摘要:
利用人工模拟降雨，以裸地为对照，对珠江上游耕地、退耕地、滇石栎、圣诞树、云南松五种地被进行产流产沙试验研究。结果表明，6种不同地被产流产沙过程都遵循二次函数方程分布，产沙量大小依次为裸地>耕地>退耕地>圣诞树>滇石栎>云南松。枯枝落叶层具有良好的土壤保持功能。裸地和耕地是该地区侵蚀产沙的主要来源，退耕还林还草、建立生态防护林体系是保持水土和减少泥沙的有效措施。
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.
