摘要

评估森林基金面临的经济压力是科学界面临的最大挑战之一,因为这一现象是动态的,而且很难在最佳时间获得相关数据。在这项研究中,我们希望分析、比较和汇总来自两个不同来源的两组后处理图像,如CORINE土地覆盖(具有互补数据集)和全球森林变化,以获得更准确和相关的结果。为此,我们对两个来源的后处理图像进行处理,然后通过保留Global Forest Change的临时分辨率和提取CORINE Land Cover的植被类型等质量信息,将两组数据的信息合并。对得到的数据集进行校正,然后进行处理。所获得的结果突出了每个数据源的局限性,全球森林变化的时间限制和缺乏关于森林类型的信息,以及在数据收集方面的方法差异和CORINE土地覆盖范围内较低的时间频率。因此,为了利用免费/可获得的联机数据来源获得关于欧洲联盟内某一区域林业动态的更精确结果,有必要合并这些数据集。

METHODOLOGICAL APPROACHES IN ASSESSING THE ECONOMIC PRESSURE ON FOREST RESOURCES. CASE STUDY: APUSENI MOUNTAINS
Assessing the economic pressure on the forest fund is one of the greatest challenges for the scientific world due to the dynamics of the phenomenon and the difficulties in obtaining relevant data and in an optimal time. For this study, we wanted to analyze, compare and aggregate two sets of post-processed images from two different sources, such as CORINE Land Cover (with complementary datasets) and Global Forest Change, to get a more accurate and relevant result. For this we processed the post-processed images from both sources, then merged the information of the two sets of data by keeping the temporary resolution from Global Forest Change and taking quality information like the type of vegetation from CORINE Land Cover. The data set obtained was corrected and then processed. The results obtained have highlighted the limitations of each data source, temporal limitation and lack of information on forest type in the case of Global Forest Change and the methodological differences in data collection and lower temporal frequency within the CORINE Land Cover. Thus, in order to obtain more precise results on the dynamics of forestry in a region within the European Union using free / available online data sources, it is necessary to merge such data sets.
