Abstract  The taxonomical research on Gomphonemaceae was done in this paper. The light microscope and the scanning electron microscope were used for observation. Algae samples were collected from northwest, southeast and southwest of Heilongjiang Province. Samples were collected from Nanweng river wetland, Sanjiang plain wetland, Qixing river wetland, Zhalong wetland, Naoli river wetland, Anxing wetland, Xingkai lake wetland. The climate zones of these locations included cool monsoon climate zone, temperate humid monsoon climate zone, and semi-humid monsoon climate zone. The habitat mainly included wetlands, rivers, swamps, ponds and streams in Heilongjiang province. All these species were cosmopolitan freshwater species, and the morphological characters were described in this paper based on both LM and SEM observation. Four species are Gomphonema acuminatumEhrenberg, Gomphonema augur Ehrenberg, Gomphonema constrictum Ehrenberg,  and Didymosphenia geminata (Lyngbye)Schmidt.
