Research on Litter Hydrological Properties of Inefficient Forest in Jinyun Mountain
The purpose of this paper is to transform inefficient water conservation forests in Jinyun Mountain, as well as provide a basis for inefficient forest transformation. In this paper, we get forest reserves, maximum water holding capacity, maximum water holding rate and some hydrological parameters of different forest litter types through the waterholding characteristics analysis of three kinds of litter in Jinyun Mountain. The litter reserve of standard plot one is 874.33g/m2, 980g/m2 in standard plot two, and 264.22g/m2 in standard plot three. The maximum water holding rate of undecomposed layer of standard plot one is 183.56％, 177.98％ in standard plot two, and 219.49％ in standard plot three. The maximum water holding rate of semi-decomposed layer of standard plot one is 246.08％, 106.08％ in standard plot two, and 250.88％ in standard plot three. The maximum water holding capacity of undecomposed layer of standard plot one is 684.68g/m2, 557.66g/m2 in standard plot two, and 180.23g/m2 in standard plot three. The maximum water holding capacity of semidecomposed layer of standard plot one is 1167.23g/m2, 707.2flg/m2 in standard plot two, and 456.88g/m2 in standard plot three. The results indicated that the maximum water holding capacity from high to low is standard plot one > standard plot two > standard plot three. The maximum water holding rate from high to low is standard plot three > standard plot one > standard plot two. The water holding capacity of coniferous and broadleaf mixed forest litter is more than coniferous mixed forest litter. It is further illustrates that the more complex stand structure, the more water holding caDacitv of litter will be.
