Abstract:

Based on the forest growth and structural stability of the fir forest,the pine forest and the broad-leaved 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 broad-leaved 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.

Key words: Cunninghamia lanceolata, Pinus tabulaeformis, broad-leaved forest, marginal zone, core area, coupling effect
