| 摘 要： | 于2007～2008年利用遥感影像结合实地核对,全面调查福建沿岸海域互花米草(Spartina alterniflora)的分布.调查结果表明全省沿岸海域互花米草分布面积为99.24 km2,宁德市沿岸海域互花米草的面积最大,达66.29 km2.互花米草已经入侵大多数港湾,其中三沙湾分布面积最大,达62.45 km2,占全省沿岸海域互花米草总面积的62.93%.在13个主要港湾中,互花米草对三沙湾内潮间带滩涂的占有率最高,达20.86%.福建省主要河口海域大多受到互花米草的入侵,分布面积较大的有赛江口、闽江口、晋江口、九龙江口、漳江口海域,入侵面积分别为6.44、5.77、6.64、3.55和2.75 km2.因此,必须采取一些必要的措施减轻或避免互花米草对本地河口滩涂湿地生态系统的破坏.

| Abstract: | Used remote sensing images and field survey, distribution of smooth cordgrass, Spartina alterniflora, was investigated in Fujian coast waters in 2007 and 2008. It finds that total area occupied by the grass was 99.24 km2 in Fujian, where Ningde city has the largest areas （66.29 km2 ） occupied by the grass. The grass invaded almost all bays of Fujian,in Sansha Bay the grass occupied 62.45 km2 , accounting for 62.93% of the areas invaded in Fu- jian. Among 13 main bays of Fujian,the invasion rate of S. alterniflora in the intertidal zone of Sansha Bay was as high as 20.86%. Simultaneously,the grass invaded almost all estuaries of Fujian. The estuaries of Saijiang River, Minjiang River,Jinjiang River,Jiulongjiang River and Zhangjiang River suffered the most with areas lost by 6.44,5.77,6.64,3.55 and 2.75 km2, respectively. In order to protect estuarine wetland ecosystem, actions should be taken to control the spread of S. alterniflora. |
