| 摘 要： | 利用TM数据比较了1993年、2000年和2003年温州沿海互花米草的面积变化,以灵昆岛为例,研究了互花米草引种、繁殖和扩散的特征,并且利用样地和样线对比互花米草与滩涂发育、围垦造陆、海水池塘养殖的相互响应关系.结果显示,温州滩涂互花米草1993～2003年间总面积增加231.99 hm2;互花米草在温州没有形成成熟种子,自然繁殖以根茎为主;在灵昆岛淤长型滩涂上,1993～2003期间互花米草与围垦海堤和海水养殖池塘呈现正响应关系,滩涂淤长速率远大于互花米草,为后者在潮间带中下部扩散提供条件.互花米草对滩涂潮上带的促淤作用明显,因而有利于海水池塘养殖规模扩大,也有利于围海造陆工程.

| Abstract: | Three Landsat images of 1993,2000 and 2003 TM multi-spectral images were used for the mapping of Spartina alterniflora Loisel in the tidal zone of Wenzhou coast.3 vector thematic layers in Wenzhou coast were produced through the repeated GPS field investigations and interface interpretation with ERDAS Imagine 8.5 image processing software,one sample plot and two sample cross sections in Lingkundao Island.The total area of Spartina alterniflora Loisel in three years in the Wenzhou region was 391.53 hm2(in 19... |
