长江口底栖动物功能群分布格局及其变化

The study area is located at the south bank of the Changjiang estuary, China. In there, the changes of habitat conditions of the tidal flat wetland results in the differences of zoobenthic community structure and function along the estuarine gradients. In the study area we set seven transects , namely L (Liuhekou), G (Gaodong ), H (Heqin), C (Chaoyang), B (Binghai), D5 (5th dike of Donghai) and D7 (7th dike of Donghai).
