Using ecological compensation in wetland conservation is an extremely effective protective measure. Zoigê Plateau wetland have very important strategic meanings in terms of regional and national ecology safety, coping with climate change. The ecological environment of Zoigê Plateau wetland is facing severe challenges such as peatland degradation, desertification, water resource decrease, biodiversity decline, productivity reduce. Drainage, overgrazing and absent of compensation is the main cause for these problems. Ecological compensation in Zoigê Plateau wetland is necessary and feasible. It is suggested to identify the central and provincial government as the main beneficiaries; to optimize the flexibility locally when use the compensation fund; to establish compensation standard by using different levels and types; to ensure the implementation of ecological compensation by using market mechanism and priority policy for local farmers, as well as policy, laws, capacity building, monitoring and assessment, public participation and communication.

Sedge dominated peatlands do not rehabilitate well after being drained for rangelands and specific approaches are required in order to restore these sites. Restoration by blocking drainage canals aims to recover peatland functions, principally by raising the water table. Field surveys in Ruoergai, China identified the status of peatland degradation and satellite image analysis concluded that most of Ruoergai's peatlands are degraded mainly due to drainage and overgrazing. The restoration approach used in Ruoergai resulted in increased water levels up to 26. cm higher than previously recorded in canals. Levels in shallow water canals also increased up to 50. cm, which led to an overflow of water and rewetting of the adjacent peatlands. This resulted in one peat-mining site being filled with water and aquatic vegetation. Pioneering vegetation including Heleocharis Horsetail (Equisetum heleocharis) and Halerpestes (Halerpestes tricuspis) colonized in the restored sites. It was concluded that blocking canals could be an effective method to restore hydrological function of drained peatlands and contribute to vegetation recovery. © 2011 Elsevier B.V.

Shorebirds are globally recognized as long distance migrants. Millions of shorebirds migrate from as far as North East Asia to Australasian and return annually to meet their needs for survival and breeding. The region of Yellow Sea and Bohai Sea in China is one of the most important areas for shorebirds to stopover during the migration period in the East Asian-Australasian Flyway. It is estimated over 80% of the total migratory shorebird populations in the East-Asian Australasian Flyway migrate through this region. A lot of activities of shorebirds survey have being conducted by Wetlands International-China and Wetlands International-Oceania in implementation of the East Asian-Australasian Flyway Shorebird Action Plan since 1996, these has resulted in the identification of the important shorebird sites in the wetlands of Yellow Sea and Bohai Sea. As lack of awareness on wetland conservation, a lot of wetlands around Yellow Sea and Bohai Sea have been greatly reduced due to reclamation, pollution and habitat degradation. Many shorebirds have also been hunted during their stopover in this area. This paper provided the background information of the shorebirds in the wetlands of Yellow Sea and Bohai Sea, the problems and challenges for conservation of the area were analyzed, and priority actions for the conservation of the important area for Shorebirds were given. Enhance public awareness of wetlands conservation through development of a public awareness program, including workshop, training courses as well as education activities should be the first priority for conservation of the Shorebirds in the wetlands of Yellow Sea and Bohai Sea.
