摘要:
自"5·12"特大地震以来，银厂沟谢家店滑坡体至今已形成10年，10年间研究小组运用样方法在滑坡体上设立了9个样地，调查样地植物物种的生长状况，并对样地植物群落结构、植物优势种、植物多样性进行了数据研究分析，研究结果如下：（1）2009-2018年滑坡体植物总种数由53种增加到92种，其中乔木由0种增加到12种，灌木由4种增加到38种，草本先从49种增加到65种，再减少到42种，植物群落由以草本为主的单一结构向完善的乔灌草结构转变，植物物种恢复显著。（2）在植被恢复期间，植物群落优势种类型经历由早期毛葡萄-醉鱼草，到植被恢复初期桤木-灰白毛莓-木贼，再到植被恢复后期桤木-腊莲绣球-芒萁的植物演替变化过程。（3）经过10年的恢复，在总体上Margalef丰富度指数Ma由2.80上升到6.06；Shannon-Wiener指数H’由2.18上升到3.13；Simpson指数D由0.88上升到0.93；Pielou均匀度指数E由0.13上升到0.93，植物多样性逐年上升。研究揭示了震后10年来滑坡体植物物种、植物群落结构、植物多样性在恢复过程中的特征与变化，为震后植被恢复的相关研究以及水土保持工作的开展提供参考与借鉴。
Abstract:
Since the ‘5·12’ mega-earthquake, the landslide on Xiejiadian in Yinchanggou has formed for 10 years. In the past 10 years, on the landslide, we had set up 9 plots by using the sample method to investigate the growth status of plant species. And the data of the plant community structure, plant dominant species and plant diversity were studied and analyzed. The results are as follows. (1) During the period from 2009 to 2018, the total number of plant species increased from 53 to 92, the number of species of trees increased from 0 to 12, the number of shrub species increased from 4 to 38, the number of herbaceous species increased from 49 to 65 and then decreased to 42. The plant community changed from a single structure dominated by herbage to a complete structure of arbor, shrub and grass. The recovery is significant. (2) During the vegetation restoration, the dominant species of plant community underwent a process of plant succession. It changed from the early Vitis heyneana-Buddleja lindleyana type to the initial Alnus cremastogyne-Rubus tephrodes-Equisetum hyemale type, and then to the late Alnus cremastogyne-Hydrangea strigose-Dicranopteris dichotoma type. (3) After 10 years of recovery, the Margalef richness index increased from 2.80 to 6.06 in general; the Shannon-Wiener index increased from 2.18 to 3.13; the Simpson index rose from 0.88 to 0.93; the Pielou evenness index from 0.13 to 0.93. The plant diversity had increased year by year. This study reveals the characteristics, the dynamics of landslide plant species, plant community structure and plant diversity during the recovery process in the past 10 years after the earthquake, and provides the reference and reference for the related research on vegetation restoration after earthquake and the development of soil and water conservation practices.
