By the relatedness degree of the gray system theory,the relatedness degree between the damages caused by Mikania micrantha H.B.K.to herbaceous community,herbaceous scrub community and shrub community in Guangdong Neilingding Island and the ecological factors was analyzed.The results show that the correlated degree of damages of M.micrantha to herbaceous community and environmental factors is mainly affected by the water content of soil and conductivity.On the other hand,the correlated degree of damages of M.micrantha to herbaceous scrub community and each environmental factor is not significantly different,but it is mainly affected by water content of soil,pH of soil and transparence of communities.There is also no significant difference in the correlated degree between the damages of M.micrantha to shrub community and environmental factors,but it is mainly affected by organic matter content of soil,transparence of communities and water content of soil.The sequence of the effect of all environmental factors on the damage of different communities can be listed as water content>pH and organic matter content> transparence of communities and soil nutrients.
