Effects of Ecological Tending on the Litter and Soil Hydrological in Young Stand of North-China Larch
Ecological tending is the foundation and key technology of forest conservation, also an important component of forest ecosystem management. This paper compares the effects of ecological tending on the litter and soil hydrology in young stand of north-China larch. The results show that: Ecological tending change the environmental conditions of light and temperature, which is beneficial to the decomposition of litter, total reserves of litter reduce by 41 %. The natural water-holding,maximum water-holding capacity, effective water-holding capacity and actual water-storing capacity of litter decreased significantly. Tending changed the structure of surface soil, thereby reducing the soil bulk density, improved the capillary porosity and total porosity, the ventilation performance and the water holding capacity of the soil. Tending increased the steady infiltration rates(0.33 mm/min) and water infiltration capacity of soil, which is beneficial to decrease or containment of soil erosion.
