ABSTRACT

Factors relevant to degradation are important in every wood application. For wood used in ground and water contact; well documented abiotic factors (or agents) include exposure to temperature and moisture linked to the physiological requirements of biotic degradation agents such as wood-decaying fungi and bacteria. Other biotic degradation agents such as subterranean insects and marine borers occur overshadowing the effect of fungal and bacterial decay, but are restricted in geographical distribution and to aquatic applications, respectively. This review focusses on decay specific to soil exposure. The inherent material characteristics are important to durability in that heartwood and sapwood show differences in resistance to degradation between species, provenance, and individual trees. Wood durability testing methods and classification, as well as a summary of prominent models and variables suitable for regional-level modelling of in-ground wood durability are presented.

摘要

与降解相关的因素在每种木材应用中都很重要。用于地面和水接触的木材；有据可查的非生物因素（或试剂）包括暴露于与生物降解剂（如木材腐烂真菌和细菌）的生理需求相关的温度和湿度。其他生物降解剂如地下昆虫和海洋蛀虫的发生掩盖了真菌和细菌腐烂的影响，但分别在地理分布和水生应用方面受到限制。本综述侧重于土壤暴露特有的腐烂。固有的材料特性对耐久性很重要，因为心材和边材在物种、原产地和个体树木之间的抗退化性方面存在差异。木材耐久性测试方法和分类，
