- Abstract:
-
A pilot study of hydrological effects of litter and soil layer was carried out in nine forest types in Bayingzhuang forest farm. The results showed:(1) the total storage capacity of litter was about 5.79~24.97 t/hm2, which decreased in the order:Betula platyphylla Suk. pure forest > Betula platyphylla Suk.-Populus davidiana mixed forest > Pinus tabuliformis pure forest > Populus davidiana pure forest > Quercus mongolica pure forest > Larix principis rupprechti-Pinus tabuliformis mixed forest > Betula platyphylla Suk.-Betula davurica mixed forest > Larix principis rupprechti pure forest > Larix principis rupprechti-Betula platyphylla Suk. mixed forest; (2) there were some differences in water holding capacities of litter in 9 forest types, which decreased in the order of Betula platyphylla Suk.-Populus davidiana mixed forest > Populus davidiana pure forest > Pinus tabuliformis pure fores > Betula platyphylla Suk. pure forest > Betula platyphylla Suk.-Betula davurica mixed forest > Larix principis rupprechti-Pinus tabuliformis mixed fores > Quercus mongolica pure forest > Larix principis rupprechti-Betula platyphylla Suk. mixed forest > Larix principis rupprechti pure forest; (3) water holding capacity and soaking time had the significant logarithmic relationship, the correlation coefficient was above 0.95; the relationship between absorption rate and soaking time could be described by power function, the correlation coefficient was greater than 0.90; (4) the modified interception amount of Quercus mongolica pure forest was the strongest, which was 52.63 t/hm2; the modified interception amount of Larix principis rupprechti-Betula platyphylla Suk. mixed forest was the least, which was 14 t/hm2; (5) water holding capacity of soil in Quercus mongolica pure forest was strongest, which was 117.42 t/hm2, water holding capacity of soil in Betula platyphylla Suk.-Populus davidiana mixed forest came the next, which was 104.75 t/hm2, water holding capacity of soil in Betula platyphylla Suk. pure forest was the least, which was 37.80 t/hm2; (6) the soil initial infiltration rate was about 2.3~56.8 mm/min; The relationship between the infiltration rate and infiltration time could be fitted by power function, the correlation coefficient was greater than 0.95.
