摘　　要：对湖南省双牌县低海拔地区１２年生的黄柏、杜仲和凹叶厚朴药材林的产量结构进行观测研究，结果表明，３种药材林的林分生物量为５．８０～２０．４５ｔ／ｈｍ２·ａ，净生产量为１．２１～２．８１ｔ／ｈｍ２·ａ．林分生物量、净生产量及主要药用部分于皮的生产力，均以黄柏为最高，杜仲次之，四叶厚朴最低．说明在该立地条件下，黄柏的适应性较强，经济效益亦比其他两个树种更佳．The yield structure of 12-year Phellodendron chinense,Eucommia ulmoides and Magnoliaofficinalis medical forest located in low elevation area of Shangpai County,Hunan,has been ohsery.ed and studeied o The results show that the biomass of forest of three medical species is 5.80～20.45 t/hm2,and that the net biomass is 1.21～ 2.81t/hm2,Among the three species,Phellodendron chinense is the highest species in biomass,in net biomass and in productivity of mainmedical parts of stem and bark,the next is Euconmmia ulmoides and Magnolia officinalis is thelowest. The fact indicates that under this site condition Phellodendron chinense has better adaptability,and can provide more economic benefit.than Eucommia ulinoldes and Magnolia officinalal.
