摘　　要：利用辽宁西北部沙漠化地区雨季湿度大、蒸发量小的特点,采用一年生差巴嘎蒿枝条生物网方格进行了3年的固沙试验研究。试验研究表明:人工移栽的差巴嘎蒿的成活率明显高于机械移栽的成活率。两种处理所在的沙丘上的流沙第二年得到了有效的控制,植被恢复的速度明显高于对照。深入研究了差巴嘎蒿生物网方格固沙的方法,分析了生物网方格固沙的原理,为辽西北沙漠化地区流动沙丘的治理与生态修复提供了新的理论依据与技术支持。Three-year experiments of fixing sand by using biological net of one-year-growth Artemisia were conducted in desert area of Liaoning Northwest, where humidity is high and evaporation is low in rainy season. Results show Arternisia＇s survival rate of manual plant were higher than machine plant and the speed of vegetation restoration in two experimental areas were quicker than CK. Also, moving sand was controlled validly in the second year in two experimental areas. The authors investigated thoroughly the fixed-sand method of biological net of Artemisia and analyzed fixed-sand principle of it and aimed at providing theoretical basis and technological support for moving-sand harnessing and ecological restoration in desert area of Liaoning Northwest.
