Abstract: By field investigation on the damaged forests in Guangxi ice storm disaster area, the relationship betweenforest disaster and some factors such as tree species, slope aspect, altitude. The results of investigation showed thedisaster tolerance ability of various tree species followed the order of Cam ellia oleifera > Illicium verum >Cunningham ia lanceolata > Pinus m assoniana > Euca lyptus > Phyllostachys pubescens, and the tolerance ofindigenous specieswere stronger than that of foreign species. The influence of altitude on disaster degree showed anS2shaped curve, the disaster became heavier with the height of altitude, the disaster was heavier in shaded slopethan in sunny slope, and in pure forests than in mixed forests. Itwas found that the p ine tree after resin-tapped wasdamaged heavier than thatwithout tapped. Based on investigation, the authors suggest: (1) to selected tree specieswith stronger cold-resistance and stress-tolerance; ( 2) to develop indigenous tree species; ( 3) to develop mixedforest; (4) reasonable allocating and management; (5) to take necessary restoration measures.
