中文摘要	2004年在甘肃高台县荒漠草原区按照不同密度(2 m2 m、2 m3 m、3 m3 m、3 m4 m)移栽花棒Hedysarum scoparium 200 hm~2,设定样方连续4年观测成活率、分枝数、高度、冠幅、生物量等的变化情况.结果表明,3 m3 m、3 m4 m为花棒的最佳移栽密度,在此密度下,花棒生长旺盛,枝条茂密,根系发育良好,丛间物种数增加,盖度提高,固沙效果明显.大于此密度,花棒植株低矮,生长缓慢,丛间原有物种消失,固沙效果较差.
英文摘要	200 hectares of transplanted Hedysarum scoparium were established with various density (2 m2 m, 2 m3 m, 3 m3 m and 3 m4 m) in the desert pasture of Gaotai County in Gansu during the year of 2004. The plots were set for 4-years continuous observation of the change conditions on survival rate, ramification number, height, canopy size and biomass. The result showed that 3 m3 m and 3 m4 m were the best density and under these densities, H. scoparium grew vigorously, ramified densely and developed good roots, plant species between the clumps of H. scoparium increased, and the coverage enlarged with an obvious sand-fixation effect. The density greater than 3 m3 m and 3 m4 m resulted in H. scoparium dwarfed and developed slowly; the original species between the clumps of H. scoparium disappeared with a poor sand-fixation effect.
