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。

摘  要:
Stand spatial structure of Mangrove forest in Leizhou Peninsula 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 others are low mixture;Avicennia marina is dominant at DBH neighborhood comparison,Rhizophorastylosa is suppressed,the others are intermediate;the uniform angle indices 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.
