Abstract: The authors analyze the general biodiversity character by field investigations and on some correlated reference data. There are 5 type wetland creatures, such as phytoplankton, zooplankton, zoobenthos, water bird and vascular plant, which have important roles on structure and function of ecosystem of coastal wetland in Jiaozhou Bay. The phytoplankton species belong mainly to widespread species and warm temperate species in ecological type and mainly are diatoms and dinoflagellate, the zooplankton species belong mainly to nearshore low salinity species and mainly are arthropods and coelenterates, the zoobenthos species belong mainly to mid temperate species and widespread eurythermal species. The species of phytoplankton, zooplankton and zoobenthos investigated in 2003 and 2004 are obviously less than the investigation result in 1980s. The water birds in coastal wetlands in Jiaozhou Bay include two types of swimming birds and wading birds, the species belong to Palaearctic Region is main geographical distribution component of the water bird fauna, and the main seasonal types of the water bird fauna are passing bird and migratory bird. In the vascular plant flora of the coastal wetlands, the main life forms are geophyte and annual, the main ecological groups of the flora are hydrophyte and halophyte, and in the flora most seed plant genera belong to widespread type.
