| 摘 要： | 2008年在科尔沁沙地的东南部，选择了具有代表性的4种不同土地利用方式，对其土壤水分变化进行了研究。结果表明：各种利用方式下，土壤水分在0 ~ 20 cm的表层稳定，在20 ~ 60 cm的中层变化剧烈，在60 ~ 100 cm的深层土壤水分稳定；各土地利用方式土壤含水量大小为大扁杏Prunus armeniaca × sibirica -花生Arachis hypogaea -玉米Zea mays＞大扁杏-麻黄草Ephedra sinica＞樟子松Pinus sylvestris var. mongolica纯林＞荒地（对照）；大扁杏-花生-玉米、大扁杏-麻黄草2种土地利用方式具有改良土壤水分，促进沙化土壤逆转的作用。不断地改进和推广此种优化的土地利用方式对于辽西北干旱地区经济发展及土壤改良都具有重要意义。图1表3参12 |

| Abstract: | In order to study soil-water dynamics laws with different tree and crop planting combinations on sandy lands in northwestern Liaoning Province, we surveyed four typical sandy lands from 0 100 cm depth at different usage modes. Results showed that： at these different modes, soil moisture is stable in 0 20 cm and 60 100 cm soil layer, soil moisture content changes violent in 20 60 cm soil layer; combinations of Prunus armeniaca × sibirica-Arachis hypogaea-Zea maysPrunus armeniaca × sibirica-Ephedra sinica Pinus sylvestris var. mongolica forestthe control（uncultivated land）, Prunus armeniaca × sibiricaArachis hypogaea-Zea mays and Prunus armeniaca × sibirica-Ephedra sinica could improve soil amelioration and soil-water conservation. Optimized land usage modes, which is of great significance to improving the economic development and soil amelioration of Liaoning Province in drought northwestern areas. |
