Land degradation in forest plantations has become a teething problem in forest plantation development. The ways and mechanisms to sustain a long-term productivity in established forest plantations have attracted great interests in agricultural and forestry researches worldwide. The present paper analyses the research progress,pending issues and possible reasons of land degradation in the context of global and domestic forest plantations.
