提高半干旱山地水土保持效果的研究

半干旱山地水土流失严重，通过生物措施增加山地植被是治理山地水土流失的根本措施。半干旱山地造林成活率低的根本原因是缺水，提出了采取挖水平沟、鱼鳞坑、施用ABT生根粉等措施蓄水保墒，提高造林成活率，增强半干旱山地的水土保持效果。

Improving the Effect of Soil and Water Conservation in Semiarid Slopeland

There is severe soil and water loss in semiarid slopeland,the key measure to controlit is increasing the vegetation of slopeland by using biological measures. The major cause of lowpercentage of afforestation is shortage of water, so some measures are put out,such as digginghorizontal ditch,fish-scale pits,applying the ABT,to increase the ability of water conservationand preservation of soil moisture, to raise the percentage of afforestation and to improve thesoil and water conservation in semiarid slopeland.
