This article starts a series of articles on dependences between the conditions of the growth of trees in forests and the technical aspects and directions of using the raw material obtained from these trees. This is a key feature for wood purchasers because it determines the efficiency of production and directly affects the final financial result of their activity. Wood represents an environmentally sustainable and renewable material, which is a widely available raw material on the market and must meet specific quality and strength requirements. These parameters indicate the utility values of wood and the possibilities of its use. One of the factors influencing the properties of wood is the type of the forest habitat it comes from. In order to determine this influence, tests were carried out to show how tree growth conditions affected changes in the density and strength of raw wood. The assumption (hypothesis) about the correlation between the static bending strength of Scots pine (Pinus sylvestris L.) wood and the forest habitat was verified on four forest types, i.e., fresh coniferous forest (FCF), fresh mixed coniferous forest (FMCF), fresh mixed forest (FMF) and fresh forest (FF). The properties depend largely on the wood structure, its origin on the cross section and the length of the stems. The raw material selected for the study came from Scots pine trees growing in forests in central Poland. The study confirmed the influence of the habitat on changes in the density and strength of pinewood. There was a correlation between the habitat FMCF and the quality parameters of the raw material, which reflected the wood structure r = 0.775; p < 0.05.

生境条件对松木特性的影响

本文开始了一系列关于森林中树木生长条件与使用从这些树木获得的原材料的技术方面和方向之间的依赖关系的文章。这是木材购买者的一个关键特征，因为它决定了生产效率并直接影响其活动的最终财务结果。木材是一种环境可持续和可再生的材料，是市场上广泛使用的原材料，必须满足特定的质量和强度要求。这些参数表明木材的实用价值及其使用的可能性。影响木材特性的因素之一是它来自森林栖息地的类型。为了确定这种影响，进行了测试以显示树木生长条件如何影响原木密度和强度的变化。关于苏格兰松静抗弯强度相关性的假设（假设）Pinus sylvestris L.) 木材和森林栖息地在四种森林类型上进行了验证，即新鲜针叶林 (FCF)、新鲜针叶林 (FMCF)、新鲜混交林 (FMF) 和新鲜林 (FF)。这些特性在很大程度上取决于木材结构、其横截面的起源和茎的长度。为研究选择的原材料来自生长在波兰中部森林中的苏格兰松树。研究证实了栖息地对松木密度和强度变化的影响。生境FMCF与原料质量参数之间存在相关性，反映木结构r=0.775；p < 0.05。
