摘　　要：试验对13种高尔夫球场果岭配方土壤的饱和导水率进行了测定,建立了配方土壤饱和导水率与配方基质之间显著相关的回归模型,并对模型实施了因子效应分析和模拟优化分析。结果表明,不同配方土壤的饱和导水率差异很大。配方土壤的饱和导水率随中粗沙与细沙含量的增加而增大,随泥炭含量的增加而减小。当极细沙＋粉粒＋黏粒含量取中低水平时,饱和导水率随极细沙＋粉粒＋黏粒含量的增加而增大,而取中高水平时,饱和导水率则随极细沙＋粉粒＋黏粒含量的增加而减小。按美国高尔夫协会推荐的饱和导水率大于15 cm/h的要求,试验得到的优化配方方案为中粗沙含量70.6%~74.1%、细沙含量18.5%~20.3%、极细沙＋粉粒＋黏粒含量7.1%~8.6%、泥炭含量0~0.9%。The saturated hydraulic conductivity（Ksat） of root zone formula soil in 13 golf course green was tested;and a significantly correlative regression model between Ksat and formula components of formula soil was established.Factor analysis and simulation optimization of the model were conducted.The results showed that Ksat of the formula soil increased with the increase of content of middle-coarse and fine sand,while decreased with the increase of peat content.Ksat increased with the increase of content of very fine sand＋ silt＋ clay when it was at low to middle level,but decreased when it was at middle to high level.As it was recommended by USGA（United States Golf Association）（Ksat 15 cm / h）,the optimal soil mixture was middle-coarse 70.6%~74.1%,fine sand 18.5%~20.3%,very fine sand＋ silt＋ clay 7.1%~8.6%,and peat 0%~0.9%.
