| Abstract: | 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. |
