Abstract:
The forests formed with
Abies species is a unique mountain cold-temperate dark coniferous forest in China. In Qinling mountains, Minshan mountains, Qionglai mountains, Daxiangling mountains, Xiaoxiangling mountains and Liangshan mountains, these are the primitive forest types constituted of the main construction species of
Abies chensiensiensis,
A. f argesii,
A. faxoniana,
A. yunnanensis,
A. longbracteata,
A. fabri, which become important habitats for wild rare animals such as giant pandas. From the perspective of phytogeography, this paper studied the modern geographical distribution pattern of
Abies genus plants, the relationship between
Abies plant communities and the distribution of giant pandas. It also clarified the composition characteristics of
Abies constructive species community and its staple food bamboo sublayer, and the internal relationship between
Abies constructive species forest types becoming the important habitat environment of giant panda. The research results can provide theoretical basis for ecological restoration of degraded giant panda habitat, construction of staple food bamboo base, reconstruction of corridor and passages, and habitat environment construction.
