| 摘 要： | 红树林分布于热带和亚热带海岸。漳江口海滩是福建红树林的分布中心,五十年代原有自然分布红树林133.5 ha。近30年来垦伐为耕地30 ha,开辟为水产养殖基地54 ha,人工营造了0.15ha。现有红树林约50 ha,组成的有5科6属6种,其中以木榄及秋茄占优势.红树林保护漳江口海岸不被潮水侵蚀,且能净化河口水体,减轻污染。还可作肥料、燃料、饲料和染料;其树皮含单宁20～30%,可制药、鞣革、染鱼网等。生态和经济效益显著.

| Abstract: | The mangrove flourishes on the seashores of tropics and subtropics.The natural distribution of mangrove on the beach of Zhangjiang River outlet covered an area of ca.133.5 ha.For recent 30 years,among them about 30 ha developed to cultivated land and about 54 ha replaced to the aquicultu- re farms.In 1983 an area of 0.15 ha Bruguiera was planted.Up to the pres- ent time only 50 ha of the original mangrove remained.A survey revealed that they belonged to 5 families,6 genera,and 6 species.Most of them are of Bruguiera gymnorrhiza and Kandelia candel species.Such a forest protects the seashore of Zhangjiang River outlet from soil erosion and mai- ntains the biological communities habituating below the trees.The forests also protect the environment from pollution.Besides,the tree leaves are good sources of fertilizes.Sometimes,the leaves are also used as fuels and feeds.The tree bark contains 20—30% tannin which is employed to manuf- acture medicine,tanning and dyeing fish nets.Both of these produced good ecologycal effects and economic returns. |
