摘　　要：在分析海岛生态系统特征和生态压力驱动因子的基础上,指出海岛承受着自然与人为双重压力驱动,在生态系统的生物量、生物多样性、生境破碎度、周边自然环境要素等多方面得到响应,影响其生态功能,致使整个生态失衡而难以恢复,表现为海岛生态压力。This paper is based on the analysis of island ecological characteristics and island ecological safety factors, the paper pointed out that the island under the natural and man-made dual pressures drive many ways to get in the biomass of the ecosystem, biodiversity, habitat fragmentation, the surrounding natural environment elements response affect the ecological function, resulting in the entire ecological imbalance and difficult recovery, showed the island ecological pressure.

关 键 词：海岛 生态特征 生态压力 驱动因子
