浙江省岛屿潮间带平均生物量为804.48g/m2,生物密度为698.89d/m2。生物量以甲壳动物居首位,软体动物次之;生物密度以软体动物居首位,次为甲壳动物。生物数量的分布与种类多样性分布的规律基本上一致。生物数量海区的分布是浙南海区>浙北>浙中;不同类型底质的生物量分布是岩礁>砂泥滩>沙滩;不同生境的生物分布是开敞海岸>屏蔽海岸>河口。不同潮区的生物量分布是中潮区>低潮区>高潮区;生物密度是中潮区>高潮区>低潮区,季节分布是春季>秋季。 The average biomass of intertidal islands in Zhejiang Province was 804.48g / m2, and the biomass density was 698.89d / m2. The crustaceans ranked first in biomass and the mollusks were the second, while the creature density ranked first in molluscs and secondly crustacean. The distribution of the number of organisms is basically the same as the distribution of species diversity. The distribution of biomass in the sea area is from the south Zhejiang sea area> north Zhejiang> Zhezhong. The biomass distribution of different types of sediment is rock reef> sandy mudflats> sandy beach; the biodistribution of different habitats is open coast> shielded coast> estuary. The biomass distribution in different tidal areas is in the mid-tide area> low tide area> high tide area; the biological density is in the mid-tide area> high-tide area> low tide area, and the seasonal distribution is spring> autumn.
