In order to explore the correlation between vegetation and soil in the rocky desertification area of Northern Hubei Province, and provide reference for the comprehensive management of rocky desertification, we took the karst rocky desertification ecosystem in northern Hubei Province as the example, and investigated the plant diversity and soil physical properties and their correlation in different degree of regional rocky desertification environment by the method of sampling field site monitoring and indoor analysis. The vegetation structure in the karst rocky desertification area in northern Hubei is simple, and the spatial structure, plant composition and plant diversity of the community decrease with the increase of the degree of rocky desertification. The intensity is only 13 families, 18 genera and 18 species. The morphological characteristics of plants are closer when the degree of rocky desertification is higher. The main types of vegetation are Myrsine africana, Cotinus coggygria, Caprifoliaceae and Leguminosae with thorns. The physical structure of rocky desertification soil tends to be degraded with the degree of rocky desertification, while the water holding capacity tends to be stable after degradation. The bulk density, dry density and porosity of soil are significantly correlated with plant diversity, among which non capillary porosity is positively correlated with richness and plant diversity, and evenness index is positively correlated with capillary porosity. The total porosity, evenness, diversity, richness and capillary porosity are the key indicators to evaluate rocky desertification based on plant diversity and soil physical properties.
