中文摘要: 沿海近岸海域是地球上单位面积生物生产力最高的区域,是人类利用生物资源的重要基地。近几十年来,快速的经济开发活动导致了沿海海洋生态系统普遍面临着严重环境问题,如何处理人类活动干扰与维护海洋生态功能和保持生物多样性是海洋管理面临的迫切问题。功能多样性是联系生物多样性和生态系统功能的关键性因素,群落生物功能特征和功能多样性能对人类活动干扰产生明显的响应。本研究针对沿岸海洋生态系统受人类活动严重干扰所面临的环境问题,拟通过对福建沿海多个重点海域海洋底栖动物和环境的实际调查和对本实验室所积累的历史资料分析,通过人类活动干扰压力的赋值和计算,从底栖生态系统出发,利用底栖动物的功能特征,找出海洋底栖动物功能多样性随人类活动压力梯度的变动格局和特征,以期为保护近海海洋生物多样性和生态系统管理提供科学依据。

英文摘要: As one of the highest biological productivity per unit area on Earth,the coastal marine region is an important base for biological resources. In recent decades, rapid economic development activities have led to the cosatal marine ecosystem generally facing serious environmental problems. How to deal with the anthropogenic disturbance and maintenance of ecological functions and biodiversity is the urgent problem in the cosatal region for the manager. Functional diversity could respond significantly to human disturbance and is also regarded as a key in understanding the link between ecosystem functioning and biodiversity. Combining with the historical data we had collected, this study will conduct the investigations of the marine macrozoobenthos and its environments in the cosatal marine region in Fujian Province, then quantify anthropogenic pressures based upon best professional judgment, and detect the pattern and variability of functional diversity along an anthropogenic pressure gradient using macrozoobenthic biological traits analysis. This study will provide scientific surpport for the coastal biodiversity protection and ecology management.
