摘要	Fine root biomass was measured by soil core sampler in four community type on Tibetan Plateau,of which include two coppice of Betula platyphylla and Quercus aquifolioides,one shrub of Salix oritrepha,and one coniferous woodland of Pinus densata.The fine root density were Betula platyphylla of(785.9±290.4)g·m-2,Quercus aquifolioides of(801.0±279.5)g·m-2,Salix oritrepha of(376.0±146.0)g·m-2 and Pinus densata of(431.2±171.1)g·m-2.Result showed that the fine root density of two coppices was significantly higher than that of shrub and coniferous woodland.Dead fine root was 16.2% of the total fine root in Betula platyphylla,and the percentage were about 25% in other three type of forest.Distribution of fine root had the same pattern that high density of fine root appeared at 0～10 cm soil depth.
