Possible impact factors on the significant difference of natural Vatica mangachapoi seedling regeneration between over-logged and secondary forests in Vatica man gachapoi Nature Reserve in Shimei Bay, Hainan Province of China, were analyzed by means of sampling plot investigation, experimental observations and comparative method. A total of 45 sampling plots, 72 seed rain collection nets and 60 1m(2) quadrats in two forest stands were established. The results of variance and correlation analysis showed that litter dry weight was the major impact factor of natural V mangachapoi seedling regeneration between the two stands and there was a very significant negative correlation between litter dry weight and V mangachapoi seedling (R-2 = - 0.478,p <0.01). It is explained why only litter was the major impact factor on V mangachapoi seedling regeneration, rather than other factors.
