摘　　要：选择盐地碱蓬(Suaeda salsa)、中亚滨藜(Atriplex centralasiatica)、碱茅(星星草)(Puccinella tenuiflora)、西伯利亚白刺(Nitraria sibiric)、沙枣(Elaeagnus angusoliaif)五种耐重盐植物,分别在不同盐量的土壤上种植试验,种植前后测量土壤盐量、有机质、N、P、K等指标,统计伴生植被生长情况。结果表明,种植这些耐盐植物后,土壤盐量都有不同程度的下降,有机质、N、P、K水平都有不同程度的提高,伴生植被类型进一步丰富,并逐渐由盐生植物变成非盐生植物。Five species of high salt - tolerant halophytes, Suaeda salsa, Atriplex centralasiatica, Puccinella tenuiflora,Nitraria sibiric, and Elaeagnus angusoliaif are choosed. They are fested in the different soil. The guidelines before and after the planting , such as the salinity of the soil, Organic matter ,N,P, K, and so on, are determined, and the growing situation of the companied plants are also stnded. The results show that, after planting these salt - tolerant halophytes, the salinity of the soil decreases in different level. Organic matter, （ N, P,K） rise in some different level ,the types of companied plants become more and wore and qradnaly chonged from salt -tfolercnt to nomsalt- tfolerent holophgtes.
