Wind erosion is one of the main drivers of soil loss in the world, which affects 20 million hectare land of Iran. Besides the soil loss, wind erosion contributes to carbon dioxide emission from the soil into the atmosphere. The objective of this study is to evaluate monthly and seasonal changes in carbon dioxide emission in four classes i.e., low, moderate, severe and very severe soil erosion and the interactions between air temperature and wind erosion in relation to carbon dioxide emission in the Bordekhun region, Boushehr Province, southwestern Iran. Wind erosion intensities were evaluated using IRIFR (Iran Research Institute of Forests and Ranges) model, in which four classes of soil erosion were identified. Afterward, we measured carbon dioxide emission on a monthly basis and for a period of one year using alkali traps in each class of soil erosion. Data on emission levels and erosion classes were analyzed as a factorial experiment in a completely randomized design with twelve replications in each treatment. The highest rate of emission occurred in July (4.490 g CO2/(m2·d)) in severely eroded lands and the least in January (0.086 g CO2/(m2·d)) in low eroded lands. Therefore, it is resulted that increasing erosion intensity causes an increase in soil carbon dioxide emission rate at severe erosion intensity. Moreover, the maximum amount of carbon dioxide emission happened in summer and the minimum in winter. Soil carbon dioxide emission was just related to air temperature without any relationship with soil moisture content; since changes of soil moisture in the wet and dry seasons were not high enough to affect soil microorganisms and respiration in dry areas. In general, there are complex and multiple relationships between various factors associated with soil erosion and carbon dioxide emission. Global warming causes events that lead to more erosion, which in turn increases greenhouse gas emission, and rising greenhouse gases will cause more global warming. The result of this study demonstrated the synergistic effect of wind erosion and global climate warming towards carbon dioxide emission into the atmosphere.

风蚀和季节变化对伊朗西南部土壤二氧化碳排放的影响

风蚀是全球土壤流失的主要驱动因素之一，影响了伊朗 2000 万公顷的土地。除了土壤流失，风蚀还会导致二氧化碳从土壤排放到大气中。本研究的目的是评估四类二氧化碳排放的月度和季节变化，即低度、中度、严重和非常严重的土壤侵蚀，以及与 Bordekhun 地区二氧化碳排放相关的气温和风蚀之间的相互作用。 ，伊朗西南部的布舍尔省。使用IRIFR（伊朗森林和山脉研究所）模型评估风蚀强度，其中确定了四类土壤侵蚀。之后，我们在每一类土壤侵蚀中使用碱收集器每月测量二氧化碳排放量，并持续一年。排放水平和侵蚀类别的数据在完全随机设计中作为析因实验进行分析，每种处理重复 12 次。7 月份的排放率最高（4.490 g CO2/(m2·d)）在严重侵蚀的土地上，在 1 月份最低（0.086 g CO2/(m2·d)）在低侵蚀的土地上。因此，导致侵蚀强度增加导致严重侵蚀强度下土壤二氧化碳排放率增加。此外，二氧化碳排放量最大的发生在夏季，而在冬季最小。土壤二氧化碳排放仅与气温有关，与土壤含水量无关；因为干湿季节土壤水分的变化不足以影响干旱地区的土壤微生物和呼吸。总的来说，与土壤侵蚀和二氧化碳排放相关的各种因素之间存在复杂的多重关系。全球变暖导致的事件导致更多的侵蚀，进而增加温室气体排放，而温室气体的增加将导致更多的全球变暖。这项研究的结果证明了风蚀和全球气候变暖对二氧化碳排放到大气中的协同效应。全球变暖导致的事件导致更多的侵蚀，进而增加温室气体排放，而温室气体的增加将导致更多的全球变暖。这项研究的结果证明了风蚀和全球气候变暖对二氧化碳排放到大气中的协同效应。全球变暖导致的事件导致更多的侵蚀，进而增加温室气体排放，而温室气体的增加将导致更多的全球变暖。这项研究的结果证明了风蚀和全球气候变暖对二氧化碳排放到大气中的协同效应。
