Abstract:

Using the panchromatic wave band of high spatial resolution remote sensing image——QuickBird as the data source, the crown of pure Populus simonii×P.nigra plantation with different densities in the Farm of Xuejiazhuang Village in Datong, Shanxi, China, was estimated by applying the semivariogram theory of spatial statistics. The estimated results indicated that applying the semivariogram method of spatial statistics to analyze the high spatial resolution remote sensing image might relatively accurately realize the estimation for the crown of pure forest stand with relative high stand density. As the stand density decreased, the estimated error increased proportionally. It is inferred that this study will provide a new method and reference for solving the problem of automated estimation of forest stand crown.
