Abstract: This paper studies researches on poplar plantation and restoration at home and abroad in recent years, summarizes the main performance of ecological degradation poplar plantations: ecological degradation of poplar plantation is mainly manifested in three aspects: declining soil degradation, drop in productivity and biodiversity. The main reasons leading to ecological degradation are the outbreak of diseases and insect pests, unreasonable human activities and allelopathy of poplar. The authors proposed specific measures to restore ecological poplar plantation and scientific technical countermeasures to realize the ecological restoration of poplar plantation. It is very important to strengthen the management of poplar ecological system, protect biodiversity and regulate forest land productivity to recover ecological benign cycle from degradation of poplar plantation and realize a sustainable management of plantation. This paper can provide the theoretic basis for continuing operations of poplar plantation and scientific evaluation of the ecological environment problems.
