摘　　要：介绍了随着桉树人工林的广泛种植,其对林区生态功能和水源地安全的影响逐渐引起人们的重视。分析了桉树林开垦及经营过程对林区水体水质的影响,包括对水源涵养功能的影响,降雨条件下对林区水质的影响,以及施用化肥对水体和土壤的影响等;进一步论述了桉树渗出液对生态环境的风险,包括其化感作用、进入水体的途径和对饮用水安全的危害。系统总结了桉树林区及其分泌物对生态环境和水体安全构成的风险,为桉树林区管理、污染防治和水源地风险控制提供科学参考。With extensive planting of eucalyptus plantation forest, the influence on the ecological function and water source in the forest area has gradually aroused public attention. Effect of the process of cultivation and management of eucalyptus plantation forest on water quality in the forest was analyzed and studied, including the influence of water conservation function, effect of rainfall on water quality in forest region, and the effect of applying chemical fertilizer on water and soil. The risk of the ecological environment of eucalyptus exudates, including the allelopathy, the way of entering the water body and the risk of drinking water, was also discussed. The risk of the ecological environment and the safety of water body were summarized. All of these could provide scientific reference for the management of eucalyptus forest, pollution control and risk control of water source.
