晋江河口及泉州湾湿地生物分布特点

泉州湾受晋江河口径流影响很大，导致湿地生物的水平分布与盐度的分布紧密相关．大致分为湾外和外湾种、内湾低盐种、感潮河段咸淡水种．长腕和尚蟹、扁平蛛网海胆和文昌鱼仅分布在外湾或湾外的砂质海底．3种红树植物、互花米草、招潮蟹、弹涂鱼是内湾泥滩的优势种．咸水草是感潮河段咸淡水指标种．河蚬虽是淡水种，也分布在低盐河段．

Distribution of wetland organisms on Jinjiang River mouth and Qunazhou Bay

Since Quanzhou Bay is under the strong influence of the runoff from Jinjiang River mouth, there is a close relationship between the horizontal distribution of wetland organisms and spatial difference in salinity.The wetland organisms are largely divided into outside bay and outer bay species, inner bay low salinity species, and tidal river braclcishwater species. Mictyris longicarpus, Arachnoides placenta and Branchiostoma belcheri are only distributed in the sandy sediments outside the bay and in outer bay. Three mangrove species, Spartina alterniflora, fiddler crabs and Periophthalmus cantonensis are dominant species on the mudflats in inner bay. Cyperus malaccensis is the indicator for tidal river freshwater species. Corbicula fluminea is a braclcishwater species,but also distributes in the river section with low salinity.
