- Abstract:
-
Hydrological functions of three hydrological function layers of four forest types were investigated in forest stands of rocky and earthy area in Beijing. The traditional measurement methods were used to monitor throughfall, stemflow, interception loss, hydraulics parameters of forest litter and soil. The results indicated that the interception capacity of different vegetation was significantly different, with the maximal canopy interception of stand of mixed Platycladus orientalis (L.) Franco and Cotinus coggygria Scop. (29.1%), followed by stands of Platycladus orientalis (L.) Franco, Pinus tabuliformis, Acer truncatum. The stem flow ratio of stand Pinus tabuliformis was the highest (5.83%), which fitted the results obtained in arid and semi-arid region well. At the monthly scale, the maximal interception ratio appeared in June, followed July, August, October and May, and there was a positive correlation between interception and rainfall. The forest litter quantity of four stands ranged from 26.3 t/hm2 to 246.0 t/hm2, and the forest litter quantity of stand Pinus tabuliformis was much greater than the others (p < 0.05),followed by stands of mixed Platycladus orientalis (L.) Franco and Cotinus coggygria Scop., Platycladus orientalis (L.) Franco and Acer truncatum, as the same order of the maximum water holding capacity and available interception amount of forest litter. The soil porosity and Ks of stand of mixed Platycladus orientalis (L.) Franco and Cotinus coggygria Scop. were greater than the other stands with the influence of material composition, mechanical composition, root, etc.
