    小兴安岭退化沼泽湿地植被恢复技术

    Restoration techniques of degraded swamp in Xiaoxing'an Mountains, northeastern China

    • 摘要: 以黑龙江省友好国家级自然保护区火烧、放牧和垦殖3 种干扰类型退化森林沼泽湿地为研究对象,应用样地 调查法和挖掘法对植物生长指标进行调查,分析不同栽植模式对退化沼泽湿地植被的恢复效果。结果表明:在火 烧干扰湿地中,栽植红皮云杉纯林是最好的植被恢复模式,栽植3 年成活率为89%,其他植被恢复模式的树木成活 率都很低。在放牧干扰湿地中,红皮云杉纯林、落叶松纯林模式和红皮云杉与落叶松混交林的造林模式恢复效果 好,3 年平均成活率分别为94%、79%、85.5%。在垦殖干扰湿地中,栽植红皮云杉、落叶松纯林模式或红皮云杉与 落叶松混交林的造林模式恢复效果好,3 年平均成活率分别为92%、85%、83%。沙棘在3 种退化森林湿地中3 年 成活率均低于36%,不适合在以上的退化湿地中进行培植。因此,在小兴安岭干扰火烧退化湿地、放牧退化湿地以 及垦殖退化湿地植被恢复中,应选择以红皮云杉、落叶松为主的恢复树种。

       

      Abstract: In this study, three types of disturbed (fire, grazing and reclamation) degraded swamps were investigated in Youhao National Nature Reserve. To analyze the recovery effect of different planting systems applied to degraded swamps, plot investigation method and excavation method were used to investigate plant growth index. The results showed that: in fire disturbed swamp, pure spruce (Picea koraiensis) plantation was the best one among seven planting systems, the survival rate of tree was 89% 3 years after planting, and quite low in other planting systems. In grazing disturbed swamp, the recovery effect of the afforestation with either pure spruce or pure larch (Larix gmelinii) or mixed larch and spruce forest was satisfactory, and the survival rates of tree were 94%, 79% and 85.5% respectively. In agricultural reclamation disturbed swamp, the recovery effect of the afforestation with either pure spruce or pure larch or mixed larch and spruce forest was similar to the grazing discurbed swamps with survival rates 92%, 85% and 83% respectively. Seabuckthorn (Hippophae rhamnoides) had lowest survival rates ( 36%) in all these disturbed swamps, it is not a suitable species for vegetation recovery in the degraded swamps in this area. Spruce (P. koraiensis) and larch (L. gmelinii) are the recommended species for vegetation recovery in the degraded swamps in Xiaoxing'an Mountains of northeastern China.
