摘  要：
研究了红水河流域地区不同混交比例、不同造林时间的马尾松和红椎混交林的水土流失特征。结果表明:2005年营造的马尾松纯林的水土保持效益高于2012年营造的马尾松纯林,2005年营造的马尾松纯林的总产流量、总产沙量分别为2012年营造的马尾松纯林的84.54%、68.20%;混交比例为9∶1的马尾松红椎混交林具有较好的水土保持效益,总产流量为马尾松纯林的86.12%,总产沙量为马尾松纯林的86.79%;混交比例为6∶1的马尾松红椎混交林水土保持效益越来越好,产流量排序从2下降到5,产沙量排序从2下降到4。

摘  要：
The soil erosion characteristics of Pinus massoniana and Castanpsis hystrix mixed forest with different mixing ratio and different afforestation time in Hongshui River watershed were studied. The results showed that the soil and water conservation benefits of Pinus massoniana forest in 2005 were higher than those of Pinus massoniana forest in 2012. Compared with the total runoff and total sediment yield of Pinus massoniana forest in 2012,the total runoff and total sediment yield of Pinus massoniana forest in 2005 were 84. 54% and 68. 20% respectively. Pinus massoniana and Castanpsis hystrix mixed forest with a mixed ratio of 9∶ 1 had better soil and water conservation benefits. The total runoff was 86. 12% of the Pinus massoniana forest,and the total sediment yield was 86. 79%. The soil and water conservation benefits of Pinus massoniana and Castanpsis hystrix mixed forest with a mixed ratio of 6∶ 1 was better and better,and the order of runoff production dropped from second to fifth,and the order of sediment production dropped from second to fourth.
