- Abstract:
-
Maximum water holding capacity, water absorption speed and effective retaining content have been gotten through Surveying and analyzing litter reserves and researching on litter water retention characteristic for pinust abulaeformis,orientalis and robinia in Badaling forest center. Result showed that litter reserves were in the order of pinust abulaeformis(29.2 t/hm2) > robinia(10.3 t/hm2) > orientalis(4.7 t/hm2); maximum water retention capacity followed the sequence of pinust abulaeformis(61.4 t/hm2) > orientalis(57.9 t/hm2) > robinia(43.2 t/hm2); maximum water holdup was in the order of orientalis(471%) > pinust abulaeformis(344%) > robinia(196%); average water absorption speed was in the order of orientalis≥robinia > pinust abulaeformis; effective retaining content was in the order of robinia > pinust abulaeformis > orientalis. In general, water conserving functions of orientalis and robinia were better than pinust abulaeformis, and water retention effect of orientalis showed the best.
