摘要

气候变化对人类、动物和植被等许多生命系统都有直接或间接的影响。本研究利用美国国家航空航天局（NASA）卫星提供的伊拉克尼尼微和瓦西特地区 1981-2021 年期间的月降水量和温度以及 2000-2022 年期间的植被图像（NDVI）来了解它们在空间和时间上的变化。研究发现，在这两个研究地区，气温随着时间的推移不断升高，但降水量却处于波动上升的状态。植被的分布也随着时间和区域的变化而变化。植被面积随着降水量的增加而增加，尼尼微地区的植被面积大于瓦西特地区。当降水不足时，两个研究地区的植被覆盖面积都会减少。温度升高也导致植被密度和面积减少。研究发现，降水量的变化比温度变化对植被分布的影响更大。

Climate changes impact on the distribution of vegetation in Wasit and Nineveh regions of Iraq

Climate changes have a direct or indirect impact on many vital systems, including human and animal, as well as vegetation. The monthly precipitation and temperature for the period (1981-2021) and vegetation images (NDVI) for the period (2000-2022) from the satellite (NASA) for the regions of Ninevah and Wasit of Iraq were used to find out their variations over the space and time. It was found that the temperature was increasing with time, but the precipitation was in a state of turbulent increase in the two study areas. The distribution of vegetation was also in a state of change with time as well as within a region. The vegetation area increased with increase in precipitation which was greater in the Ninevah region than in the Wasit region. When there was a lack of precipitation, the vegetation cover area decreased in the two study areas. The increase in temperature also resulted in a decrease in the density and area of vegetation. It was found that the change in the amount of precipitation was more influential than the change in temperature on the vegetative distribution.
