Forest Gap Characteristics of Schima superba Caused by Snow Disturbance

Abstract:

Distribution, formation ways and seedlings regeneration characteristics of forest gaps were studied on Schima superba forest after the snowstorm disturbance in Jianglang Mountain, Zhejiang Province, which would provide scientific basis for the community regeneration and post-disaster recovery. The results showed that: the forest gaps area with 50~100m² of most expanded gaps occupied the highest percentage in number (45.0% of the total), which also occupied the highest percentage in size (30.3% of the total), while the canopy forest gaps area of 25~50m² occupied the highest percentage in number and size (50% of the total and 36.39% of the total). The most important way of forest gaps formation was breakage on trunk, and the secondly important way was uprooting. In different sizes forest gaps, regeneration density of Schima superba showed a single peak changes with the increasing of forest gaps size and the regeneration density of the middle area forests gaps was most.
