重视桉树人工林生态环境管理，提高科学经营水平

本文在我国桉树人工林稳定发展的新的历史时期，提出从5个方面加强桉树人工林的生态环境管理：加强植被管理，增加林地生物多样性；采取合理的营林措施，既增加桉树生长量，又保护周边环境；做好桉树肥料的施放管理和重金属的检测；及时做好病虫害的预测预报，用生物和物理等防治办法控制病虫害发生；加强伐区管理和林区建设，及时进行迹地更新。从而充分发挥桉树人工林的正面效应，维护人工林的自然生态环境，提高科学经营水平，促进可持续发展。

The Importance of Improving the Scientific Management of Eucalyptus Plantations to Enhance the Ecological Environment

This paper proposed shifting to a new phase in the development of Eucalyptus plantation in China in order to markedly improve the ecological environment associated with Eucalyptus plantations. This shift will require changes to five key aspects of management： 1） strengthening management of competing vegetation and increasing forest biodiversity; 2） implementing a series of methods to increase Eucalyptus growth and protect the surrounding environment; 3） paying more attention to Eucalyptus fertilization and nutritional management and detection of toxic heavy metals;4） prediction and forecasting risks of pests and diseases, including taking appropriate biological, and physical control methods to control pest and disease outbreaks;and, 5） improving the management of harvesting operations. The positive impacts arising from the proposed changes and management interventions would lead to more scientifically based plantation management to the benefit of the natural ecological environment whilst also promoting more sustainable development.
