摘要： 通过2013—2014年黄土沟壑区坡面的造林试验,对新型造林整地技术——大鱼鳞坑双苗造林技术(简称大鱼鳞坑)的林地土壤体积含水量、土壤侵蚀量和植被状况等进行研究,并与该地区如水平沟/传统鱼鳞坑等传统整地方式进行对比。结果表明:大鱼鳞坑的月平均土壤体积含水量分别比传统鱼鳞坑和水平沟整地高3.34%和1.95%;大鱼鳞坑的土壤侵蚀总量分别比传统鱼鳞坑和水平沟少1.11%和18.15%,差异显著(P<0.05);大鱼鳞坑整地乔灌木的平均株高比其他整地高(2014年末,乔木显著高于传统鱼鳞坑整地,灌木显著高于传统鱼鳞坑与水平沟整地)(P<0.05),且树木存活率分别比传统鱼鳞坑和水平沟整地高10.84%和8.34%、树木保存率分别高10.00%和8.33%。综合对比可见,大鱼鳞坑整地的林地土壤含水量较高,土壤侵蚀量较少;造林成活率较高,林分郁闭快。因此,大鱼鳞坑双苗造林技术适宜在黄土沟壑区的造林过程中应用和推广。

Abstract: The soil volumetric moisture content,soil erosion and vegetation growing status as well as the application of double-seedling afforestation technique in the big fish-scale pits were studied by two-year afforestation experiments on slopes in a loess gully region during the period from 2013 to 2014,and the two traditional soil preparation ways in the loess gully area were compared.The results showed that there were the discrepancies in the soil volumetric moisture content,soil erosion and vegetation growing status among different silvicultural techniques.The average monthly soil volumetric moisture content inside the big fish-scale pits were 3.34% and 1.95% higher than that in the traditional fish-scale pits and level trenches respectively,total soil erosion were 1.11% and 18.15% lower than that in the traditional fish-scale pits and level trenches respectively,and there was a significant discrepancy (P<0.05).Height of trees inside the big fish-scale pits was higher than that in the traditional fish-scale pits and level trenches.At the end of 2014,the height of arbors inside the big fish-scale pits was higher than that in the traditional fish-scale pits significantly,height of shrubs was significantly (P<0.05) higher than that in both traditional fish-scale pits and level trenches.Moreover,the survival rates of plants in the big fish-scale pits were 10.84% and 8.34% higher in 2013 and 10.00% and 8.33% higher in 2014 than those in the traditional fish-scale pits and level trenches respectively.The soil volumetric moisture content was the highest and the soil erosion was the lowest in the big fish-scale pits in the experimental area,and the closing of stand canopy was much sooner because of the highest survival rates of trees.In conclusion,the silvicultural technique in the big fish-scale pits is proper to be applied and popularized in afforestation in the loess gully region.
