- Abstract
Four 0.25-ha natural mixed broadleaf-conifer secondary forest plots (CK, T15, T25, T35) were established in Xiaoxing’an Mountains, PR China. The spatial pattern of plant community was studied by using O-ring statistical analysis method and field survey was carried out to estimate the carbon storage of trees. The research was done in order to explore the effects of different thinning intensities on the spatial and carbon distribution patterns of natural secondary forests in order to provide a reasonable forest management method. We described three main findings. (1) The spatial patterns of either the whole forest or the dominant tree species almost took on a random distribution. Thinning changed the distribution patterns of forest at ≤ 4 m scales, and the distribution changed from random distribution to cluster distribution. (2) It also altered the distribution of dominant tree species, the spatial correlation between dominant species changed from partial negative associations to independence or partial positive associations, and the negative associations in T35 plot were the lowest. (3) The carbon storage in the T15 plot was significantly lower than that in the other plots at ≥ 10 m scales. The carbon storage in the T35 plot was higher than that in the CK plot at almost all scales. In conclusion, the T35 plot optimized the forest structure and it was more beneficial to the carbon storage of natural mixed broadleaf-conifer secondary forests in Xiaoxing’an Mountains after 8 years thinning
