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,分析了雷州半岛红树林的空间结构。结果表明:1)由样地1→样地2→样地3→样地4,混交度为0.272→0.292→0.158→0.197,样地1和样地2为中度混交,样地3和样地4为弱度混交。2)在空间大小对比上,白骨壤直径大小比数在4块样地都较小,占有较大的优势;红海榄在各样地中都处于劣势和绝对劣势状态;其它树种平均大小比数都在0.5左右,生长上处于中庸状态。3)各样地林分平均角尺度分别为0.61,0.43,0.45,0.63,样地1、样地4的林木分布格局为团状分布,样地2、样地3为均匀分布。

Abstract: Stand spatial structure of Mangrove forest in LeizhouPeninsula was investigated by using three structure parameters(mingling, neighborhood comparison, and uniform angle index-neighboring tree distribution pattern).The results showed that the average mingling in four plots is 0.272, 0.292, 0.158, 0.197 respectively, plots 3and 4 are between moderate mixture, the othersare low mixture; Avicennia marina is dominant at DBH neighborhood comparison, Rhizophorastylosa is suppressed, the others are intermediate; the uniform angleindices of the four plots are 0.61, 0.43, 0.45, 0.63 respectively, which shows the distribution of trees in plots 2 and 3 is in the uniform pattern, and that in plots 1 and 4 is in cluster distribution.

Key words: Leizhou Peninsula, mangrove, spatial structure, mingling, uniform angle index, neighborhood comparison
