红树林湿地的利用及其保护和造林

The Utilization Protection and Afforestation on Mangrove Wetland

本文综述红树林湿地的各种重要价值，它的林分木材生产力可达９～１０ｍ３／（ｈｍ２·ａ），用于建筑、家具，制造纸浆、纤维、木炭等多方面。红树林可生产：丹宁、药品、香料、食品、饲料；促进海产品生产；供水禽栖息；降低潮水速度９～１０倍；提高淤积速度１～２倍；提供旅游娱乐场所。中国已建立红树林湿地保护区７处，面积共６７８１ｈｍ２，保护区承担湿地保护、科研和造林任务，促进了红树林的恢复和发展。

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