Liaohe Delta wetland as wetlands in China is an important part to climate change and human activities seriously affected. By using the dates of temperature, precipitation, sunshine and so on from1957 to 2006, the climate change on the impact of the ecological environment in Liaohe Delta wetlands was studied with climate statistical analysis methods. Study also cited the past 50 years due to climate change brought Liaohe Delta wetlands and climate disasters, including droughts, floods, typhoons and abnormal weather events. By analyzing climate change on the Liaohe Delta wetland plant communities, biodiversity, wetlands area, the productivity of land, crop pests and diseases, migratory birds, the natural world, further, the impact of sea-level rise, It was obtained the response relationship of climate change on Liaohe Delta wetlands ecological environment.Finally, the research task was proposed in order to adapt to these adverse effects such as climate fluctuations,changes in atmospheric composition,changes in land cover and the evolution of the ecosystem, the study that enhancing the Liaohe Delta wetland habitats to climate change adaptation, resisting pests and diseases spread, Controlling environmental pollution, as well as the adjustment of agricultural structure should be strengthened.
