摘　　要：以13种高尔夫球场果岭配方土壤为材料,比较了一层结构、二层结构、三层结构等3种坪床结构对配方土壤水分特性的影响,用通径分析方法分析了各种配方成分对总含水量的效应。结果表明:全沙配方土壤总含水量及不同深度的体积含水量显著较少,泥炭、极细沙和粉粒粘粒含量越多,含水量越大。三种高尔夫球场果岭坪床结构中,一层结构的总含水量及不同深度的体积含水量显著较多。与三层结构相比,二层结构的总含水量及不同深度的体积含水量均较多,其中5个全沙配方土壤(A-E)及含泥炭较少的土壤(F)在二层结构中的总含水量及不同深度的体积含水量均显著较三层结构多,而其它含泥炭较多的7个配方土壤(G-M)在二层结构和三层结构中的总含水量及不同深度的体积含水量差异不显著。通径分析表明,中粗沙和泥炭是影响配方土壤总含水量的主要因子;细沙和极细沙及粉粒粘粒是影响配方土壤总含水量的次要因子。The impact of 3 kinds of golf green profile（1-layer,2-layer,and 3-layer） on the hydraulic properties of 13 rootzone mixtures was evaluated.The influences of rootzone component on total water content of mixtures were studied with path analysis method.The results were as follows.The mixtures with peat had much more total water content,and so had that with depth of rootzone compared to the pure sand mixtures.The more peat and sands with particle size 0.15 mm,the more water content had the mixtures.The mixtures had significantly much more water content with depth in 1-layer profile than that in other two profiles.There was significantly more water content in 2-layer profile for pure sand mixtures（A-E） and mixture（F）with low peat ratio than that in 3-layer profile,but there was no significantly more water content for 7 mixtures（G-M） with high peat ratio（〉5%） in 2-layer than that in 3-layer profiles.The path analysis indicated that the components of medium to coarse sand and peat were major factors that influencing the total water content,while the components of fine sand and sand with the particle size 〈0.15 mm had less influence on the total water content.
