摘要
按照不同森林类型分别对阴山山地东段大青山水源涵养林进行了生物量及其吸冰量的测定分析。结果表明，白桦次生林的总体生物量最高，为２２８．７ｔ／ｈｍ２；人工油松林为１１４．２ｔ／ｈｍ２；阳坡灌丛为３１．９ｔ／ｈｍ２；阴坡灌木林生物量最小，为２８．２ｔ／ｈｍ２。其吸水量分别是：白桦次生林１４９．８ｔ／ｈｍ２＞人工油松林９５．８ｔ／ｈｍ２＞阴坡灌木林４９．０ｔ／ｈｍ２＞阳坡灌丛２６．８ｔ／ｈｍ２。
According to different forest-type. The analysis have done onthe Biomass and its water absorbing capacity of DaQin Mountains Forest forconservation of water supply in eastern region of DaQin Mountains. The con-clusion is that Batula platyphylla secondary forest has the largest number ofBiomass with 228. 7t/hm￣2. Pinus tabulaeformis plantation with 114. 2t/hm￣2.Shrub forest in north slope has the lcast number of Biomass with 28.2t/hm￣2.The water absorbIng capacity of four kinds of forest-type are that Butulapllatyphylla secondary forest with l49.8t/hm￣2>Pinus tabulaeformis plantationwith 95.8t/hm￣2>shrub forest in north slope with 49.0t/hm￣2>shrub forest in south slope with 26.8t/hm￣2.
