摘要
于2010年9月.2011年6月,秋(9月)、冬(12月)、春(3月)和夏季(6月)4次测定海南东寨港红树林沉积物中的叶绿素a和脱镁叶绿酸含量。结果表明,沉积物中叶绿素a、脱镁叶绿酸的水平分布不同采样点差异明显。叶绿素a含量为1.59~6.82μg·g-1,平均值为2.98μg·g-1,随深度增加呈降低趋势。0~2、2~5、5~8cm叶绿素a含量分别为1.59~6.82、0.70~5.93、0.60~4.49μg·g-1。叶绿亲a平均含量的季节变化相似,叶绿素a最高含量,0~2em出现在9月(6.82μg·g-1),2~5和5—8cm均出现在6月(分别为5.93、4.49μg·g-1)。沉积物中脱镁叶绿素酸的分布与叶绿素a的分布一致,含量为1.81—14.22ug·g-1,最高浓度值出现在2011年6月E站(14.22μg·g-1)。
A seasonal investigation was conducted on the chlorophyll-a (Chl-a) and phaeophor- bidea (Pha-a) contents in the sediments of mangroves in Dongzhai Bay of Hainan Province from September, 2010 to June, 2011. There was an obvious difference in the horizontal distribution of chl-a and pha-a in the sediments between different sampling points. The ehl-a content was 1.59-6.82 μg . g-1, with an average of 2.98 μg . g-1 , and decreased with increasing sediment depth, being 1.59-6.82, 0.70-5.93, and 0.60-4.49 μg . g-1 in 0-2, 2-5, and 5-8 cm lay ers, respectively. The average chl-a contents in different sampling points had the similar seasonal variation pattern, with the highest chl-a content in 0-2 cm layer in September (6.82 p,g. g-l ), and in 2-5 and 5-8 cm layers in June (5.93 and 4.49 μg . g-1, respectively). The pha-a in the sediments had the similar distribution trend to ehl-a. The pha-a content was 1.81-14.22 -1 g-1μg , being the highest (14.22 p.g -1 ) at E station in June, 2011.
