中文摘要	[目的]探索北方退化干旱山地新栽幼树适宜的土壤保水措施,为北方干旱退化山地发展高效节水经济林产业提供科学依据。[方法]以2年生绿岭核桃嫁接幼树为试材,进行保水剂、秸秆覆盖和地膜覆盖等保水措施的不同组合处理,研究不同保水措施对土壤环境状况及新栽核桃幼树生长的影响,并采用主成分分析法对保水措施进行科学的综合评价。[结果]用土壤理化性质、土壤微生物数量和新栽幼树生长状况3个层次的17个指标构建了片麻岩山地新栽幼树保水措施的筛选模型,将原始数据标准化,提取出了4个主成分,可反映保水措施93.453%的综合效果。[结论]地膜覆盖是片麻岩山地新栽幼树最佳的保水措施。
英文摘要	[Objective]To find out suitable soil water conservation measures in arid and degradation mountain regions in North China,in order to provide scientific basis for the development of efficient water-saving forest industry in the northern arid degraded mountainous areas.[Methods]Two years oldLulinggrafted walnut seedlings were used as materials to study the effects of different combinations of aquasorb,straw and plastic film mulching on soil environment and growth of newly planted young walnut trees.Principal component analysis was used for the comprehensive evaluation of water conservation measures.[Results]Seventeen indices of physical and chemical properties of soil,soil microbial quantity and newly planted tree growth status were used to construct the screening model of water conservation measures on newly planted trees in gneiss mountains.Using the standardized data,four principal components were extracted from 17indices,which can explain 93.453% of the comprehensive effect of water conservation measures.[Conclusion]The plastic film mulching is the best water conservation measure for newly planted tree in gneiss mountains.
