Abstract：To comprehend the structural traits of the mangrove periphytic algaecommunityand itsassociation with soil environmental factors，the current study was conducted in January 2025 and May，August，and November 2025 at 17 sites within the mangrove forests of Longgang City，Zhejiang Province，and Cangnan County，Zhejiang Province.A total of 212 species of algae were gathered from 54 genus belonging to 5 phyla （encompassing variants），in which 43 genus belonged to Bacillariophyta，5 genus belonged to Chlorophyta， 4 genus belonged to Cyanophyta，and 2 genus were Euglenophyta and Pyrroptata.Further analysis indicated that thedominant algal species in the study area was Bacillariophyta. The biodiversity indices of the living algae wereanalyzed through the biodiversity index（ H′ ），theevenness index （J′） ，and the richnessindex（ ∇[D′）The results indicated that the mangrove area of Laolin（LL）was under severe disturbance during spring and summer，while all monitoring stations were under mild disturbance during winter.Redundancy analysis（RDA） results showed that salinity，total organic carbon（TOC），temperature，and total phosphorus（TP）were the primary environmental factors influencing the community structure of epiphytic algae in the study area.
