摘　　要：运用逻辑斯蒂模型定量评价了2001年和2010年2个时期闽东滨海湿地生态脆弱性的动态变化.结果表明:2001年和2010年闽东滨海湿地生态脆弱性综合评价指数(V)分别为0.5384和0.5374,均处中度脆弱水平;景观结构还算完整,但自然状态活力衰退,功能水平有一定退化,对外界干扰的恢复力减弱;尽管1993-2001年和1993-2010年期间各单因子指标变化方向和程度各异,但总体而言这2个时期湿地综合生态脆弱性变化程度较小.The coastal wetland ecological vulnerability of eastern Fujian Province in two periods （2001 and 2010） was evaluated dy- namically by using logistic model. The result showed that ecological vulnerability indices in 2001 and 2010 were respectively 0.5384 and 0.5374, which was at the level of moderate ecological vulnerability. It indicated that landscape structure in the area was rela- tively complete, but nature status was influenced in some extent, whose vigor and function had a certain degradation, and the resto- ring ability to resist interference was weakened. Although single factor indices varied in different directions and degrees during the periods of 1993 - 2001 and 1993 - 2010, there still existed a small change of ecological vulnerability in two periods.
