以新疆甘家湖梭梭林自然保护区植被盖度C≥70％（ HC）、50％≤C＜70％（ MC）、30％≤C＜50％（ LC）和无林地（ NL）4种林地类型土壤为研究对象，分析测定了土壤养分和盐分在0～100 cm空间上的分布特征。结果显示：4种盖度林地土壤有机质质量分数均不高，仅有2．70～6．90 g· kg-1。土壤中全效氮、磷和速效氮、磷、钾质量分数与有机质质量分数呈极显著正相关（ P＜0．001），且全氮、全磷质量分数与有机质质量分数的比值相近（0．0330、0．0332）。 HC、MC、LC和NL林地土壤的速效磷和速效钾表聚现象明显，其中，土层深（H）0＜H≤20 cm中速效磷质量分数分别占其他土壤剖面的28．2％、40．5％、40．5％和33．2％，速效钾分别占41．8％、30．1％、34．2％和40．6％。4种类型梭梭林林地土壤剖面pH值均大于8．00，0＜H≤10 cm和60 cm＜H≤100 cm土层中总盐的质量分数较大。土壤中阴离子以Cl-和SO2-4为主，阳离子主要为Na＋和Ca2＋。综上所述，有林地土壤质量比裸地好，主要表现为有林地的有机质及速效养分质量分数较大，土壤盐度低。

With vegetation coverage C≥70%( HC) , 50%≤C<70%( MC) , 30%≤C<50%( LC) and non-wood land ( NL) in four types of woodland in Xinjiang Ganjiahu Haloxylon Nature Reserve, we measured and analyzed the spatial distribu-tion characteristics of soil nutrients and soil salinity from 0 to 100 cm.The organic matter contents of four woodlands were all not high, with 2.70-6.90 g· kg-1 .The correlation between the contents of total nitrogen, phosphorus and available ni-trogen, phosphorus, potassium with organic matter in soil was positive significant ( P<0.001) , and the ratios of total phos-phorus and nitrogen with organic matter were similar (0 .033 0, 0.033 2) .Available phosphorus and available potassium were obvious in the soil surface, and the soil available phosphorus content in 0<H≤20 cm soil layer of HC, MC, LC and NL accounted for 28.2%, 40.5%, 40.5%and 28.2%respectively, and available potassium content accounted for 41.8%, 30.1%, 34.2%and 40.6%, respectively.pH value of soil profile in four Haloxylon woodlands was greater than 8, and total salt content in0<H ≤10 cm and 60 cm<H≤100 cm soil layers were higher than that in 20 cm<H≤60 cm middle layer.Cl-and SO2-4 were the main anions, and Na+and Ca2+were the main cations in the soil.Therefore, the soil quality of woodland with higher organic matter and available nutrient content of woodland, but with lower soil salinity, was better than that of non-wood land.
