<p>Clonal integration not only changes underground soil resources but also significantly influences the evolution of surface plant communities, which is crucial for karst vegetation restoration. This study measured the main nutrient indicators of <i>Loropetalum chinense</i> rhizosphere soil at different stages, and investigated the impact mode of clonal integration on the nutrient status of rhizosphere soil, as well as its influence on nutrient supply capacity during vegetation succession. From early to late stages, compared with non cloned plants, clonal integration leads to a decrease in carbon, nitrogen, and potassium content in the rhizosphere soil of the mother plant and ramets, while the content of available phosphorus in the soil increased. The C\N, C\P, and N\P in the rhizosphere soil of plants undergoing clonal integration were higher than those in the rhizosphere soil of non-cloned plants. According to the GLM (Generalized Linear Model), clone integration was one of the key factors affecting the phosphorus content in rhizosphere soil. We further found that clonal integration alleviated the limitation of vegetation growth in karst areas to soil phosphorus.</p> Graphical Abstract <p></p>
