Abstract To explore the seasonal succession and drivers of phytoplankton communities in Guanzhong, Shaanxi Province, China, the water quality and phytoplankton communities in two typical waterbodies (Juehe Wetland Park in Xian and Xiaoxihu Lake in Xianyang) were monitored from 31 August 2017 to 31 July 2018. We identified 43 genera of phytoplankton from 7 phyla in Juehe Wetland Park and 45 genera of phytoplankton from 7 phyla in Xiaoxihu Lake. Phytoplankton communities in the two waterbodies showed significant patterns of seasonal succession. Cyanophyta (Microcystis spp.) dominated in August–September 2017 in Juehe Wetland Park, and Bacillariophyta (Navicula spp.) dominated in October 2017–July 2018. Cyanophyta (Microcystis spp.) dominated in Xiaoxihu Lake in August–November 2017, and Bacillariophyta (Synedra spp.) dominated in December 2017–July 2018. Redundancy analysis (RDA) showed that the temperature and total phosphorus were closely related to the seasonal succession of Cyanophyta and Bacillariophyta. In addition, the temperature, dissolved total phosphorus, and total phosphorus were closely related to the seasonal succession of Microcystis spp., Navicula spp., and Synedra spp. Keywords Phytoplankton .

Introduction Phytoplankton are the main primary producers in aquatic ecosystems (Reynolds 1984), and play a vital role in the food chain, and are important in the maintenance of biodiversity (Dickman et al. 2008). A phytoplankton community can also reflect the quality of the water environment and, to a certain extent, the stability of aquatic ecosystems (Sidik et al. 2008). It

is clear, therefore, that the spatial and temporal changes in phytoplankton community composition, and their drivers, are important reference points in the scientific management of the water environment. As human societies and economies continue to develop, the increasing demand for water in the landscape has promoted the development and construction of artificial lakes. The stability of artificial lake ecosystems and the maintenance of landscapes are important as
