| 摘要: |
| 2008年冬,南岭林区遭遇特大雨雪冰冻灾害,使得该区森林生态系统遭受极大破坏。灾后及时采取了清理大量枯落物等恢复措施。研究结果表明,经过3年的恢复期后,该区林分及其生物多样均有所恢复。冰灾后形成的林窗区使得各种植物萌发,改善了林分结构,从而使森林生态系统得到修复和重建,也使生物多样性比冰灾前更为丰富。种群数和种群密度则比冰灾年增加57.13%和30.77%。因此,本研究表明,虽然冰冻灾害会对森林生态系统产生严重影响,只要恢复措施得当,灾后的生态系统或会更加优化。 |

| Abstract: |
| The Nanling forest district suffered large ice damages in the winter of 2008, which further destroyed the forest ecosystem in this region. After this ice damage, several restoration measures e.g., cleaning litter, were carried out. Results of this study indicated that stands and biodiversity in the study region were partly restored after restoration stage of 3 years. These phenomena could be explained as follows. Forest gaps, formed by ice damages, improved structures of stand and made kinds of plants growing. Finally, the forest ecosystem was restored and reestablished. The biodiversity was more abundant after ice damage than that before ice damage. Population number and population density in this region were increased by 57.13% and 30.77%, respectively, when compared to that before ice damage. Thus, this study shows although ice damage would have serious influences on forest ecosystems, they could also be restored when suitable measures were performed. |
