摘　　要：采用角尺度、混交度、大小比数对凉水自然保护区平缓地带红松针阔混交林的空间结构进行研究的结果表明,该林分以团状分布为主,主要呈现出强度、极强度混交,单一树种聚集的情况较少,树种间的混交属性差异很大;林木在胸径大小对比上分化程度比较均匀,优势树种株数与劣势树种株数大致相同,针叶树种相对于阔叶树种有优势。This study analyzed the spatial structure of the coniferous-broadleaved Korean pine mixed forest in the gentle zone of Liangshui Natural Reserve using three spatial structure parameters(neighborhood pattern,mingling,and neighborhood comparison).The result showed that: the stand mainly showed clumped distribution;and the stand was mainly under high degree and extremely high degree mixture,besides,the clumped degree within the same species was low and the mingling attributes among species were quite different.;the size of trees differentiation degree was relatively uniform in the comparison of diameter at breast height,the number of dominant tree species was approximated to disadvantage tree species and coniferous species had an advantage over broadleaved species.
