| 摘 要： | 干热河谷是造林困难区域,过去造林遵循以树、草种的选择和造林时间、造林方法的选下来适应或逃避不利因素.但在经济条件制约下,采用现代育苗技术和造林方法受到限制,同时可选树、草资源十分有限,长期以来严重影响造林工作的进行和造林质量的提高.作者提出通过整地和防渗处理,人工引起并拦蓄地表径流,改善林木生长的上壤水分条件,以达到林木在干旱区域正常生长.

| Abstract: | The dry - heat valley is the hard region of afforestation. The use of modern seeding nursing technology and afforestation method are being limited by economic condition, the area and quality of affprestion is influenced. To develope runoff forestry, through soil preparation and soil permeate control, surface runoff is caused and stored by man, the soil water condition for forest growth is improved and forest growthes normally in dry - heat region. |
