Estuarine wetland degradation of Liao River caused by human activities has gradually caught people’s attention. It has left great influence on structure, quality and functions of natural ecological system. This thesis took Panjin area as the research object and applied remote sensing and GIS technology to analyze structure, quality, functions and impact factors of the ecological system in Panjin area. The results show climate warming is an important reason for the influence that causes changes in wetland ecological system of Panjin area. To a certain degree, development of economy, agriculture, and industry has also impacted the changes in structure, quality, and functions of ecological system in Panjin area.
