摘　　要：文章通过对踏郎和黄柳植物沙障在内蒙古赤峰地区生长情况进行调查,分析了不同埋设深度的固定、流动两种沙地条件下植物沙障的生长状况,结果表明:固定沙地条件下,随着埋设深度的增加,植物沙障的成活率、高生长量和冠幅明显增加。埋设深度为60 cm、80 cm的黄柳成活率是埋设深度40 cm的8.4倍和12.6倍,当年高生长量分别为埋设深度40 cm的1.1倍和2.0倍,埋设深度为60 cm、80 cm踏郎成活率分别为埋设深度40 cm的2倍和2.1倍,不同埋设深度踏郎当年高生长量无显著差异。沙地条件(固定沙地和流动沙地边缘)对植物沙障的生长有显著影响。在流动沙地边缘生长的植物沙障树高和冠幅生长量显著高于固定沙地。黄柳生长对沙地条件较踏郎敏感,更易受其影响。踏郎对不同沙地条件的适应性较黄柳更强。In this study,plant sand block growth characteristics in different buried depths and in fixed sand and shifting sand were studied by surveying growth situation of Hedysarum fruticosum and Salix gordeivii in Chifeng,Inner Mongolia.The results indicated that:firstly,in fixed sand,survival rate,height increment and crown diameter of plant sand blocks increased with the buried depth increasing.For Salix gordeivii,survival rates in the buried depth60cm and80cm were8.4times and12.6times of that in the buried depth40cm,respectively;height increments in the buried depth60cm and80cm were1.1times and2.0times of that in the buried depth40cm,respectively.For Hedysarum fruticosum,survival rates in the buried depth60cm and80cm were2times and2.1times of that in the buried depth40cm,respectively;And height increments showed no significant difference among different buried depth.Secondly,sand land condition had mobvious influence on growth of plant block.Height and crown diameter increments of sand plant blocks in shifting sandwere obviously higher than that of in fixed sand.Thirdly,Salix gordeivii was more sensitive to sand condition than Hedysarum fruticosum.Hedysarum fruticosum was more adaptive to different sand condition than Hedysarum fruticosum.
