We argue that three questions are the most important among the contents relevant of ecological restoration, including why, what and how to restore degraded systems. Why to restore determines whether or not the degraded ecological systems should be restored. What to restore is the goal of ecological restoration. The explicit goal of ecological restoration is necessary to guide ecological restoration workers in pursuit of excellence and prevent restoration from being swamped by purely technological activities. And how to restore means the methods and steps we should apply. To ensure the final success of ecological restoration, restored sites should be monitored and managed for long time to determine whether the selected methods are appropriate, and can be remedy better. Only to deal with these effectively, ecological restoration would be the hope for the future.展开更多

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
