| 摘 要： | 本文报道三沙湾西北部滨海湿地潮间带生物109种,其中多毛类、软体动物和甲壳动物占总种数的89.90%,三者构成潮间带生物主要类群.断面间比较,Sch1断面的种数最少（42种）,Sch3断面的种数最多（73种）.种类季节变化,以春季种数（83种）大于秋季（59种）.三沙湾西北部滨海湿地潮间带生物平均生物量12.45g/m^2,平均栖息密度为368个/m^2.生物量以软体动物居第一位（7.34g/m^2）,甲壳动物居第二位（2.55g/m^2）;栖息密度以软体动物居第一位（196个/m^2）,多毛类居第二位（154个/m^2）.数量垂直分布,生物量以中潮区（15.20g/m^2）大于高潮区（12.37g/m^2）大于低潮区（9.78g/m^2）;栖息密度以低潮区（563个/m^2）大于中潮区（483个/m^2）大于高潮区（56个/m^2）.数量季节变化,生物量以春季（16.69g/m^2）大于秋季（8.21g/m^2）;栖息密度以春季（677个/m2）大于秋季（58个/m^2）.三沙湾西北部滨海湿地潮间带生物按断面和所处的位置可分为3个群落：Sch1泥沙滩群落,高潮区：黑口滨螺-粗糙滨螺带;中潮区：中蚓虫-鸭嘴蛤-秀丽长方蟹带;低潮区：似蛰虫-焦河篮蛤-鸭嘴蛤带.Sch2泥沙滩群落,高潮区：黑口滨螺-粗糙滨螺带;中潮区：才女虫-鸭嘴蛤-淡水泥蟹带;低潮区：似蛰虫-侧底理蛤-鸭嘴蛤带.Sch3泥沙滩群落,高潮区：黑口滨螺-粗糙滨螺带;中潮区：才女虫-鸭嘴蛤-短拟沼螺-弧边招潮带;低潮区：不倒翁虫-侧底理蛤-齿腕拟盲蟹带.结果分析表明：春季Sch1和Sch2群落不稳定,秋季Sch1、Sch2群落和Sch3群落相对稳定,总体显示,三沙湾西北部滨海湿地潮间带生物群落发生扰动,初步分析认为与优势种鸭嘴蛤和优势种才女虫季节演替有关. |

| Abstract: | Species of 109 benthos in intertidal wetlands of Northwestern Sansha Bay ,Fujian Province, are reported in this paper. Polychaetes, Molluscs and Crustaceans occupied 89.90% of all. The species number was the highest at transect Sch3 ,the least at transect Schl ,and the numbers was higher in spring than autumn. The average biomass and density were 12.45g/m^2 and 368ind/m^2, respectively. The biomass of Molluscs was the highest and Crustaceans the second, the Molluscs was the first, Polychaetes the second in the density. In the vertical distribution of the quantity, the biomass was higher at middle tidal zone than that of high, and higher at high tidal, zone than that of low. the density was higher at low tidal zone than middle, and higher at middle than that of high. In the seasonal variation of the quantity, the biomass and density were higher in that of spring than that of. autumn. There were three communities of intertidal benthos of shore wetlands in the Northwestern Sansha Bay, Fujian Province. It was that Schl silt deposit community, Littoraria （Palustorina） melanostoma- Littoraria （Palastorina） articulate at high tidal zone ,Mediomastus sp. -Laternula （Laternula）anatine-Metaplax elegans at middle tidal zone, Amaeana trilobata- Potamocorbula ustulata-Laternula （Laternula）anatine at low tidal zone. that Sch2 silt deposit community,Littoraria （Palustorina） melanostoma-Littoraria （Palustorina） articulate at high tidal zone, Polydora sp. -Laternula （Laternula）anatine-Ilyoplax tansuiensis at middle tidal zone ,Amaeana trilobata-Theora lata-Laternula （Laternula） anatine at low tidal zone. and that Seh3 silt deposit community, Littoraria （Palustorina） melanostoma- Littoraria （Palustorina） articulate at high tidal zone, Polydora sp. -Laternula （Laternula） anatine-Assiminea brevicula-Uca （ Deltuca ） arcuata at middle tidal, Sternaspis scutata-Theora lata-Typhlocarcinops denticarpes at low tidal zone. The results were showed and indicated that community construct |
