Wetland is a kind of special ecosystem with multiple functions and rich biodiversity resources. By the end of 1995,117 nature reserves with wetland ecosystem or wetland wildlifes as their major protection targets have been established in China. Those reserves cover a total area of 9 042 800 hm2. In this paper, the status quo of China's wetland resources and the contradiction in protection and exploitation of wetland resources have been described and evaluated, and the positive role of nature reserve construction on the protection of wetland biodiversity has been discussed. Aiming at existing problems, the countermeasures for further enhancing the in situ conservation and for sustainable utilization of wetland biodiversity resources have been put forward.
