The effects of restoration patterns on soil aggregates and aggregate-associated soil water soluble Na+, K+, Ca2+, Mg2+ in abandoned salinized farmland were studied in the experimental field on the alluvial fan oasis of Manas River Basin.The results indicated that different restoration patterns in abandoned salinized fields significantly reduced the soil pH value and EC(p < 0.05), the scales of pH value under monoculture, intercropping and crop rotation were 10.7%,9.7%,10.6% lower than that under abandoned salinized field, respectively, the values of EC under monoculture, intercropping and crop rotation were 19.2%,71.0%,84.1% lower than that under the abandoned salinized field, respectively; the different reclamation modes increased the contents of > 0.25 mm soil macroaggregate (p < 0.05), the contents of > 0.25 mm soil macroaggregate under the monoculture, intercropping and crop rotation were 15.8%,13.2% and 15.6% higher than that under abandoned salinized field, respectively, and significantly higher than the other two sizes of aggregates (p < 0.05), the aggregate structure of the soil was significantly improved; water soluble cation contents of different restoration patterns were the highest in the size of < 0.25 mm aggregate, and content of cation decreased in the order: Ca2+ > Mg2+ > Na+ > K+. Intercropping and rotation significantly reduced water soluble cation contents (p < 0.05),which implied that soil improvement effect under intercropping and rotation was significant. The intercropping and rotation are the preferred modes of vegetation restoration in saline soil.
