However, the natural wetlands in China suffered great loss and degradation due to the rapid growth of human population and economy, together with the long-term over-exploitation. Therefore, improving and restoring wetlands＇ various functions, such as slowing the runoff, flood control and drought prevention, water purification and restoring and rebuilding wetlands in the appropriate geographical places are the pressing issues human face today. Based on the fundamental concepts of the wetland restoration, this article expounded its principles and guidelines, illustrated three basic modes, and summarized the main goal and basic strategy in China. Finally the assessment and future trends of the wetland restoration were discussed.展开更多
