Abstract
Based on the investigation and analysis of plot data,the community characteristics and litter hydrological effects of Quercus liaotungensis,Pinus tabulaeformis,and Pinus tabulaeformis f.shekannesis forests in Ziwuling region were studied preliminarily. Results from the study show that (1) the Quercus liaotungensis forest in Ziwuling Mountains is the single-priority community in general. The Pinus tabulaeformis forest and Pinus tabulaeformis f.shekannesis forest in Ziwuling Mountains are the single-priority community mixing with a small number of broad-leaved species. (2) The Pinus tabulaeformis species are abundant and evenly distributed,Pinus tabulaeformis f.shekannesis forest has the smallest species,and the plant diversity indexes of tree layer,shrub layer,and herbage layer are in the order from low to high. (3) The litter of Quercus liaotungensis forest accounted to 32.65 t/hm2; the litter of Pinus tabulaeformis forest,48.95 t/hm2; and the litter of Pinus tabulaeformis f.shekannesis forest,47.30 t/hm2. (4) The maximum water holding capabilities of the Quercus liaotungensis litter,Pinus tabulaeformis litter,and Pinus tabulaeformis f.shekannesis litter are 50.93,70.15,and 61.68 t/hm2,respectively.
