摘 要: 利用角尺度、混交度和大小比数3个林分空间结构参数,分析了特呈岛红树林的空间结构。结果表明:林分的平均混交度为0.66,介于中度混交和强度混交之间;在空间大小对比上,白骨壤的直径大小比数和树高大小比数分别为0.18和0.36,在林分中占有较大的优势;该地林分平均角尺度为0.61,林木分布格局为团状分布。 Stand spatial structure of Mangrove forest in Techeng Isle was investigated using three structure parameters (mingling, neighborhood comparison, and uniform angle index-neighboring tree distribution pattern). The results showed that the average mingling in the stand is 0.66, which is between moderate mixture and strong mixture.Avicennia marina are dominant at DBH neighborhood comparison and height neighborhood comparison.The uniform angle index of the stand is 0.61, which shows the distribution of trees in this stand is clumped distribution.
