Based on retrieved results of literature and patents related to international wetland ecological restoration, the current status and development of ecological restoration techniques for degraded wetlands in both China and international states were analyzed synthetically. The results showed that the United States was the pioneering country in studies on the wetland ecological restoration, while China began to pay widespread attention from 2000. Compared to the international developed countries, the start time of concern for wetland ecological restoration in China was about 10 years later. The phytoremediation and engineering restoration were the most popular among all the wetland ecological restoration techniques. Besides the United States, the number of publications increased most quickly in China since 2004. The Louisiana State University published most of the researching findings among the international institutions related to wetland ecological restoration. The Chinese Academy of Sciences was the most important institution for wetland restoration study in China. The analysis of the wetland ecological restoration practice in China and international states indicated that the study and application of combined bioremediation techniques would receive more attention for wetland ecological restoration in the future.
