采用样方调查法,对莲花山白盆珠自然保护区吊皮锥(Castanopsis kawakamii)群落的物种组成、属的地理成分、群落结构及种群结构特征进行研究。结果表明,在3个400 m2的主样方中,共记录了维管植物71种,隶属于32科45属,以茜草科(Rubiaceae)、樟科(Lauraceae)、壳斗科(Fagaceae)和山茶科(Theaceae)为优势科,以大节竹(Indosasa crassiflora)、吊皮锥和革叶铁榄(Sinosideroxylon wightianum)为优势种,吊皮锥种群均为中树或大树,林下缺乏幼苗小苗;在其他12个副样方中均未见到吊皮锥个体,反映了吊皮锥种群为衰退型。基于研究结果提出了吊皮锥资源保护及可持续发展的建议。
The species composition, geographical composition, community structure and population structure of Castanopsis kawakamii community in Baipenzhu Nature Reserve in Lianhua Mountain were studied by means of quadrat investigation. The results showed that 71 species of vascular plants were recorded in three main quadrats of 400 m2, belonging to 45 genera in 32 families. Rubiaceae, Lauraceae, Fagaceae, Theaceae is the dominant species, Indosasa crassiflora, Trichosanthes and Sinosideroxylon wightianum are the dominant species. The population of Trichosanthes pyrenoidos are both middle-sized trees and large trees. The understory lack of seedlings No seedlings were found in the other 12 sub-samplers, which reflected that the population of Pyrus pyrifolia was recession-type. Based on the research results, the suggestion on the protection and sustainable development of the derricks are put forward.
