###### Abstract  
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.

and enhancing human well-being, while addressing the interconnectedness of social and ecological systems [2]. In China, the General Office of the Ministry of Natural Resources, the General Office of the Ministry of Finance, and the General Office of the Ministry of Ecology and Environment jointly issued the \"Guidelines for Ecological Protection and Restoration Engineering of Mountains, Rivers, Forests, Fields, Lakes, and grasses (Trial)\". This document represents the first standardized framework with general principles to systematically guide ecological protection and restoration practices, grounded in the concept of mountains, rivers, forests, fields, lakes, and grasses as an integrated life community. As one of the largest wetland reserves in China, the Liaohe Estuary Wetland not only plays an important role in ecological protection, but also provides a vital habitat for bird migration and plays a positive role in protecting regional biodiversity. Beyond its ecological functions, the need industry and wetland tourism in the Liaohe Estuary have generated substantial economic benefits for local communities, becoming a key pillar of regional sustainable development [3; 4]. However, human activities such as urban construction, agricultural development, fishery resource utilization, and industrialization, as well as natural factors such as climate change, have a significant impact on the water sources and area of wetlands, resulting in the gradual fragmentation of wetland landscapes [5; 6]. With rapid socio-economic growth and population increase, wetland degradation has become increasingly severe, posing a major challenge to ecological sustainability [7; 8]. Human activities not only have a profound impact on the provision of wetland ecosystem services, but also heavily rely on the diverse ecosystem services provided by wetlands to maintain socio-economic development [9; 10; 11].
