摘要：桉树人工林是我国南方地区重要的速生用材林,但桉树种植是否会对区域水资源造成较大影响一直存在争议,这主要是由于桉树人工林种植对水文过程的影响机理仍不清楚,缺乏系统的梳理和总结。本文从森林对水文过程的调控作用入手,根据降水在桉树人工林生态系统中的再分配和转化过程,综述林冠层截留、枯落物层拦蓄、土壤层涵蓄和蒸发散等对水文过程的调控作用。结果表明,桉树人工林对水文过程的调控作用主要受到降雨强度、林分结构、土壤特性和植物蒸腾等因素的影响,进而制约桉树人工林水循环过程和水量平衡及区域水资源可持续利用。未来应加强林分结构变化和不同经营管理措施对桉树人工林水文调控作用的影响机制、气候变化条件下不同时空尺度桉树人工林对水文过程的调控机理研究。
Eucalyptus plantations were important fast-growing timber forests in southern China.However,there was much controversy over whether Eucalyptus planting had a significant impact on regional water resources.Upon investigation,this was largely due to the unclear mechanism of the impact of Eucalyptus plantation on hydrological processes,as well as a lack of systematic review and summary.In this paper,from the perspective of the regulation of forest on hydrological processes,the regulation mechanisms of canopy interception,litter layer interception,soil storage and evaporation on hydrological process were summarized according to the redistribution and transformation process of precipitation in Eucalyptus plantation ecosystem.The results showed that the regulation of Eucalyptus plantations on hydrological processes was mainly influenced by factors such as precipitation magnitude,stand structure,soil characteristics and plant transpiration,which subsequently constrained the water cycle process,water balance,and sustainable utilization of regional water resources in Eucalyptus plantations.In the future,the influence mechanism of stand structure change and different management measures on the hydrological regulation of Eucalyptus plantations should be strengthened,as well as to study the regulation mechanism of Eucalyptus plantations on hydrological processes at different spatial and temporal scales under climate change.
