摘要
[目的]研究杂交马褂木人工林在冲击沙壤土地区的生长规律和趋势。[方法]在标准地调查基础上,采用标准木解析法研究杂交马褂木人工林胸径、树高和材积生长规律,采用Logistic方程模拟生长并推测生长趋势。[结果]杂交马褂木生长迅速,6年生林分平均胸径、树高和材积分别为22.9 cm、20.6 m和0.206 6 m3;杂交马褂木生长具有阶段性,速生期为造林后4～8年,速生期生长量占总生长量60%以上。[结论]为杂交马褂人工林经营管理提供理论依据。
[Objective] The study aimed to explore the growing law and trends of Liriodendron Chinense× L.Tulipifera plantation on sandy loam.[Method] On the base of investigating sample area,we studied the growing law of DBH,tree height and volume of Liriodendron Chinense× L.Tulipifera plantation by analyzing sample trees,and speculated the growing trends by the use of Logistic equation.[Result] Liriodendron Chinense× L.Tulipifera plantation grows fast,with average DBH,tree height and volume grow up to 22.9 cm,20.6 m and 0.206 6 m3 respectively in 6 years old stand.The stage of growth is obvious;fast-growing period of stand is from 4 to 8 years after planting with more than 60% of mass growth.[Conclusion] All those provide theoretical foundation for the operating management of Liriodendron Chinense× L.Tulipifera plantation.
