Abstract An introduction was given to the current status of the study on biodiversity of plantation forests in the world, and the factors which affected plantation diversity were discussed, meanwhile, the criteria to evaluate and the approaches to increae plantation biodiversity as well as future study direction were put forword. At the present time, there are two contrary study results on plantation biodiversity. One is that compared with native forests, plantation biodiversity shows significant reduction and the other is that plantation biodiversity was not significantly reduced. The two contrary results show that plantation biodiversity is a very complexed problem. And it is not only influenced by plantation age, original condition of plantation site, adjacent natural ecosystems and disturbance, but also by the evalutation criteria of plantation biodiversity. Increase of plantation biodiversity can be realized by remaining native species in plantation site, establishing mixed forests, using proper landscape project and forest management technology and so on. Now studies on plantation biodiversity is relatively fewer and not systematic. In order to resolve the problem, a number of studies, especially internal and international cooperative studies at a large scale is necessary.
