利用不同尺度的遥感影象数据估测森林采伐面积和采伐量,对于森林资源经营管理十分重要。采用尺度推绎法,对30m分辨率遥感影像、2.5～5m分辨率遥感影像和现场调查资料进行相关性比较分析,并建立相应的数学模型,估测森林采伐面积和采伐量,提高了不同分辨率遥感影像数据的利用效率,为促进森林可持续经营提供理论基础和技术方法。
Using different scales of remote sensing image data to estimate the area of forest harvesting and harvesting is very important for the management of forest resources. Using the standard deduction method, the correlation analysis between 30m resolution remote sensing images and 2.5 ~ 5m resolution remote sensing images and on-site survey data were carried out, and the corresponding mathematical models were established to estimate the logging area and the logging volume, Rate remote sensing image data utilization efficiency, in order to promote the sustainable management of forests to provide the theoretical basis and technical methods.
