摘要
森林因其丰富的生物多样性和维持生计的作用,在罗马尼亚的自然资产中名列前茅。在进入动荡的早期民主时代并面临许多社会经济调整的前社会主义国家,监测这一宝贵的生物群落对其可持续管理至关重要。本研究旨在利用GLAD实验室和全球森林观察提供的空间数据集,研究罗马尼亚摩尔达维亚县20年来(2001-2020年)的森林冠层损失情况。进行了基于地理信息系统的分析,以便计算森林冠层的损失及其在森林覆盖总量中所占的百分比,具体到五个相同持续时间的时间间隔。研究结果被放在与林业有关的主要法律框架和森林所有权变化的时间轴上,便于结合具体情况进行解释。研究区林冠损失在15270 ha (2001-2004) ~ 24000 ha(2005-2008)之间变化,在县域尺度上有不同的演变趋势。此外,在自然和行政因素的影响下,林冠损失值的高低呈西向东分布。这些发现增加了我们对后社会主义国家森林覆盖动态的理解,也突出了由政治和社会转型以及与国际环境治理一致引发的森林所有权和林业监管框架变化的影响。
FOREST CANOPY LOSS TRENDS (2001-2020) IN THE MOLDAVIAN COUNTIES OF ROMANIA. A GIS-BASED ANALYSIS
Forests rank at the top of the natural assets of Romania, both because of their rich biodiversity, and their livelihood-sustaining role. In the ex-socialist countries that entered the tumultuous early-democratic era and faced many socio-economic adjustments, the monitoring of this valuable biome becomes critical for its sustainable management. This study aims to examine 20 years (2001-2020) of forest canopy loss in the Moldavian counties in Romania, using the spatial dataset provided by the GLAD laboratory and the Global Forest Watch. A GIS-based analysis was performed in order to compute the forest canopy loss and the percentage of this loss in the total forest cover, specific to five time intervals of equal duration. The results are placed on the timeline of major forestry-related legal framework and forest ownership changes, facilitating a context-integrated interpretation. Forest canopy loss in the study area varies between more than 15,270 ha (2001-2004) to more than 24,000 ha (2005-2008), and different evolution trends can be identified at county scale. In addition, a West-East division of the high and low forest canopy loss values was identified, in correlation with natural and administrative factors. These findings add to our understanding of forest cover dynamics in post-socialist countries, also highlighting the influence of the changes in forest ownership and forestry regulation framework triggered by the political and social transition, and by the alignment to the international environmental governance.
