Abstract:
This paper studied the restoration effects of Pinus yunnanensis forest, mixed Eucalyptus maideni-Acacia meamsii forest, Eucalyptus maideni forest and restored natural vegetation in middle Yunnan area. The man-made forests consisting of different tree species had different effects on plant diversity, forest hydrology, soil surface erosion control, soil amelioration, and forest characteristics. Afforestation with native species promoted the plant diversity. Recovery Distance Index(RDI) was calculated for the evaluation of the forest restoration extent based on Principal Component Analysis (PCA). The restored natural vegetation P. yunnanensis forest, E. maideni forest, and A. mearnsii-E. maidensi forest would need correspondingly 29.14, 14.36, 34.23, and 11.03 years to recover to the ecological functions of zonal climax community. There were some relationships among forest recovery variables. Shannon-Wiener index, herbage coverage, community evenness, species diversity, soil available K, soil bulk density, biomass of herbage, woody plant coverage, timber volume of woody plant, soil total K, soil erosion, soil Si/V, littersfall, soil non-capillary porosity and through-fall were the main variables among the forest restoration variable dealt with in our work. Diversity played a central role in the restoration of ecosystem structure and functions.
