In order to investigate the macroinvertebrates community structure and the ecological niche characteristics of the dominant species in the Heilongjiang Zhongyangzhan Black-Billed Capercaillie National Nature Reserve, 19 sampling sites were set up in three major rivers (Shizhan River, Shiwulixiao River, and Wodu River) entering the Nenjiang River in the Reserve, and macroinvertebrates samples were collected and the physico-chemical factors of water quality were monitored in the spring, summer and autumn, respectively in 2022. The Shannon-Wiener index and Pianka overlap index were used to analyze the niche of the dominant species of macroinvertebrates species. Redundancy analysis and non-metric multi-dimensional scale analysis were used to analyze the correlation between macroinvertebrates feeding functional groups and physicochemical factors of water bodies and the variability between different river communities.The results showed that 94 species (genera) of macroinvertebrates were identified, belonging to 3 phylums, 5 phyla, 15 orders and 46 families, and there were seasonal differences in macroinvertebrates species richness and feeding function groups, while the seasonal differences were not significant in the Shannon-Wiener index, the Margalef index and the Pielou index. The dominant species of macroinvertebrates in the Shizhan River, Shiwulixiao River and Wodu River were 10, 6 and 3 species, respectively, all belonging to narrow ecological niche species, among which one species of Procladius sp. was the dominant species common to the three rivers. The ecological niche overlap values between the dominant species of the Shizhan River and the Shiwulixiao River were relatively broad, and the ecological niche overlap values of the Wodu River were more concentrated. The main physico-chemical factors of water quality affecting macroinvertebrates feeding function groups were nitrate ion content, transparency, water temperature, pH and dissolved oxygen content. The results of the non-metric multidimensional scale showed that the macroinvertebrates community structures of the three riverine rivers had high similarity.
