中文摘要	采用系统抽样的方法,对兰州南北两山砾质红砂土和灰钙土喷播种植的油蒿进行了统计分析评价.结果显示:油蒿表现出对兰州南北两山瘠薄土壤非宜林地的广泛适应性.砾质红砂土生长3a生油蒿,水平沟内,油蒿地茎以5~10mm为主,高度以100~160cm为主,平均盖度达到90%以上,密度达到17株?m~(-2);人工整地形成的60°以上斜坡,油蒿地茎以0~5mm为主,高度以80~100cm为主,平均盖度达到80%,密度达到30株?m~(-2);坡度大于60°天然陡坡面,油蒿地茎以0~5mm为主,高度以20~40cm为主,平均盖度达到20%,密度达到25株?m~(-2);45°塌陷缓坡虚方区域,油蒿地茎以5~10mm为主,高度以60~80cm为主,平均盖度达到60%,密度达到43株?m~(-2).灰钙土60°人工陡削坡面5a生油蒿:油蒿地茎从上坡到下坡,上坡位地茎小于4mm,下坡位地茎接近25mm,坡面以地茎4~9mm为主,高度以40~80cm为主.油蒿盖度上坡位达到40%,密度达到16株?m~(-2);下坡位,油蒿盖度达到48%,密度达到12株?m~(-2).油蒿在兰州南北两山绿化中,随土壤水分,植物盖度和密度的关系表现为:大的覆盖度以个体大冠幅,总体密度小为特征;小的覆盖度以个体小冠幅,总体密度大为特征.
英文摘要	In this article,systematic sampling methods are used to analyze the growth condition of Artemisia ordosica cultivated in red sand soil and the sierozem in Lanzhou North-South Hills.It is found that A.ordosica has an extensive adaptability to the barren and non-suitable for afforestation soil in Lanzhou North-South hills:The A.ordosica with three-year growth period is able to cultivate in the red sandy soil.In the horizontal ditch, A.ordosicastalk mainly reaches 5~10mm,with height of 100-160cm,average coverage of more than 90%,and density of 17trees per square meter; In the artificial slope over 60°,A.ordosica stalk mainly reaches 0~5mm,with height of 80~ 100cm,average coverage of 80%,and density of 30trees per square meter;In the original slope over 60°,A.ordosica stalk mainly reaches 0~5 mm,with height of 20~40cm,average coverage of 80% ,and density of 25trees per square meter; In the untamped backfill terrace with collapse and slope of 45°,A.ordosicastalk mainly reaches 5~ 10mm,with height of 60~80cm,average coverage of 60%,and density of 43trees per square meter; The A.ordosica with five-year growth period is able to cultivate in the artificial sierozem slopes of 60°.Its stalk is 4mm in the uphill and 25mm in the downhill and mostly in the slope surface reaches 4~9mm.The A.ordosicaheight mostly reaches 40~80cm,with average coverage of 40%and density of 16trees per square meter in the uphill, but with average coverage of 48% and density of 12 trees per square meter in the downhill.The A. ordosica in the afforestation of Lanzhou North-South Hills has the characteristics that large coverage with big crown and small bulk density,but low coverage with little crown and large bulk density, dependent on soil moisture.
