摘　　要：水分效应是混农林业研究的重点内容,对混农林系统结构优化配置与石漠化水土综合整治起着重要的理论指导作用。本文从蒸散效应、土壤水分效应、水分利用效应及截留效应四个方面总结了混农林业研究取得的主要进展,对石漠化治理中混农林业的水分效应进行了分析概述,阐明了石漠化治理区混农林发展的潜力,以及针对混农林系统植被水分利用来源与土壤水分运动规律不清、耗水规律不明、水分利用效率低、混农林配置机理缺乏等问题,对未来混农林业的研究进行了展望,旨在为实现混农林业在石漠化治理中的可持续发展提供参考。Water effect is the key content of agroforestry research.It plays an important theoretical guiding role in the optimal allocation of agroforestry system and integrated regulation of soil and water loss.This paper summarized main progress of agroforestry research from four aspects:evapotranspiration effect,soil water effect,water use effect and interception effect.The water effect of agroforestry in rocky desertification control was analyzed and clarified.The potential of agroforestry development in rocky desertification control area was clarified.The outlook of agroforestry research was put forward to provide a reference for the sustainable development of agroforestry in rocky desertification control for the problems of uncertain origin of vegetation water use and unclear moving principal of soil waterin the agroforestry system,unclear principal of water consumption,low water use efficiency,and lack of allocation mechanism of agroforestry.
