The research on the slat-tolerance index of main afforestation tree species in arid and semi-arid areas with secondary-salinization was carried out during the year 1991～1995,and the index of salt-tolerant were as follows: Populus enphratica Oliv.< g/L P. alba var pyramidalis Bge.< g/L Lyeium chinese Mill.< g/L Tamarix ramosissima Ledeb<0 g/L Hedysarum scoparium Fisch.et Mey.< g/L Hedysarum mongolicum Turcz.< g/L Elaeagnus angustifolia L.< g/L Hippophae rhamnoedes L.< g/L Haloxylon ammodendron(Mey).Bunge<0～50 g/L Pyrus betulaefolia Bge.< g/L Caragana intermedia Kuang et H.< g/L The ordination for capability of salt-tolerant species is from strong to weak: Haloxylon ammodendron,Tamarix ramosissma,Populus enphratica,Lyeium chinese,Caragana intermedia,Hedysarum mongolicum, Hippophae rhamnoides,Populus alba,Hedysarum scoparium,Elaeagnus angustifolia and Pyrus betulaefolia. 我国西北干旱地区次生盐碱地的主要造林树种的抗盐碱上限指标:新疆杨可以在土壤含盐量<g/L时生长正常;杜梨<g/L;柠条<g/L;花棒<g/L;沙棘<g/L;沙枣<g/L;枸杞<g/L;梭梭<0～50g/L;胡杨<g/L;柽柳<0g/L;杨柴<g/L.树种耐盐碱能力的顺序由大到小为:梭梭
