摘要

北极和亚北极地区的植被变化已被用作气候变化影响和严重程度的指标。本研究利用342幅MODIS NDVI影像，对2001-2018年冰岛植被的变率和长期变化进行了监测和评估。植被覆盖度变化趋势不显著(R = 0.16, p值= 0.05)，但NDVI低值区域(0.6，以森林为主)呈增加趋势。研究期内NDVI指数上升的面积约为3260 km2，下降的面积约为1635 km2。本研究的结果可用于组织应对气候变化和全球变暖的策略。

Remote sensing analysis to map inter-regional spatio-temporal variations of the vegetation in Iceland during 2001–2018

Changes in the vegetation of the Arctic and sub-Arctic regions have been used as indicators of the impact and seriousness of climate change. In this study, 342 MODIS NDVI images were used to monitor and assess the variability and long-term changes in the vegetation in Iceland in the period 2001–2018. An insignificant trend in the changes of the vegetation coverage (R = 0.16, p-value = 0.05) was obtained, however, it also resulted that the area with the low values of the NDVI (< 0.6) is decreasing, whereas the area with higher values of the NDVI (> 0.6, mostly forests) is increasing. The NDVI index during the study period rose for the area of about 3260 km2, while it declined for 1635 km2. The results of this study can be used for organizing the strategies preventing climate change and global warming.

期刊介绍： Acta geographica Slovenica publishes original research papers from all fields of geography and related disciplines, and provides a forum for discussing new aspects of theory, methods, issues, and research findings, especially in Central, Eastern and Southeastern Europe. The review accepts original research papers and review papers. Papers presenting new developments and innovative methods in geography are welcome. Submissions should address current research gaps and explore state-of-the-art issues. Research based on case studies should have the added value of transnational comparison and should be integrated into established or new theoretical and conceptual frameworks. The target readership is researchers, policymakers, students, and others who are studying or applying geography at various levels. Submissions are accepted in English or Slovenian.
