摘　　要：以乌鲁木齐松树头煤矿为研究对象,采用无土基质配比方法,针对研究区土壤特点,选取选用粘合剂(A)、保水剂(B)、复合肥(C)和秸秆(D)为试验因素,进行无交互作用的正交试验,并对结果进行极差、方差分析影响。结果表明,粘合剂对植物高度、盖度均有显著影响,复合肥对植物盖度有极显著影响,同时也是生物量指标的主要影响因子。各因素主次顺序为C(复合肥)>B(保水剂)>A(粘合剂)>D(秸秆)。基质最优配比方案为A2B1C1D1,即当粘合剂用量为16 g/m2,保水剂为5 g/m2,复合肥为30 g/m2,秸秆为90g/m2时,可获得最佳的植被恢复效果。With Songshutou coal field in Urumqi as the study object, using soilless matrix ratio method, selecting bonding agent （A）, water retaining agent（B）, compound fertilizer（C） and straw （D） as test factors, orthogonal test without interaction was conducted, and the range and variance analysis were carried out based on the result. The results showed that bonding agent had significant effects on plant height and cover degree, while compound fertilizer had extremely significant effects on plant cover degree. The order of factors was C （ compound fertiliz- er） 〉 B （water retaining agent） 〉 A （bonding agent） 〉 D（straw）. The optimum matrix scheme was A2B^C~D1 , that is, the optimal vege- tation restoration effect can be obtained under the conditions of bonding agent 16 g/m2 , water retaining agent 5 g/m2 , compound fertilizer 30 g/m2, and straw 90 g/m2.
