- Abstract:
- Using artificial simulated rainfall, the process of runoff and sediment yield was conducted in farmland, in returned farmland, in wondland of Lithocarpus dealbatus, Acacia dealbata, Pinus armandi in comtrast to the bareland. The results showed, the process of runoff and sediment yield were quadratic distribution in the six different forest floor. The sediment of the above-mentioned forest floor are successively bareland>farmland>returned farmland>Acacia dealbata>Lithocarpus dealbatus>Pinus yunnanensis. The litter are efficient in soil conservation. The bareland and farmland represent the main sourse of sediment yield, and returning of farmland to forest or grassland and building eco-forestry (grass) system is an effective measure for soil conservation and reducing sediment.
