摘要
本文对不同间伐强度林分环境因子的季节变化进行调查分析后认为,林分光照强度、林内温度及土层含水量随间伐强度的增加而有所提高,间伐强度对林分湿度的影响不大。间伐处理对林分环境因子的影响主要体现在生长旺盛的夏季,对休眠期林分影响不大。研究结论可以为落叶松人工林间伐调控理论提供参考。
After the investigation and analysis on the seasonal variation of different thinning intensity environmental factors, this paper indicated that the light intensity, the temperature and soil moisture content increased with thinning intensity in- creased, the influence on forest thinning intensity and humidity was less. Effect of environmental factors on forest thinning was mainly reflected in the vigorous growth of the summer, but influence was less for the dormant period. The conclusion of the study can provide reference for thinning regulation theory of L. gmelinii. Plantation.
