| 摘 要： | 森林生物量的精确测定,对于全球气候变化和碳循环研究具有重要的意义。为满足区域乃至全球范围的森林生物量制图所需,本文利用航空遥感摄影数据,通过摄影测量技术,建立了一种基于数字树冠高度模型(DCHM)的森林生物量制图方法,并以日本岛根县匹见实验林为研究区,对林区1967-2007年间的森林生物量变动进行了实测。

| Abstract: | It is important to measure forest biomass precisely for global change and carbon cycle research.For the need of regional and global biomass mapping,the paper developed a set of forest biomass mapping based on digital canopy height model(DCHM).The method used aerial photographic data and aerial photogrammetry technique to deduce that DCHM could detect forest biomass change.Selecting Hikimi experiment forest in Shimane,Japan as an example,it used the method to measure the forest biomass from 1967 to 2007. |
