摘  要：
在干旱荒漠区引种了6种4年生云杉属植物,通过3a的抗寒性、抗旱性、耐盐碱性、抗病虫性观测,建立生长适应性评价体系,并对几种云杉生态适应性进行综合排序。结果表明,蓝云杉保存率最高,白杄、白云杉次之,红皮云杉、欧洲云杉较差;蓝云杉、白云杉和白杄的平均高生长量、地径生长量大于川西云杉、红皮云杉和欧洲云杉。欧洲云杉和红皮云杉抗旱性较差,其余均具有较强的抗旱性。欧洲云杉抗寒性最差,其次为红皮云杉,其余种抗寒性相对较强。通过各项指标打分及综合分析认为蓝云杉、白杄适应性较强,可作为干旱荒漠区理想的造林树种。

摘  要：
Four-year-old seedlings of several Picea species were introduced in arid desert area.Three-year observations were carried out from the aspects of cold,drought,salt,disease,and pest resistances.An evaluation index system was established with key factors.Ecological adaptabilities of several Piceaspecies were comprehensively sequenced.The results showed that the survival rate of the seedlings of P.pungens‘Glauca Globosa'was the highest,P.meyeri and P.glaucaranked in the second place,and P.koraiensis and P.abies were the lowest.The average height increment and base diameter increment of P.pungens ‘Glauca Globosa',P.glauca,and P.meyeri were more than P.likiangensis,P.abies and P.koraiensis.The drought resistance of P.abies and P.koraiensis was poor,and others had strong drought resistance.The cold resistance of P.abies was the worst,followed by P.koraiensis,and the others demonstrated strong cold resistance.P.pungens ‘Glauca Globosa'and P.meyeri which could be used as ideal afforestation species had good adaptability through all indexes score and comprehensive analysis.
