A severe frozen rain and snow disaster stormed on the forest ecosystems of Nanling cordillera two years ago, which caused enormous damage. Trees between altitudes 500m to 1300m were damaged of varying degrees. Degraded habitats urgently need ecological restoring, especially in ecological sensitive areas and important species protection sites. It is very beneficial to plant breeding, growing and ecological self restoration in Nanling region by the reason of its abundant habitat condition, favorable hydrothermal condition and rich species provenance. We take Nanling National Forest Park as an example to expatiate sequent problems of ecosystem degradation resulting from the frozen rain and snow disaster. It is indicated that natural rehabilitation measure is the most effective approach with great human and financial flexibility, which is much better than artificial recovery measure. Main counter methods of developing the self restoration capability are establishing natural restoration sample plots, giving priority to natural recovery with artificial restoration supplemented, dealing with different protected areas distinctively, giving priority to native landscape tree species with timber species supplemented and advancing step by step according to the actual situation in order to meet external environment and condition for natural ecological restoration.
