摘　　要：对秃杉混交林及秃杉纯林的地上部分持水能力及土壤孔隙度、渗透性能及持水能力等土壤物理性质的研究结果表明 :秃杉混交林的水源涵养能力优于秃杉纯林 ,其中以秃杉杉木檫树混交林最好 ,其土壤稳渗速度和稳渗系数分别为 44.1和 2 6.4mm· min-1,林分总持水量达1 0 97.33t·hm-2 .其它依次为秃杉杉木混交林 >秃杉纯林 >An investigation on the water holding capacity of the canopy and the soil properties,such as soil porosity,permeability and water maintaining capacity,was carried out to compare the water conservation function of mixed Taiwania flousiana stands and pure stands The result showed that the mixed stands had stronger water conservation capacity than pure stands The mixed forest of T flousiana,Cunninghamia lanceolata and Sassafras tsumu Hemsl had the best water conservation function,of which the soil permeability coefficient and permeating speed was respectively 44 1 and 26 4 mm·min -1 , and the total water holding capacity was 1 097 33 t·hm -2 The mixed stands of T flousiana and C lanceolata, the pure T flousiana stands,and the pure C lanceolata stands were followed by
