计划火烧对尚勇子保护区哺乳动物栖息地恢复成效的影响

Research on the Impact of Prescribed Burning to the Mammal Habitat Restoration in Shangyong Sub-reserve

对尚勇子保护区内冷山河区域实施火烧干扰前后哺乳动物对栖息地的利用情况进行监测,分析计划烧除对哺乳动物群落多样性和丰富度的动态影响。结果表明,计划烧除后野生动物群落的多样性、物种丰富度、均匀度均有明显增加,但随着时间的推移多样性指数逐渐恢复到未干扰月份;不同物种在烧除前后被监测到的痕迹数量变化趋势具极大的相似度。研究认为,计划充分和管理完善的火烧间伐在改善野生动物栖息地方面发挥着积极的作用。

This research analyzed the dynamic impact of prescribed burning to the mammals＇ diversity and abundance by continuous monitoring their habitats in Lengshanhe zone of Shangyong Sub-reserve ex- periencing prescribed burning. The results showed that diversity, abundance and evenness of the wildlife community indicated a growth after prescribed burning, but the biodiversity index fell gradually to the un- disturbed status as time went on. The variation tendency of detected traces before and after prescribed burning indicated high similarities among diverse species. The results concluded that well-planned and managed prescribed burning could play an active role in improving and recovering mammal habitat.
