| 摘 要： | 辽西地区属于半干旱季风气候区,年平均温度为7.1—8.2℃,年降水量为400—600mm,年蒸发量为1600mm,为降水量的3—4倍。干燥是该区总的气候特点。该区的植物群落主要为旱生的森林灌丛或草本植物群落,针叶树建群种为油松,阔叶树为蒙古栎,元宝槭,黄榆;灌木主要为荆条和酸枣。土壤是在各种岩石风化物残积母质上,以及黄土、红土母质上发育的淋溶褐土和褐色性土,土壤干旱瘠薄。水分是这一地区限制造林树种成活及生长的主要因子,本文试图通过对树种抗旱性的测定和分析,确定树种的抗旱能力,从而为辽西地区的造林提供树种选择的依据。

| Abstract: | The drought resistance of several silvicultural species have been determined and analysed in the aspects of growth, physiology and anatomy, passed a judgment on their drought resistance by using complex indexes. The results indicate that Arborvitae and Chinese pine are the best drought resistance among the tree species, Mongolian Oak and parple blow maple are the second one, Black locust is poor in comparison with other tree species. In shrub species, common smoketree, common seabuckthorn and little leaf peashrub are relatively drought-resistant, while shrubby labseindigo is rather poor resistant to drought. |
