摘要
3PG森林生长模型是一个同时考虑天气、立地条件、经营措施和树木生理特性的光合生产力模型,在国外被广泛应用于林业研究和森林经营 运用3PG模型对我国广东省雷州半岛的3种桉树:尾叶桉、CloneU6和ABL12w5的生长规律进行研究并预测了6a的材积 研究结果表明:3PG模型是预测桉树人工林生产力的一种有效工具,其模拟精度和可靠性是令人满意的,它的应用为林业经营者制定合理的营林。
3PG forest growth model is increasingly widely used in a number of countries in the world for both research and management planning as a photosynthetic productivity model with combinations of climate, soil conditions, forest management and the physiology of species simultaneously. This model is applied to study the growth laws of the Eucalyptus plantations including E.Urophylla, CloneU6 and ABL12w5 and estimate their volumes in 6 years on the Leizhou Peninsula of Guangdong province in this paper. The results showed that 3PG model is a convenient and efficient means of predicting the productivity of Eucalyptus plantations with the satisfactory accuracy and reliability and can provide a successful and versatile basis for decisions on stand establishment, tending and harvesting for forest managers in relation to planting location, climate, soil conditions and forest management.
