摘 要: 红树林湿地是分布于热带亚热带海岸及河口潮间带地区的以红树植物群落为核心的一种特殊的海洋湿地类型,在食物供应、野生物种种质资源保存及种群存续维持、物种多样性保护、区域海洋环境净化、生态平衡维持、碳汇及气候调节维系等方面发挥着重要作用。红树林湿地是多种渔业资源生物的栖息地、繁育场、索饵场。多年来,由于人口压力和经济发展影响,红树林湿地质量下降、面积萎缩,红树林湿地恢复已成为世界性热点。 广东沿海是红树林的重要分布区,近几十年来,随着人口增加与经济持续发展,人类的干扰活动越来越大,广东沿海红树林湿地生态系统己成为高脆弱性生态系统,也面临着生态系统退化、生物资源枯竭、生物多样性急剧衰退和生态环境恶化等严重问题,已成为广东沿海渔业资源衰退的重要原因之一。系统地开展广东沿海红树林海洋生态效应研究,摸清红树林生态系统的环境和生物效应,探讨其碳汇机理、对大气温室效应的抑制以及对污染物的降解作用,能有效地为已退化的广东沿海红树林生态系统的修复提供参考依据。 本研究选取广东省沿海8个主要红树林分布区域进行研究:惠州大亚湾红树林公园、珠海淇澳岛红树林自然保护区、深圳福田红树林保护区、澄海澄饶围红树林、饶平浮任村红树林、茂名市水东湾红树林、江门市广海湾红树林以及廉江市高桥红树林观光旅游区。分析红树种类11种,包括红海榄(Rhizophora stylosa)、桐花树(Aegicerascorniculatum)、老鼠簕(Acanthus ilicifolius)、木榄(Bruguieragymnorrhiza)、海漆(Excoecaria agallocha)、秋茄(Kandelia candel)、银叶树(Heritiera littoralis)、卤蕨(Acrostichum aureum)、榄李(Lumnitzera littorea)和白骨壤(Avicennia marina)等10种本地种,以及无瓣海桑(Son Mangrove wetland is a special marine wetland type in tropical and subtropicalcoastal and Estuarine Intertidal area. It’s core is the mangrove communities. It playsan important role in the food supply, the conservation of wild species germplasm, themaintain of population, the protection of the species diversity, the purification ofregional marine environment, the maintain of the ecological balance, carbonsequestration and the regulation of climate. Mangrove wetland is the habitat, breedingfarm and feeding grounds for a biological variety of fishery resources. Over the years,due to population pressure and economic development, mangrove wetland’s qualityand area are shrinking. The recovery of the mangrove wetland has become a hot topicin the world. Guangdong coastal area is an important distribution area of mangrove forests. Inrecent years, with the continuous development of economy, the increase of populationand the severer of human disturbance, Guangdong coastal mangrove wetlandecosystem has become the high vulnerable ecosystem. It is facing the degradation ofecological systems, biological resource depletion, biodiversity decline anddeterioration of the ecological environment and other serious problems. This hasbecome one of the important reasons of recession of fishery resources in Guangdongcoastal area. Systematic study on the Guangdong coastal mangrove’s marineecological effect and to explore the mechanism of inhibition of carbon sinks, ofgreenhouse effect and degradation of pollutants, can provide effectively reference forrepair the degenerated Guangdong coastal mangrove forest ecological system. This research was conducted to study the8major coastal mangrove distributionarea in Guangdong Province, including Huizhou Dayawan mangrove Park, ZhuhaiQi'ao Island Mangrove Nature Reserve, Shenzhen Futian Mangrove NatureReserve,Chenghai Mangrove area, Raoping Fu Ren Cun Mangrove area, ShuidongBay Mangrove area, Jiangmen Guang Bay Mangrove and Lianjiang Gaoqiaomangrove area.
