- Abstract:
-
By the methods of field survey and soaking extraction, an investigation on the water-holding capacity of the litters under four main forests (fir forest, spruce forest, larch forest, Pinus armandi forest) was conducted in Bailong River of Gansu. The accumulation amount of the litters under forests ranged from 11.75 t/hm2 to 28.96 t/hm2, and followed the order:fir forest(28.96 t/hm2) > larch forest(16.17 t/hm2) > Pinus armandi forest(14.36 t/hm2) > spruce forest(11.75 t/hm2); the litter, water-holding capacity changed logarithmically with their soaking time, the water-absorption rate of the litter presented a power function with immersing time. The effective retaining amount of the litter decreased in order:fir forest > larch forest > Pinus armandi > spruce forest.
