基于高空间分辩率影像的林分冠幅估计

Estimating Forest Stand Crown Based on High Spatial Resolution Image

以高空间分辨率遥感影像QuickBird的全色波段为数据源,应用空间统计学半方差理论,对郁闭度较高的人工白皮松林冠幅尺寸进行较为准确地估计。结果表明:空间统计学半方差方法可以作为郁闭度较高纯林林分冠幅估计的一种有效方法。研究为解决林分冠幅的自动估计问题,提供了一种新的手段与方法。

Using the panchromatic wave band of high spatial resolution remote sensing image-QuickBird as the data source, the crown of plantation White Bark Pine （ Pinus bungeana） with relative high crown closure was accurately estimated by applying the semivariogram theory of spatial statistics. It is concluded that the semivariogram method of spatial statistics may be as an effective means of estimating the crown of pure forest stand with relative high crown closure. This study provides a new way and method for solving the problem of automated estimation of forest stand crown.
