摘　　要：随着遥感技术的不断发展,部分林况因子调查逐渐从传统的人工地面调查转向遥感调查,虽然提高了工作效率和精度,但也存在一些尚未解决的问题。文中系统总结了基于遥感图像的树种、树高、树冠、胸径、位置、郁闭度、年龄、株数、蓄积量、生物量等林况因子目视判读和计算机提取研究的现状及存在的问题,并对今后发展提出了建议。With the constant development of remote sensing technology, remote sensing survey has been more adopted in the investigation of some forest condition factors than traditional artificial ground survey.Although the remote sensing survey improves the work efficiency and accuracy, there are still some problems unsolved. This paper systematically summarizes the present situation and problems of the research on visual interpretation and computer extraction of forest condition factors including tree species, tree height, crown,DBH, location, canopy density, age, number of plants, stock and biomass based on remote sensing images.Some suggestions are put forward for the future research.
