卧龙大熊猫生境的群落结构研究

系统样方调查，研究了卧龙大熊猫生境的物种结构与群落特征。结果表明，大熊猫原 始生境群落特征表现为微个样方内的物种数平均为２１．５７个，盖度为１．６４，物种多样性指数为１．５７，优势度指数０．３８，最大平均树径达７９．４ｃｍ，平均每平方米竹类生物量为６．７３ｋｇ。大熊猫对生境的群落结构也有较广的适宜性，在卧龙落叶直林， 叶－针叶混交林及针叶林３种植被型均可为它的适宜生境。但生境适宜性程度及生境质量主

Community structure analysis of giant panda habitat in Wolong

Giant panda inhabits the cool temperate and subalpine forest in Wolong,China.The important values of the habitat were expressed as the follows:the species richness is 21.6,canopy coverage is 1.64,Shannon species diversity index is 1.57,Wilson species dominance index is 0.38,maximum DBH is 79 4cm,and biomass of bamboo is 6.73kg/m 2. In Wolong,the evergreen broad leafed forest,evergreen and deciduous broad leafed forest,deciduous broad leafed forest,coniferous and deciduous forest,subalpine coniferous forest are the suitable habitat for pandas.However,their suitability and habitat quality are influenced by deforestation.The species dominance and DBH ,as well as bamboo biomass and generation index are higher in the primary habitat than those in the disturbed habitat.The species richness and diversity of habitat are found higher in the disturbed ones.
