The Investigation of benthic macroinvertebrates in Baiyangdian Lake

The Zoobenthos in Baiyangdian Lake in Hebei province of China were investigated during August to October 2014, including the community structure and diversity. Total of 23 zoobenthic species were collected at 9 sampling sites, including 17 species of mollusca, 2 species of annelida and 4 species of aquatic insects, accounted for 73.91%, 8.70%, 17.39% respectively. The research would reflect the macrobenthos biomass in Baiyangdian Lake, then providing certain theoretical basis for ecological restoration in Baiyangdian Lake. Baiyangdian Lake is the largest wetland in the Haihe river plain, located in the central part of Hebei Province. It is famous for large areas of reed marshes and contiguous acres of lotus Lake, known as the Pearl of North China. Baiyangdian Lake plays an important role in maintaining the ecological system of wetland, regulating climate of Hebei plain and the Beijing Tianjin region, meliorating temperature and humidity conditions, increasing groundwater supply, maintaining the biodiversity and the source of rare species.
