摘要

干旱是当今世界面临的影响社会和环境的重大极端事件之一。多布罗赫亚地区位于罗马尼亚东南部,气候温和,受大陆影响强烈,经常受到干旱的影响,给广大农业区造成重大损失和经济损失。通过将卫星产品(网格数据)的植被指数和生物物理参数与现场数据(点数据)相结合,有助于降低风险、持续监测植被和实施管理。基于干旱指数(NDDI)和光合有效辐射吸收分数(FAPAR)对罗马尼亚Dobrogea干旱程度和强度进行了评价;ii)火灾分析,基于热异常/火灾地点产品(MCD14DL);iii)火灾与NDDI的相关性;iv)以及火灾与地表温度(LST)产品之间的相关性。2000-2015年3月22日- 8月29日期间,利用MODIS(中分辨率成像光谱仪)每日和8 d合成产品计算植被指数、生物物理参数和火灾。研究结果突出了多布罗吉亚地区受干旱(中度、重度和极端)和火灾影响最严重的地区。

Evaluation of Droughts and Fires in the Dobrogea Region, Using Modis Satellite Data
Abstract Drought is one of the most significant extreme event facing the world, affecting the society and the environment. Located in SE Romania, Dobrogea Region is characterized by a temperate climate with strong continental influences, being affected by drought episodes which cause significant damages and economic costs over extensive agricultural areas. Risk reduction, continuous vegetation monitoring, and management implementation are facilitated by complementary use of vegetation indices and biophysical parameters derived from satellite products (gridded data) within-situ data (point data). The paper focuses on:i) evaluating the extent and intensity of drought in Dobrogea, Romania, based on Normalized Difference Drought Index (NDDI) and Fraction of Absorbed Photosynthetically Active Radiation (FAPAR); ii) fires analysis, based on the Thermal Anomalies/Fire locations product (MCD14DL); iii)the correlation between the fires with the NDDI; iv) and the correlation between fires with the Land Surface Temperature (LST) product. The vegetation indices, biophysical parameters and fires are computed from Moderate Resolution Imaging Spectroradiometer (MODIS) daily and eight days’ synthesis products, during 22th of March - 29th of August 2000-2015. The results highlight the areas most affected by drought (moderate, severe and extreme) and fires in the Dobrogea.
