摘要
黄毛青冈群落是滇中半湿润常绿阔叶林的另一个群落类型。群落的总生物量为１３５，９０９ｔ／ｈｍ￣２，其中树干占４８．３６％，枝占１５．４４％，叶占４．５１％，根占２７．７６％，凋落量占３．９３％群落的活生物童为１３０．５６９ｔ／ｈｍ￣２，优势种黄毛青冈占５３．９５％，其它栎类占１６．５８％，其它常绿阔叶树占１８２８％，落叶树占７，１５％，灌木占３．８８％，草本植物占０．１６％。
In this paper,the biomass of Cyclobalanopsis delavayi community of thesemihumid evergreen broad-leaved forest of the central part of Yunnan province at anelavation 2300 m(25°19′N. and 102°33′E.)is studied.The estimated totalhomass of C. delavavi communitv is l35.909t/hm￣2,of which 48.36% is stems,15.44% branches,4.51 % leaves,27.76% roots, and 3.91 % litters.The living biomassof the community is 130.569t / hm￣2,of wich 67. 70 % is overstoery, 28. 24%substorey,3.88% shrubs layer,and 0.16% herb layer.The living biomass percentages ofdominant C. delavayi,other oak, other evergreen broad-leaved species,deciduousspecies,shrubs, and herbs are 53.95%, 16.58%, 18.28%,7.15%,3.88% and0.16%respectivelv.
