干曲线模型是树木材种出材量与出材率估算及经济效益评估的科学依据。介绍了干曲线模型的分类及其国内外研制现状,重点从干形指标、干曲线模型与林分经营间作用关系的角度,深入阐述了响应林分经营因子的干曲线模型研制的理论基础及技术进展,分析指出了树木干形模拟技术存在的问题,以期为今后树木干形的科学模拟提供参考。
The dry curve model is the scientific basis for the estimation of timber output and yield and the evaluation of economic benefits of tree species. This paper introduces the classification of dry curve models and the status quo at home and abroad. From the point of view of the relationship between dry index, dry curve model and stand management, this paper elaborates the theoretical basis for the development of dry curve model in response to stand management factors and The progress of the technology was pointed out. The problems existing in the simulation technology of dry wood were pointed out, which could provide a reference for the future scientific simulation of wood dryness.
