桂东南马尾松工程幼林生长量及其生物量节律研究

１９９１年～１９９６年，对桂东南马尾松工程幼林的生长量及生物量进行连续的定位定期观测。结果表明：马尾松工程林６年生幼林的林木蓄积量和生物量分别为３６．１６ｍ３／ｈｍ２和３６．８６ｔ／ｈｍ２，分别比常规造林１１年生和不施肥同龄林增加３倍～６倍；揭示了马尾松幼林生长量规律及其影响的主要气象因子，马尾松工程幼林各器官生物量随年龄的变化规律，并分别建立与地径逐月生长量的回归预测模型。

The Rhythm of Growth and Biomass of Engineering Young Forest of Pinus massoniana Lamb. in the Southeast Guangxi

The growth and biomass of engineering young forest of Pinus massoniana Lamb. in the southeast Guangxi was in situ observed for 6 years (1991~1996). The total growing-stock and biomass of 6 years old young forest of Pinus massoniana Lamb. was 36.16 m³/hm² and 36.86 t/hm² respectively, which were by 3~6 times higher than rule planting (11 years old) and no-fertilized young forest (the same years old). It brought to light the growth law of engineering young forest of Pinus massoniana Lamb. and its main influential meteorology factors, and to light the change law of organ biomass as tree ages on Pinus massoniana Lamb., and the predictional model of regression equation of organ biomass with ground diameter was built respectively.
