摘　　要：以圆柏6个品种(系)为试验材料,在干旱胁迫条件下对各品种(系)的生理生化指标进行测定与分析。结果表明,干旱胁迫对叶夹角、叶片水分饱和亏缺、细胞膜相对透性、叶绿素含量、游离脯氨酸含量、可溶性糖含量、过氧化物酶活性等指标均产生影响。方差分析可知,各品种(系)间有极显著差异。用模糊数学隶属度公式对各品种(系)的抗旱性进行综合评定,其抗旱能力从大到小依次为:‘兰塔桧’>京桧10-3>京桧6-2>京桧13-1>京桧22-1>‘金花桧’。Physiological indexes and biochemical indicators were tested and analyzed under drought stress with the six different varieties （lines） of Sabina chinensis（ L. ）. The result showed that the drought stress affected the leaf angle ,WSD,relative permeability of plasma menrbrane ,chlorophyll content,proline content, soluble sugar content and activity of peroxydase significantly. Vari- ance analysis indicated that extremely significant differences were exited in those indexes among the different varieties （lines） of S. chinensis （L.）. By the formula of vague mathematical jurisdiction, it was found that the ability of drought resistance on S. chinensis （L.） from high to low were S. chinensis ‘Lantagni＇ ,S. chinensis ‘ Jinggui 10-3＇ ,S. chinensis ‘ Jinggui 6-2＇ ,S. ehirtensis ‘ Jinggni 13-1 ＇ ,S. ehinensis‘ Jinggui 22-1＇ ,S. ehirtensis ‘ Jinhuagui＇.
