叙利亚战争对植被的影响

Impacts of the Syrian Civil War on vegetation

战争不仅会造成大量的人员伤亡和经济损失,还可能对环境带来不利影响。利用2001—2018年长时间序列卫星遥感数据探究叙利亚地区植被生长对战争所引起环境变化的响应,结果表明,叙利亚战争冲突最为激烈区域的植被指数存在较为明显的下降趋势,从战争开始的2011—2015年,土地类型变化并不显著,但在2015—2018年之间,土地类型发生了较大的变化。18 a间,草地面积减少了10.08%,农作物种植区面积减少21.87%。研究进一步探索了人为因素对植被状态的影响,发现东部幼发拉底河两岸及延伸区域受人为因素影响最为显著。研究揭示了战争给植被生长带来的负面影响,对于军事冲突地区粮食安全等方面研究与战略制定具有参考意义。

Besides numerous casualties and economic losses,wars may cause damage to the environment.Using a long time series of satellite remote sensing data from 2001 to 2018,this study explored the response of vegetation growth to the environmental changes in Syria caused by the Syrian Civil War.The results are as follows.The vegetation index significantly decreased in regions that experienced the most intense conflict in the war.The land types changed slightly from 2011 when the war started to 2015 but changed significantly from 2015 to 2018,with the grassland area decreasing by 10.08%and the crop planting area decreasing by 21.87%.This study further explored the impacts of human activities on the vegetation status,revealing that both sides of the Euphrates River in the east and their extensional areas are most significantly affected by human activities.This study discovered the negative impacts of the war on vegetation growth and can be utilized as a reference for the research and strategy formulation on food security in areas with military conflicts.
