摘　　要：对贵州省和福建省4年生南酸枣幼树在不同立地条件下的生长情况进行统计分析,结果显示:在海拔1 250 m以下,海拔和母岩不是南酸枣用材林培育的限制因子,影响南酸枣生长的主要立地因子是小地形和土层厚度,营造南酸枣用材林应选择土层深厚(60 cm)、疏松肥沃的山体中下部、沟谷、低洼地背风地段。Statistical analysis was conducted to the status of 4 years old Choerospondias axillars growth under different site conditions in Guizhou and Fujian provinces. The results indicated that below altitude of 1 250 m, altitude and parent rock are not the limiting factor for timber forest cultivation of Choerospondias axillars. The main site factors to impact growth of Choerospondias axillars are microtopography and depth of soil layer. The site conditions selection for timber forest cultivation of Choerospondias axillars are as follows： deep soil layers （60 cm）, mid-lower part, valley and leeward sites of low-lying land of mountain with loose fertile soil.
