摘要
采用标准样地和样方调查方法,对秦岭林区华山松进行天然更新调查研究。结果表明,以郁闭度在0.3～0.6之间、海拔1200～1800 m、坡向西南时,华山松天然更新良好;林下枯枝落叶层较厚者,幼苗较多,利于天然更新。调查还发现林下松花竹生长普遍,严重影响华山松天然更新,建议该林区应结合天然林保护工程采取一些行之有效的天然更新、人工更新和人工促进天然更新等更新措施,从而达到华山松更新的目的。
Standard sampling plot and sampling methods were used to investigate the natural regeneration of Pinus armandii. The result showed that Pinus armandii are in better regeneration at the closure rate 0.3 to 0.6, elevations at 1 200-1 800 m and with southeast slope. The stand has thick litter layer and abundant seedlings under. The investigation also found that Songhua bamboo grew well and have affected the regeneration of Pinus armandii. Measures should be taken to improve the regeneration of Pinus armandii.
