摘　　要：通过对盐碱地适宜经济树种的筛选,按照自然环境中树种与草种搭配、树种与树种搭配等盐碱地治理模式,并以造林成活率、经济效益、治理前后土壤有效成分等为主要指标开展了对比试验,选出经济效益好、治理效果明显的优良经济树种,结果表明:西伯利亚白刺、宁杞一号、大麻叶及内蒙古种源沙枣等耐盐碱树种,从存活率方面看,枸杞新品种对于中度盐碱地治理表现最好;西伯利亚白刺羊草复合模式对于重度盐碱地治理表现较好;内蒙古种源沙枣模式对于轻度盐碱地治理表现中等。从经济效益方面看,枸杞模式最好;改良土壤方面看,西伯利亚白刺模式最好。Through screening for economic species in saline-alkali soil, according to the alkali control modes （tree species and grass seed , and tree species with tree species） in natural environment, comparative experiments were conducted by taking survival rate of afforestation, economic benefit, active ingredients of soil before and after combating as primary indicators. Superior economic species with optimal economic benefit and significant control effect were selected. Result shows that among salt-tolerant tree species ： Nitraria sibirica, Lycium barbarum ＇ Ningqi Yihao＇ ,Cannabis sativa ,Elaeagnus angustifolia （Inner Mongolia provenance ）, from the aspect of survival rate, control modes of new varieties of Lycium chincnse in the moderate saline-alkali land is the optimal; compound modes of Nitraria sibirica and Leymus chinensis is better;the control mode of E1aeagnus angustifolia （Inner Mongolia Provenance）＋mild saline-alkali land performed moderate. From the economic benefit, Lycium chinense mode is the optimal;from the aspect of the soil, Nitraria sibirica mode is the optimal.
