In order to develop ecological conservation and sustainable utilization of hydrobiological resources in lakes of Huaibei coal subsidence,we need to investigate their structures and functions of ecosystem.We studied the structure and dynamics of phytoplankton assemblages in two small lakes of Huaibei excavating coal subsidence region from March 2005 to February 2007. The result showed that total nitrogen and phosphorous concentrations in Qianlong Lake were higher than in Nanhu Lake. Cyanophytes and Chlorophytes were two dominant groups in Qianlong Lake and Nanhu Lake,occupying 69.8% and 63.3% of annual average total phytoplankton biomass in the lakes respectively,and phytoplankton biomass was obviously lower in Nanhu Lake than in Qianlong Lake.Moreover,cyanobacterial blooms which mainly consisted of Microcystis aeruginosa appeared in summer in Nanhu Lake,while Microcystis sp.and Aphanizomenon flos-aquae which usually occurred in eutrophic lakes were not observed in Qianlong Lake.Apart from nutrition and water temperature,fish filtering and water hardness might be important factors influencing the community succession and seasonal dynamics of phytoplankton in small lakes of Huaibei excavating coal subsidence region.
