%X By the typical plot method, the interference theory and species diversity analysis method, and redundant analysis(RDA), we studied the relationship between 11 environmental factors and the diversity of revetment forest species, and explored the different disturbances of human disturbance to the Wenjiang section of the Jinma River. The impact of species diversity and soil physical and chemical properties on revetment forests. The results showed that:(1)Among the 264 different levels, 122 species of plants were recorded, belonging to 65 families and 102 genera, of which the herbaceous layer had the largest number of species, with 89 species, accounting for 73% of the total records, with the increase of human disturbance intensity. The number of species is gradually decreasing; (2)Human disturbance has a negative impact on the species diversity level of the Jinma River revetment community. With the increase of disturbance intensity, the Shannon-Wiener diversity index(<i>H</i>) and species richness index(<i>D</i>) of the community are gradually reduced, and on the arbor layer the species composition is single, resulting in a decline in community environmental function and stability; (3)The pH value of the soil in the community was alkaline, and the soil organic matter content was high. The physical and chemical properties of the soil under different disturbance intensity were significantly different(<i>P</i><0.05); (4)Soil water content, available potassium and organic matter content are the most important factors affecting the species diversity of revetment forests.
