摘要:

探究不同海岸条件下深圳红树林的群落特征及碳积累功能, 对深圳宝安西湾红树林、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、土壤有机碳与植株碳含量测定, 对不同群落的生物量与土壤碳密度进行了对比研究。结果表明: 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和233.56t·hm-2; 福田红树林保护区具有最高的土壤有机碳密度(63.10g·kg-1)和土壤碳密度(134.65t·hm-2), 但其土壤含水量与土壤容重均显著低于其余2个样点; 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 community characteristics and carbon accumulation function of mangroves under different coastal conditions in Shenzhen, we measured plant growth indices, soil organic carbon, and plant carbon content in three mangrove wetlands: Bao'an Xiwan Mangrove, Dapeng Luzui Mountain Mangrove, and Futian Mangrove National Nature Reserve. The biomass and soil carbon density of different communities were compared. The results showed that Kandelia obovata, Sonneratia caseolaris, and Sonneratia apetala were the constructive, dominant or associated species in the three mangrove communities of Shenzhen. The vegetation carbon density was highest in the K. obovata (88.03 t·hm-2) and S. caseolaris+S. apetala (233.56 t·hm-2) communities in the Xiwan Mangrove. The Futian Mangrove Reserve exhibited the highest soil organic carbon and soil carbon density (63.10 g·kg-1, 134.65 t·hm-2), though its soil water content and bulk density were significantly lower than the other two sites. The Dapeng Luzui Mangrove community showed the richest species composition and highest soil bulk density, but had relatively smaller plant height, DBH, and biomass. Among all communities, the S. apetala community displayed the greatest tree height, DBH, and vegetation carbon density, yet the lowest soil organic carbon content and soil carbon density. The soil organic carbon content in Futian’s natural K. obovata stand was higher than in other native and exotic mangroves. Among nine mangrove species, K. obovata showed the highest organic carbon content in stems, leaves, and fruits, while Acanthus ilicifolius had the lowest. In terms of carbon content in different plant organs, K. obovata and Bruguiera gymnorrhiza had the highest carbon content in fruits, whereas other mangrove species had higher carbon content in stems and leaves.
