Abstract:: The ‘time-specific method’ and ‘similar system theory’ were employed to construct succession series of the degraded karst communities in Southwest Guangxi. Evaluation indexes such as restoration degree (RD), restoration speed (RS) and their calculating methods were proposed. Variation of RD and RS of community structure and function indexes including community height and biomass were analyzed. The results showed that there were the lowest RD and slower RS at the initial stage of community succession; moderate RD and fastest RS at the mid-stage; the highest RD and slowest RS at the late stage. It would take about 10.7 years at the initial stage, 2.6~3.5 years at the middle stage, and 3.5~5.3 years at the succession end for every 0.1 RD. The normal community structure and function could be presented after 30～40 years natural restoration, but it would take about 100 years to the complete restoration of community structure and function.
