摘要：林木高径比是基本测树因子之一。由于精确树高测定困难(特别是在结构复杂的森林中),对林木高径比的直接相关研究相对较少。文中从林木高径比的研究对象、影响因素、林木高径比与单一测树因子的关系、林木高径比模型模拟、林木高径比与林木遭受风雪灾害的关系5个方面进行综述,以期为进一步研究林木高径比奠定基础。目前大部分研究是针对结构简单、单层同龄的人工针叶纯林,针对分树种和分林层的研究极少且只有国外报道。林木高径比可能受到树龄、树种、竞争、立地和气候等多种因素的影响。胸径、断面积、材积和地径等单一测树因子与林木高径比关系较为紧密,且呈负相关,而树高、冠长、冠幅、树冠面积、冠径、树冠比和树冠闭合百分比等单一测树因子与林木高径比关系较不紧密。目前的林木高径比模型多以胸径为自变量,然后进行多模型优选,所选的最佳模型多为非线性模型;部分研究则在最佳模型中加入其他的自变量,如竞争、立地、林层和树种等因子。多数研究认为,林木高径比越大,林木越容易遭受风雪灾害。
The height to diameter ratio of forest trees is one of the basic factors in forest mensuration.Because of the difficulties in accurate tree height measurements,especially in forests with complex structure,there are relatively few studies of the height to diameter ratio directly.This paper reviews the research on height to diameter ratio in terms of research objects of and factors to height to diameter ratio,the relationship between the height to diameter ratio and single factor to tree measurement,the model simulation of the height to diameter ratio,and the relationship between the height to diameter ratio and trees suffering from wind and snow disasters,so as to lay a foundation for further research on the height to diameter ratio.Most researches presently focus on the pure coniferous plantation with simple structure,single layer and even age,while very few international studies are conducted in view of tree species and storey.Height to diameter ratio may be affected by many factors including age,species,competition,site and climate.The single factors to tree measurement such as DBH,basal area,volume and ground diameter are closely negatively correlated with the height to diameter ratio,while the factors such as tree height,crown length,crown width,crown area,crown diameter,crown ratio and crown closure percentage are loosely correlated with the height to diameter ratio.The height to diameter ratio models mostly take the DBH as the independent variable,and then optimum model is selected from multiple models.Most of the best selected models are nonlinear models.Some studies add other independent variables such as competition,site,storey,species in the best selected models.Most studies believe that the greater the height to diameter ratio,the more vulnerable trees are to wind and snow disasters.
