摘要

本研究旨在利用Sentinel-2A图像数据调查森林覆盖的变化。采用基于归一化植被指数(NDVI)产品的图像差异变化检测方法,对2016年至2017年祖宾波托克市(科索沃)毁林、非森林和森林面积的年度结果进行了分析。研究表明,由于人类活动(砍伐和焚烧森林),该市的森林覆盖率发生了变化。利用Sentinel 2A波段组合和谷歌地球(GE)提供的高分辨率(VHR)图像证明了变化的足迹。从24873.61公顷的整体森林覆盖面积来看,年内检测到的变化如下:24423.57公顷(98.19%)被映射为森林,113.75公顷(0.46%)被映射为非森林,336.77公顷(1.35%)被映射为森林。这些结果可用于查明人为砍伐森林的情况,并为今后几年制定监测森林的计划。

Mapping Forest Cover Changes using Sentinel-2A Imagery in the Municipality of Zubin Potok, Republic of Kosovo
This research aimed to investigate the changes in forest cover, utilizing Sentinel-2A imagery data. Annual results of deforestation, non-forest, and forest area in the Municipality of Zubin Potok (Kosovo) between 2016 and 2017 were presented and analyzed by applying the image difference change detection method on a Normalized Difference Vegetation Index (NDVI) product derived for both years. The study reveals that forest coverage in this municipality has changed due to human activity (harvested and burnt forests). The footprint of changes was evidenced by using Sentinel 2A band combinations and very high resolution (VHR) images available in Google Earth (GE). From the overall forest-covered area of 24,873.61 hectares, the detected changes during the annual period are as follows: 24,423.57 ha or 98.19 % is mapped as forest, 113.75 hectares or 0.46 % as non-forest, and 336.77 or 1.35 % of the area forest is mapped as deforestation. These results can be used to identify human-made deforestation and to develop monitoring forest plans for the coming years.
