摘要:
佛体表面植被多样性及其空间分布特征不仅可以一定程度上表征植物侵蚀岩体的过程,而且对于乐山大佛景观保护与修复具有重要的实践意义。依托2018-2019年乐山大佛修缮工程,系统调查了乐山大佛佛体不同部位植物多样性特征,采用优势度、重要值、ɑ多样性指数、主成分(PCA)分析和系统聚类等方法对其进行了空间异质性分析。研究结果表明:乐山大佛佛体表面高等植物总覆盖率约70%,其中苔藓植物和维管植物分别占植被总盖度的27.5%和72.5%;共发现维管植物25科38属41种,其中草本植物占73.17%。相对于佛体其它部位,左臂植被盖度最高达80%,头部及左右脚两处植被盖度最低(小于1%);根据ɑ多样性指数分析,佛体右腿的Shannon -Weiner指数和Margalef丰富度指数最高,头部Pielou均匀度指数最高,左腿的Simpson优势度指数最高。此外,系统聚类方法表明佛体左右两侧物种具有明显的差异,且左右两侧物种各自的相似度较高,意味着旅游活动对佛体表面植物多样性具有重要的影响。这些结果为乐山大佛佛体表面修复与保护方案的制订提供了基础资料,也为更好的管理乐山大佛及相似露天石刻景观提供了一定的科学支撑。
Abstract:
The vegetation diversity and spatial distribution of the Buddha body surface can not only partly represent the erosion processes of plant to rock, but also play an important role in protecting and repairing the Leshan Giant Buddha. Based on the renovation project of the Giant Buddha during 2018 - 2019, the characteristics of the plant diversity in the different parts of the Giant Buddha were completely investigated, and the spatial heterogeneity was analyzed using the methods of calculating dominance and importance values, diversity index, principal component (PCA) analysis and systematic clustering. The results showed that the total vegetation coverage of advanced plants was about 70% on the surface of the Giant Buddha , of which the moss and the vascular plants accounted for 27.5% and 72.5% of the total vegetation coverage. There were 41 species of the 25 families of the vascular plants, of which the herb accounts for 73.17%. Compared with other parts of the Buddha body, the highest vegetation coverage with 80% was observed on the left arm , while the lowest coverage less than 1% was detected on the head and the left foot . According to the ɑ diversity index analysis, the Shannon -Weiner index and the Margalef richness index showed the highest values on the right leg of the Buddha body, the highest Pielou evenness index on the head , and the highest Simpson dominance index on the left leg . In addition, the systematic clustering displayed obvious differences of the species between on the left and right sides of the Buddha body, and the similarity was found in the species on the left and right sides, implying that the tourism activities may primarily influence the plant diversity of the Buddha body. These results can provide basic information in the restoration and protection of the Giant Buddha, and also provide scientific data in managingthe Giant Buddha and some other similar open-air stone landscapes.
