Growth of the second generation E.urophylla between burning and non burning at Gaofeng forest farm of Guangxi has been compared.The results showed that the height and DBH of E.urophylla in non-burning plot were better than burning plot.The stock volume of E.urophylla in non-burning plot increases rapidly,which is more than two times as much as that of the burning plot in the same period.Meanwhile,some side effects occurred in burning plots such as vegetation destruction,significant loss of organic litter and nutrients,increased soil erosion in the young forest which is not conducive to the growth of young forest
