摘要 运用定位监测研究了雷竹林不同垦复方式(块状垦复、沿等高线带状垦复和全垦)下地表径流量和氮素养分流失状况。结果表明:垦复措施在一定程度上减少了地表径流,与未垦复林地相比,块状垦复减少幅度最大,平均减少23.49%;带状垦复次之,减少18.93%;全垦减少幅度7.52%。就土壤中全氮养分的维持而言,块垦效果优于带垦,带垦好于全垦;不同垦复方式对土壤中铵态氮含量的维持有一定差异,但差异未达到显著水平。不同垦复方式径流中的泥沙量由大到小的顺序为:全垦 > 未垦复(对照) > 带垦 > 块垦;块垦和带垦分别较全垦减少泥沙流失10.60%和8.02%,林地的水土保持效益十分明显。

Abstract:This project study on the surface runoff and nitrogen migration loss of the soil erosion characteristics in Phyllostachys praecox stands on slope-land with fixed monitoring in the different soil reclamation models, including over all tillage, belt tillage and patch tillage. The results showed that the reclamation can reduced surface runoff and produced different effects. There existed obviously reduces status that the patch tillage is the most reached 23.49% and the belt was 18.23% and all over in tillage processing was the worst only 7.52%. From the point of ability of maintenance the total nitrogen, the order of was patch tillage was better than that of belt tillage and all over in tillage model was the inferior. In the meantime, it showed that existed certain degree of difference for the soil nutrients of NH + 4-N but the difference was not significant. The order of soil sediment in surface runoff was follow:over all tillage > non reclamation (CK) > belt tillage > patch tillage; and will reduced the percentage of 10.60% in soil losing by patch tillage and the percentage of 8.02% comparison to all over in tillage, and came into being much more efficiency of water and soil conservation of experimental stands.
