摘要:
受火山活动干扰,长白山各坡向植被演替进程表现出较大差异,东坡植被演替处于早期阶段;而北坡出现岳桦(Betula ermanii Charm.)上侵现象;南坡植被演替处于二者之间。经过多年野外调查对比分析,首次提出长白山西坡苔原带出现小叶章(Deyeuxia.angustifolia(Kom.)Y.L.Chang)侵入苔原的现象。调查显示小叶章呈现从低海拔处向高海拔逐渐侵入的趋势,威胁牛皮杜鹃(Rhododendron chrysanthum Pall.)及笃斯越橘(Vaccinium uliginosum Linn.)等苔原带植物的生存,并导致苔原带景观变化。在调查长白山西坡小叶章侵入苔原带的...
Abstract:
The tundra of Changbai Mountain is the typical temperate Alpine tundra. Due to the volcanic interference, the plant successions of the four slopes were different. In eastern slope, it is at the early stage. While, there is Betula ermanii invasion to tundra zone in northern slope. And plant succession in the south slope is between them. On the basis of plant community investigation, the paper introduced the phenomenon of Deyeuxia.angustifolia invasion to tundra zone. There is a gradually invasive trend of D.angustifolia into tundra zone. The Alpine tundra plants, such as Rhododendron chrysanthum Pall. and Vaccinium uliginosum Linn., were threatened by the invasion. And invasion of D.angustifolia changed the landscape of Alpine tundra. To reveal the reason of invasion, we carried out the experiments of transplant, temperature enhancement and seed germination. The results showed that the effect of simulated climate warming on the growth of D.angustifolia was negative. And seeds of D.angustifolia could not germinated in tundra plant community. Contrarily, it could germinate in bare soil based on volcanic ash. Finally, we draw a conclusion that the invasion of D.angustifolia was the special stage of the plant succession after the volcano eruption, which represented the invasion of Betula ermanii zone.
