摘 要:对帽儿山实验林场4种林分类型(水曲柳纯林、水曲柳落叶松混交林、水曲柳红松混交林、水曲柳云杉混交林)的林下枯落物储量和持水性能进行了研究。结果表明:水曲柳红松混交林的枯落物储量最大(11.2 t/hm2),其后依次为水曲柳纯林(9.7 t/hm2)、水曲柳落叶松混交林(9.3 t/hm2)、水曲柳云杉混交林(7.6 t/hm2);4种林分的枯落物最大持水量依次是水曲柳纯林(21.7 mm)、水曲柳红松混交林(21.6 mm)、水曲柳云杉混交林(16.4 mm)、水曲柳落叶松混交林(16.1 mm)。总体来看,水曲柳纯林和水曲柳红松混交林枯落物持水能力好于水曲柳云杉混交林和水曲柳落叶松混交林。Through the litter amount survey and the water holding characteristic experiment of the litter under four kinds of forest ( pure forest of Fraxinus mandchurica, mixed forest of Fraxinus mandchurica and Lar/x, mixed forest of Fraxinus mandchurica and Pinus koraiensis, mixed forest of Fraxinus mandchurica and Picea koraiensis) in Maoershan experimental farm of Northeast Forestry University in eastern Heilongjiang Province. The result shows that the litter amount under mixed forest of Fraxinus mandchuriea and Pinus koraiensis ( MFFP1 ) is the maximum (11.2 t/hm^2) , the second is pure forest of Fraxinus mandchurica(PFF) (9.7 t/hm^2) , the third is mixed forest of Fraxinus mandchurica and Larix(MFFL) (9.3 t/hm^2), the fourth is mixed forest of Fraxinus mandchurica and Picea koraiensis (MFFP2)( 7.6 t/hm^2). The maximum water holding capacity of litter in PFF, MFFP1, MFFP2 and MFFL are 21.7 mm, 21.6 mm, 16.4 mm, 16.1 mm respectively. The litter lay- ers of PFF and MFFP1 have the better water - holding capacity than MFFP2 and MFFL in Maoershan experiment farm of Northeast Forestry U- niversity in eastern Heilongjiang Province.
