Ecological defects and countermeasures of Eucalyptus plantation in Fujian Province

Based on the rapid trend of development of Eucalyptus plantations in Fujian Province in recent years,ecological prob-lems of Eucalyptus plantation were investigated.The results of the study,in combination with long-term investigation on Eucalyptus plantation at our field research station,show that ecological defects in the region are not merely due to the biology characteristic of Eucalyptus but are rather driven by undesirable cultural system and management practices.There is therefore an urgent need to draft out a set of feasible cultural systems for improving ecological stabilization of Eucalyptus plantations.Such systems should include choosing suitable tree species,optimizing stand and tree species structure;disseminating methods of controlled burning cutting-blank and limiting soil preparation practices.Restricting residuum logging,scientific fertilization,adopting sound management den-sity and rotation felling are equally very important.
