摘　　要：林隙是一种经常发生的小规模干扰,它不仅是森林循环和演替的重要场所,也是森林生态系统时空格局变化的重要驱动力。本文主要从时间(林隙年龄)和空间(林隙面积)两种尺度评价了林隙干扰对更新的影响,并结合光照、温湿度、土壤、地形等环境因子对林隙空间环境异质性问题进行了评述,对近年来国内外研究进展进行了概括,并对目前这一领域研究重点进行总结,为以后的相关研究提供参考。Forest gap, the usually happened interruption in miniature, is a signifi- cant room for forest cycling and succession, and a fundamental motivating force of space-time pattern change of forest eco-systems. This paper was studied the effect of forest interruption on re-generation from the temporal aspect （forest gap＇ s age） and spatial aspect （ forest gap＇ s dimension）, evaluated the impact of environment factor, such as light, temperature environment heterog years, and in order eneity, made to offer some and humidity, soil, landform, etc. , on spatial a brief summary of research progress in these reference for future studies.
