slopes have a wide development and distribution in the Sanjiang rivers, and their deformation and damage phenomena are particularly prominent among all slope problems in the region. Earthquake is an important dynamic factor to induce landslides, which often leads to large-scale landslide disasters. In this paper, a model test of a reduced scale similar material shaking table was designed and completed using the historical landslide at Zongrong on the left bank of the Jinsha River as an example. By loading different types of seismic waves as well as different frequencies and amplitudes, the deformation damage mechanisms of anti-dip rock slopes and the influence of structural surfaces were investigated. Test results show that there is an elevation amplification effect and skin effect on anti-dip slopes under strong seismic action, the larger the amplitude, the more obvious it is. The rate of increase of the slope acceleration amplification factor is influenced more by frequency than by amplitude. The maximum values of the acceleration amplification 0.2g-0.3g for different amplitude values. The presence of structural surfaces changes the dynamic response characteristics of slope, and there is a clear difference in the amplification effect of their thickness on seismic waves, as thicker sections are suppressed and thinner sections are amplified. Amplitude 0.3g-0.4g is the critical dynamic condition for slope cracking and 0.7g-0.8g is the critical dynamic condition for slope destabilisation damage. The slope damage process can he broadly divided into three stages: the formation of top-of-slope tension cracks and toe-of-slope shear cracks; the expansion of cracks and shallow block shear damage sliding-block toppling; the formation of the main slip surface of the shallow slope and slope damage.
