Abstract

Acacia auriculiformis was introduced to degraded lower subtropical China for vegetation restoration. A longterm case study showed that these trees grew fast and formed forest cover in the degraded land. The leaf area, efficiency of solar radiation utilization, biomass as well as productivity of the forests reached a high level and the soil fertility was improved through nitrogen fixation of tree roots. Acacia auriculiformis communities reconstructed the habitat in degraded areas, which provided appropriate settlement conditions for native species and the whole community was in advanced succession. However, with the development of community structure, A. auriculiformis showed indication of decline gradually due to the changing environment and unsuccessful self-regeneration. They would be replaced increasingly by native species which adapt to the changed habitat.
As exotic species, A. auriculiformis was demonstrated to be a safe and ideal tree for vegetation restoration in degraded lower subtropics. However, it can be considered only as pioneer species and some forest reconstruction measures should be taken to accelerate the process of restoration.
