abstract = {【Objective】The aim of this study was to explore the effects of different management modes on species diversity and carbon sink capacity in the moso bamboo forest ecosystem, in order to provide scientific guidance for better achieving carbon sequestration and sink enhancement goals and promoting sustainable management of the moso bamboo forest ecosystem.【Method】The moso bamboo forest planted with Dictyophora indusiata (PD), the moso bamboo forest with grass splitting and impurity clearing (GC) and the moso bamboo forest with extensive management (EM) were taken as the research objects. The fixed sample plots were set up for field investigation, sample collection and indoor analysis. The species diversity index and carbon storage of moso bamboo forest ecosystem under different management modes were calculated and analyzed.【Result】1) The shrub species of PD and GC were significantly lower than that of EM, while the herb species were significantly higher than that of EM. The Shannon-Wiener diversity index (H), Pielou evenness index (J) and Simpson dominance index (H′) of PD and GC were significantly higher than those of EM, while the Patrick richness index (D) of PD was higher than that of EM and GC; 2) In the carbon storage of moso bamboo forest ecosystem, the soil layer contributed more than 80 % of the carbon, the carbon storage of tree layer accounted for between 10% and 20%, and the carbon storage of shrub, herb and litter layer accounted for less than 1%; 3) There were significant differences in carbon storage of moso bamboo forest forest under different management modes. The ecosystem carbon storage (BFCS) of EM and PD was significantly higher than that of GC. The soil carbon storage (SOCS) of EM was significantly higher than that of PD and GC. The tree carbon storage (BCS) and annual carbon sequestration of PD and GC were significantly higher than those of EM. The litter carbon storage of GC and EM was significantly higher than that of PD; 4) H, J and H′ were positively correlated with BCS, but negatively correlated with SOCS. J was significantly positively correlated with BCS, H and H′ were significantly negatively correlated with SOCS, indicating that in the moso bamboo forest ecosystem, the higher the species diversity and evenness, the higher the tree carbon storage, and the lower the soil carbon storage; 5) The comprehensive scores of species diversity and carbon storage of PD and GC were higher, among which GC had the highest score due to higher species richness and evenness, and EM had the lowest score due to lower species diversity index.【Conclusion】Planting Dictyophora indusiata and splitting grass and clearing impurity in the moso bamboo forest can promote the regeneration of understory herbs, reduce the dominance of shrub plants and carbon storage in soil layer, and improve the species uniformity of understory vegetation and carbon storage in tree layer, which has a positive impact on the species diversity and ecosystem carbon allocation of moso bamboo forest. In addition, the cultivation of Dictyophora indusiata under the forest not only ensures the high species diversity and carbon storage of the moso bamboo forest ecosystem, but also greatly improves the production of moso bamboo, and also creates more considerable economic benefits through the production of Dictyophora indusiata. It is a management mode of moso bamboo forest that is more in line with the sustainable development of society, economy and ecology.}
