摘要
研究了不同森林类型土壤水分物理性质及土壤水分的渗透值，结果表明：无论是枯枝落叶层，还是０～６０ｃｍ土体层，容重、孔隙度、通气度、毛管持水量以及饱和持水量等表现最优的是白桦次生林林型、土壤稳渗率以人工油松林最大为８．８ｍｍ／ｍｉｎ，白桦林是２．１ｍｍ／ｍｉｎ，阴坡灌林和阳坡灌丛分别是１．８ｍｍ／ｍｉｎ和１．７ｍｍ／ｍｉｎ．
In this paper,we measured the physical characteristics ofthe soil water permeability in different forest-types. The results showed thatthe effects of Betula platyphylla seeondary forest were the best among somemain forest-types,cither on the litterfall water property or soil volume wei- ght,porsity,aeration,capillary water capacity,saturated water capacity in 0-60cm solum,At the meantime,we measured the soil stable permeability speed. The results showed that the soil stable permeability speed of pinus tabulaefor-mis plantation was 8.8mm/min. Batula platyphylla secondary forest was 2.1mm/min shrub in north slope was 1.8mm/min, and the one in sotith slopewas 1.7mm/min, respectively.
