摘要
采用标准地调查和标准木完全收获法,研究了泉州湾河口湿地秋茄的植被生物量、碳含量、碳密度及其分布规律,从而了解区域内秋茄生态系统的碳储量、碳循环等.研究结论如下:(1)秋茄的植被生物量与碳密度分别为72.58,31.57t/hm^2,且分布规律十分相似,其大小顺序均为低潮位>中潮位>高潮位,树干>树枝>树叶>主根>侧根;(2)秋茄植被的平均碳含量为(42.04±3.27)%,其高低顺序为低潮位>高潮位>中潮位,树干>树枝>树叶>主根>侧根.
The standard land survey and the standard wood complete harvest method were used to study the biomass,carbon content,carbon density and their distribution rule of K.obovata vegetation in Quanzhou Bay estuarine wetland in order to understand the carbon storage,carbon cycle and so on of K.obovata ecosystem in the region.Conclusions are drawn as follows：（1）Vegetation biomass and carbon density of K.obovata were 72.58,31.57 t/hm^2,and the distribution is very similar,in descending order of low tide levelmiddle tide levelhigh tide level,trunkbranchleaftaprootlateral root;（2）The average carbon content of K.obovata vegetation was（42.04±3.27）%,in descending order of low tide levelhigh tide levelmiddle tide level,trunkbranchleaftaprootlateral root.
