摘要
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,对山西大同薛家庄林场不同林分密度的小黑杨人工纯林冠幅尺寸进行估计。结果表明:应用空间统计学半方差函数来分析高空间分辨率影像,可以较为准确地实现对密度相对较高纯林林分冠幅尺寸的估计,随着林分密度的降低,估计误差相应地增大。
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.
