symmetric neighborhood

Four edge correction methods of the buffer zone,the 8 neighborhood reflection,the 8 neighborhood translation and the distance determinant method of the 4 th neighborhood on the neighborhood were compared with mingling index and angle index of tree spatial structure parameters and the ratio of the trees taken part in the calculation.

选择1块100m×100m的实地调查样地并设置10块100m×100m的模拟样地,从空间结构参数大小比数、混交度和角尺度以及参与计算的株数比例等方面对距离缓冲区、8邻域对称式、8邻域平移式和第4邻体距离判定法这4种边界校正方法进行比较。
