摘  要：
以大熊山国有林场杉木林、松类林和阔叶林3种林分类型边缘区和核心区的林分生长量和结构稳定系为研究对象,并选取相关序参量构建2个不同林分间相互作用的耦合模型,探究林场3种林分类型间的耦合程度。结果表明:1)3种林分类型边缘区的林分生长量略大于核心区的林分生长量;2)3种林分类型中杉木林和松类林边缘区的平均灌木层多样性及均匀性均高于核心区,而3种林分类型中的平均草本层多样性及均匀性状况正好相反;3)3种林分类型均存在一定程度的耦合效应,其中松类林和杉木林对阔叶林均具备相对较大的的耦合效应,而这两种针叶林相互之间的耦合效应则相对较小。建议林场在杉木林和松类林的纯林区域适当改植阔叶林以进一步优化林分空间结构,提升林场的生态功能。

摘  要：
Based on the forest growth and structural stability of the fir forest,the pine forest and the broadleaved forest in the Daxiong mountains,the relative order parameters were used to construct a coupling model of interaction between two different forest stands to study the coupling effect among the three forest types. The results showed that:( 1) The forest growth of the three forest types was slightly higher than that in the core area;( 2) The average shrub layer of the fir forest and pine forest and the average herbaceous layer diversity and uniformity of the three forest types were opposite.( 3) There were some coupling effects in the three forest types,And Cunninghamia lanceolata has a relatively large coupling effect on broadleaved forests,and the coupling effects of these two coniferous forests are relatively small. It is suggested that the forest farm should properly replant the broad-leaved forest in the pure forest area of Chinese fir and pine forest to further optimize the spatial structure of the stand and enhance the ecological function of the forest.
