泉州湾河口湿地桐花树的植被碳密度及分布特征

The Carbon Density and its Distribution of Aegiceras corniculatain Quanzhou Bay Estuarine Wetland

研究了泉州湾河口湿地桐花树的植被生物量、碳含量、碳密度及其分布规律.其结论如下:桐花树的植被生物量与碳密度分别为27.98,12.07t/hm2,且分布规律较为相似,其大小顺序均为树干>树枝>主根>树叶>侧根;桐花树植被的平均碳含量为42.33%±2.22%,其高低顺序为主根(43.88%±0.63%)>树干(43.29%±3.18%)>树枝(42.94%±1.20%)>树叶(42.67%±3.47%)>侧根(38.86%±2.13%).

The biomass,carbon content, carbon density and its distribution rule of Aegiceras cornicu-lata vegetation were investigated in Quanzhou Bay estuarine wetland.The research findings are as fol- lows： Vegetation biomass and carbon density of Aegiceras corniculata were 27.98 t/hm2, 12.07 t/hm2 ,and the distribution is similar,in descending order of their trunk 〉 branch 〉 taproot 〉 leaf lateral root〉 The average carbon content of Aegiceras corniculata vegetation was 42.33% ~ 2.22% ,in descending order of taproot （43.88% ± 0.63%） 〉trunk （43. 29%± 3.18%） ~ branch （42.94%~1.20%）〉 leaf （42.67% ±3.47%）〉lateral root （38.86%±2.13%）.
