摘要： 探究不同海岸条件下深圳红树林的区域性群落特征及碳积累功能，对深圳市西湾红树林、大鹏鹿咀山庄红树林、福田红树林国家级自然保护区3个红树林湿地的主要红树群落进行植物生长指标、植株碳含量、土壤理化性质与有机碳测定，对比研究不同群落的生物量与碳密度。/t/n秋茄、海桑、无瓣海桑是深圳3个样点红树林群落的建群种、优势种或伴生种，3个样点以西湾红树林的秋茄和海桑+无瓣海桑群落的植被碳密度最高，分别为88.03 t·hm-2、233.56 t·hm-2，福田红树林保护区具有最高的土壤有机碳、土壤碳密度（63.10 g·kg-1、134.65 t·hm-2），但其土壤含水量与土壤容重均显著低于其余2个地区，大鹏鹿咀山庄红树林群落物种组成最丰富，土壤容重最大，而群落株高、胸径及生物量均较小；不同红树群落均以无瓣海桑群落的树高、胸径与植被碳密度最高，但其土壤有机碳含量、土壤碳密度均最小，福田自然秋茄林的土壤有机碳含量高于其余乡土与外来红树林；9种红树植物茎、叶、果的有机碳含量均以秋茄最高，以老鼠簕最低，不同器官碳含量中，秋茄、木榄均以果实含量最高，其余红树植物以茎、叶的有机碳较大。

Abstract: To explore the regional community characteristics and carbon accumulation function of mangroves in Shenzhen under different coastal conditions, the plant growth indexes, plant carbon content, soil physical and chemical properties and organic carbon of the main mangrove communities in three mangrove wetlands of Xiwan Mangrove, Dapeng Luzui Mountain Mangrove and Futian Mangrove National Nature Reserve in Shenzhen were measured, and the biomass and carbon density of different communities were compared. The results showed that Kandelia obovata, Sonneratia caseolaris, Sonneratia apetala were the constructive species, dominant species or associated species of mangrove communities in Shenzhen. The vegetation carbon density of K. obovata and S. caseolaris+S. apetala community in Xiwan mangrove was the highest, which was 88.03 t·hm-2 and 233.56 t·hm-2, respectively. The soil organic carbon and soil carbon density of Futian mangrove reserve were the highest (63.10 g·kg-1, 134.65 t·hm-2), but its soil water content and soil bulk density were significantly lower than those of the other two regions. The species composition and soil bulk density of mangrove community in Dapeng Luzui Mangrove were the most abundant, while the plant height, DBH and biomass of the community were smaller. The tree height, DBH and vegetation carbon density of S. apetala community were the highest among different mangrove communities, but its soil organic carbon content and soil carbon density were the lowest. The soil organic carbon content of Futian K. obovata wildwood was higher than that of other native and exotic mangroves. The organic carbon content of stems, leaves and fruits of 9 mangrove plants was the highest in K. obovata, and the lowest in Acanthus ilicifolius. Among the carbon contents of different organs, the fruit content of K. obovata and Bruguiera gymnorrhiza was the highest, and the organic carbon of stems and leaves of other mangrove plants was larger.
