摘　　要：Hubble空间望远镜和 Keck镜投入使用10年来,赖曼α森林的研究取得了巨大进展,使人们对其性质和起源有了新的认识。评述了观测方面的主要成果,包括柱密度、多普勒参数、元素丰度、吸收体形状和尺度、空间分布、演化、与星系的关系等。Since Hubble Space Telescope and Keck Telescope were operated, great progress in studyon Lyman α forests has been made in the past 10 years. The properties and origin of Lymanα forest have been better and better understood. In this paper, the observations on Lymanα forest, including column density, Doppler parameter, abundence, size and shape of absorbers,space distribution, evolution and relationship between Lyman α forest and galaxies, are reviewed.
