黄龙山次生林带状更新与森林防火的研究

A Study on Relationship Between Strip-Type Regeneration of SecondaryForest and Forest Fire Control in Huanglong Mts.

通过对黄龙山油松营林防火措施调查研究表明，次生林地水平和垂直隔带伐迹油松造林，以水平带状作业为宜。它能促进林木生长，使油松林提早郁闭，林下光照强度减弱，温度降低，湿度增大，风速变小，提高了林分抗火能力。

Through the investigation on fier control measures with forest managing technique instands of Pinus tabulaeformis in Huanglong Mouitains, it was found that the horizontal stripplanting on felling lands of secondary forests is much better than that of vertical one. It couldpromote the tree growth crown closure, reduce the sunlight intensity, fall the temperature,increase the humidity and lower the wind speed under the tree crowns, and therefore raiste theresistance to forest fire.
