Study on the Community Structure of Wild Cymbidium faberi and the Spermatophyte Flora in Jingshan County, Hubei

PurposesThe wild Cymbidium faberi Rolfe community in Dahong Mountain, Jingshan County, Hubei Province was investigated in order to provide scientific support for the conservation of C. faberi.

MethodsThe geographical coordinates, altitude, aspect, slope, canopy, coverage, soil type and community species composition of C. faberi were investigated and measured by means of sampling method.

ResultsThere were 44 vascular plants belonging to 31 families and 39 genera in C. faberi community, among which the phanerophyte were the most, the geophytes were the second, and there were abundant lianas and epiphytes among the layers. C. faberi is the dominant species in the lower layer of community. The tree layer is commoner in Cupressaceae Bartling, Fagaceae, Palmae and Pinaceae, and shrub layer is commoner in Rosaceae, Lauraceae and Myrsinaceae. The C. faberi is the dominant species in the lower layer. The floristic characteristics are related to the tropical, subtropical and temperate distribution patterns, and there is an obvious trend of the transition from the north subtropics to the south warm temperate zone.

ConclusionsIt was found that C. faberi was suitable for living in acidic soil with abundant water and heat, scattered light, suitable canopy density, good ventilation and thick deciduous layer.
