Abstract: The paper deals with the biomass and production of principal secondary shrub in mangroves of Qingland harbour in Hainan Island.The community biomass of Limintzera racemosa,Ceriops tagal and Avicennia marina were measured by harvest method.The result shows that the biomass of these communities is 14.296,11.613 and 9.604t/ha,and their mean net production is 2.043,1.659 and 1.067 t/(ha.a),respectively.The biological productivity of the communities is respectively low,therefore,they should be transformed.In addition,the paper analyses the relation between biomass and leaf area index,and a transformation suggestion for each community is put forward.
