摘　　要：以A(耐盐树木)、B(边缘材料)、C(衬底材料)和D(沸石用量)的植穴结构控制因素为自变量,采用同步法测取定植穴控制体内外Na+量变化的相对序时降低值为因变量,开展L9(34)正交试验,利用植穴结构控制体(PHCC)提高盐渍土区造林成效的方法,以获取各因素与水平对穴内Na+含量的控制力与作用信息及最佳组装参数,为逆境生态重建的生态设计与技术组装提供服务。结果表明,控制力大小的因素排序为B>C>A>D;其最佳组合为A3B3C1D1,即选用绒毛白蜡、反渗透膜、草炭和沸石100g组合作为植穴结构参数,可使穴内Na+含量比穴外减少88.20%~90.48%,其置信区间的可靠性为95%。By establishing the Planting Hole Composition Control system （PHCC） of artificially reforestation saline soil, four internal factors of PHCC, namely A （salt-tolerant plants）, B （edge material）, C （substrate material） and D （ content of Na^＋ d dosage of zeolite）, were selected as independent variable, ecrement synchronously as the dependent variable. In order to and measured internal and external providing services for ecological design on adversity ecological reconstruction and assembled technology, orthogonal experiment L9 （3^4） was designed for understanding the controlling power and the role of various factors and levels on internal content of Na^＋, and identifying the optimum assembled parameters. The results showed that the order of control power was B〉C〉A〉D, the best combination was A3B3C1D1, namely the combination of Fraxinus tomentosa, reverse osmosis membrane, peat and zeolite with 100 g. Under this combination, the planting hole internal contents of Na^＋ reduced 88. 20 % - 90. 48 % compared with the external contents, and its confidence interval was 95%.
