辽河口湿地是我国典型的滨海湿地,在过去几十年受人为过度干扰,植被变化明显。本研究拟通过野外实地调查揭示辽河口湿地植物多样性及功能型的空间格局。结果表明,潮上带的物种丰富度和Shannon-Wiener指数均高于潮间带。与潮上带相比,潮间带的盐生植物与湿生植物比例较高,而中性植物、甜土植物、中生植物与旱生植物的比例较低。物种丰富度、Shannon-Wiener指数以及中性植物、甜土植物、中生植物、旱生植物的比例均随着与海岸线距离的增加而增加,盐生植物、湿生植物比例则与之相反。对所调查样地与植物物种的主成分分析(PCA)表明,潮上带主要为芦苇(Phragmites australis)、刺儿菜(Cirsium setosum...

Liaohe estuary is a typical coastal wetland in Northeast China. Over the past decades, vegetation in this area suffered great change due to human disturbance. The spatial distribution of plant diversity and functional groups was examined in this coastal wetland. Results showed that species richness and Shannon-Wiener index were higher in supratidal zones than in intertidal zones. Compared to supratidal zones, intertidal zones had a higher ratio of halophytes and hygrophytes, but a lower ratio of neutral plants, glycophytes, mesophytes, and xero...
