The Utilization Protection and Afforestation on Mangrove Wetland

The multiple-use potential of mangrove wetland has been presented in the paper.The mangrove stems, which can grow 9～10 m3/(hm2·a)in the stand,can be used as building material,furniture,paper pulp,fiber,charcoal and so on.Many other products can also be obtained from mangroves, such as tannin, medicine, perfume, food and forage.The stands can enhance the output of marine products,cutting down 9～10 times of sea tide velocity and raising 1～2 times of silt deposition velocity.In addition,mangrove areas are suitable place for waterbird rest, ecotourism and recreation.7 nature reserves(6 781 hm2 areas) of mangrove wetland have been established,which have undertaken the protection,research and afforestation of the wetlands so that the recovery and development of mangrove have been promoted in China.
