摘　　要：在建水县石质山地进行了墨西哥柏＋车桑子混交模式和干香柏＋车桑子混交模式的造林试验。6年的试验结果表明：两种乔灌混交模式的造林成活率、保存率均较高，林木的生长状况也较好。前者中墨西哥柏的造林成活率和保存率均为100％，车桑子均为94．44％；后者中干香柏的造林成活率为77．78％、保存率为72．22％，车桑子均为100％。经用层次分析法对两种混交模式的乔灌木层次的明显性、群落的盖度、林木的高生长和径生长等4个方面作比较，得出墨西哥柏＋车桑子混交模式的稳定性优于干香柏＋车桑子混交模式。由于石质山地的土壤较为瘠薄，影响了乔木树种的生长，使两种乔灌混交林中乔木树种墨西哥柏和干香柏的生长高峰期提前在第3-4年到来。相比较墨西哥柏比干香柏更能适应试验区恶劣的自然条件，其造林后第6年树高和地径生长量仍达0．99m和1．08cm，而干香柏只有0．44m和0．46cm。Afforestation experiment of Cuppressus lusitanica mixed with Dodonaea viscosa and Cupressus duclouxiana mixed with Dodonaea viscosa were conducted. The and preservation rate of these two patterns were all good vival rate and preservation rate of Cuppressus lusitanica resuhs of six years experiment showed that the survival rate , and the growth of trees were promising as well. The surand Dodonaea viscosa in the first pattern were 100 % and 94.44 % respectively, while the survival rate and preservation rate of Cupressus duclouxiana in the second pattern were 77.78 % and 72.22 %, and that of Dodonaea viscosa were all 100 %. Adopting the analytic hierarchy process, two mixed planting patterns were compared from the layers vegetation, coverage, height growth and diameter growth. The results of comparison indicated that the stability of Cuppressus lusitanica mixed with Dodonaea viscosa was higher than that of Cupressus duclouxiana mixed with Dodonaea viscosa. The soil of karst rocky mountain was infertile, which affected the growth of tree species, made the growth peak time of two Cuppressus changed from the sixth year to the third or fourth year. The adaptability of Cuppresstts lusitanica to harsh environment was higher than Cupressus duclouxiana, the growth increment of tree height and DBH of the sixth years were 0. 99 m and 1.08 cm, while that of Cupressus duclouxiana were 0. 44 m and 0. 46 cm.
