This paper describes a permanent research platform (PRP) designed and implemented in “Codrul secular Slătioara” and its surroundings (2,205.85 ha), having also the role of introductory paper for future research articles based on data collected from this platform. “Codrul secular Slătioara” is known as one of the largest temperate mountainous intact forests of Europe and, in 2017, it was included in UNESCO World Heritage List, as part of the “Ancient and Primeval Beech Forests of the Carpathians and Other Regions of Europe”. Moreover, the PRP overlaps other three scientific reserves, the share of strictly protected forests exceeding 70%. This platform has a multiple role, being developed for research, conservation and educational activities. The PRP was designed for an ecological analysis of the intact forest ecosystems. It contains 193 circular sample plots, each of them of 500 m², and it is structured on two levels. The first level contains 58 sample plots corresponding to a square grid of 500 × 500 m, stretching over the entire forested area, and the second level contains 135 plots, placed according to a square grid of 100 × 100 m, covering 136 ha within the core area of the UNESCO site. We measured the characteristics of 8296 living trees, 1743 standing dead trees, 1900 dead wood trunks, 3214 saplings, and the abundance–dominance indices of flora species. Thus, we identified 14 tree species, 17 shrub species, and 248 other cormophyte species forming the herbaceous layer. In terms of volume, the main tree species are Norway spruce, silver fir and European beech. The tallest species are Norway spruce (56 m) and silver fir (51 m). The average volume of living trees is 659 m³·ha⁻¹, with a maximum of 1441 m³·ha⁻¹. The mean total dead wood volume is about 158 m³·ha⁻¹, with sample plots where the total dead wood volume exceeds 600 m³·ha⁻¹. After presenting the results of preliminary data processing, the paper describes the main research topics to be further considered, based on the PRP, and the foresights related to the PRP’s monitoring and development.

罗马尼亚Slătioara遗址及其周围地区完整的温带山区森林生态研究的常设研究平台

本文介绍了在“ Codrul secularSlătioara”及其周围地区（2,205.85公顷）中设计和实施的永久性研究平台（PRP），并基于从该平台收集的数据，为以后的研究文章提供介绍性论文。“ Codrul世俗Slătioara”被称为欧洲最大的温带山区原始森林之一，并于2017年被联合国教科文组织列入世界遗产名录，并成为“喀尔巴阡山脉和欧洲其他地区的古老和原始山毛榉森林”的一部分”。此外，PRP与其他三个科学保护区重叠，严格保护的森林所占份额超过70％。该平台具有多种作用，正在开发用于研究，保护和教育活动。PRP旨在对完整森林生态系统进行生态分析。²，它分为两个层次。第一层包含58个样地，对应于500×500 m的正方形网格，覆盖整个森林区域，第二层包含135个样地，按照100×100 m的正方形网格放置，覆盖了136公顷。教科文组织网站的核心区域。我们测量了8296棵活树，1743棵死树，1900棵枯木树干，3214棵树苗以及植物群的丰度—优势指数的特征。因此，我们确定了形成草本层的14种树种，17种灌木种和248种其他轻生植物。就数量而言，主要树种为挪威云杉，银杉和欧洲山毛榉。最高的树种是挪威云杉（56 m）和银杉（51 m）。活树平均体积为659 m ³·ha ^-1，最大为1441 m ³ ·ha ^-1。平均死木总量约为158 m ³ ·ha ^-1，其中样地的总死木体积超过600 m ³ ·ha ^-1。在介绍了初步数据处理的结果之后，本文介绍了基于PRP的需要进一步考虑的主要研究主题以及与PRP的监视和开发有关的远见。
