摘　　要：通过对沙地刺榆生长状况进行调查,研究刺榆生物围栏的生长特性,结果表明:由15年生刺榆解析木生长资料分析可知,刺榆的速生期在5~13a,比较适合作为生物围栏的营建树种;对6年生刺榆生物围栏的生长分析可知,不同的立地条件和初植密度,刺榆围栏的生长差异显著,总体生长量由大到小为平缓沙地>缓起伏沙地>起伏沙地,营建密度1m×1m的刺榆围栏比1.5m×1.5m的提早郁闭,与初始速生期保持一致。Growth characteristics of Hemiptelea davidii in sandyland was investigated.Result shows that：from the growth data of 15-year-old Hemiptelea davidii we can see,fast-growing period of Hemiptelea davidii is from 5years to 13 years,it＇s suitable for plant fences to be tree species;from analysis of growth of biological fence for 6-year-old Hemiptelea davidii we can see,the growth difference of Hemiptelea davidii fence is significant under different site conditions and planting density.The descending order of the total growth is the flat sandylandslow fluctuation sandland undulating sandy land;planting density being 1m×1mclosed early than that being 1.5m×1.5m,which consistent with the fast-growing period.
