摘  要：
为了在内蒙古赤峰市选定适宜的沙障类型,选用黄柳、踏郎设置沙障,利用5 a连续观测数据,对比分析了黄柳、黄柳-踏郎、踏郎3种植物沙障植被覆盖度、沙丘移动距离、投入与产出比例。结果表明,黄柳、黄柳-踏郎、踏郎3种植物沙障设置后第5年平均植被盖度分别为44.9%、80.7%、79.7%。3种植物沙障设置后3 a间,仅第1年沙丘移动0.50~0.54 m,自第2年起沙丘基本被固定,3种植物沙障沙丘移动距离分别为0.54、0.51、0.50 m。3种植物沙障设置时种条用量不同,分别为7 000、6 400、6 000 kg·hm~(-2)。3种植物沙障种子(除黄柳外)和种条产量较高,5 a后种子和种条总产量分别为0、174.5、203.3 kg·hm~(-2),62 350、62 870、62 650 kg·hm~(-2)。随着治理时间推移,3种植物沙障投入与产出比逐年减小,自第3年起产出均高于投入。3种植物沙障投入与5 a总产出比为0.20、0.15、0.14,投入与5 a平均产出比为1.02、0.76、0.71。从植被恢复速度、投入成本、种子和种条产量、投入与产出比等方面综合分析,踏郎沙障最好、黄柳-踏郎沙障次之、黄柳沙障最差。

摘  要：
In order to select the right sand hedge in Chifeng,Inner Mongolia,Salix gordejevii Y. L. Chang and Hedysarum fruticosum var. mongolicum( Turcz.) were established in sand hedges of S. gordejevii,Salix-Hedysarum and H. fruticosum var.mongolicum,performances on vegetation coverage,sand dune shift distance,input-output ratio were monitored for 5 a. The results showed that average vegetation coverages for S. gordejevii sand hedges,Salix-Hedysarum sand hedges and H. fruticosum var.mongolicum sand hedges were 44.9%,80.7%,79.7% in the 5th year. Within 3 a after establishment,sand dunes were basically fixed since the 2nd year except for shifts of 0. 54,0. 51,0. 50 m in the 1st year for 3 hedges,respectively. Cuttings for 3 hedge establishments were 7 000,6 400,6 000 kg·hm~(-2),respectively. Yields of seeds( except S. gordejevii) and cuttings were satisfactory,with overall yield of seeds and cuttings being 0,174.5,203.3 kg·hm~(-2),62 350,62 870,62 650 kg·hm~(-2)in the 5th year. Input-output ratio decreased with time,and the outputs exceeded the inputs since the 3rd year. Ratios of input to overall outputs for 5 a and the ratio of input to average output for 5 a were 0.20,0.15,0.14,1.02,0.76,0.71 respectively. To summarize,H. fruticosum var. mongolicum is the optimum species for sand hedge,followed by Salix-Hedysarum and S. gordejevii sand hedges in a descending order.
