摘要

在干旱和半干旱地区,裸露和/或植被不足的土壤面临的最大问题之一是强风造成的风蚀。土耳其第二大风蚀区位于Aralık-Iğdır省。在本研究中,使用地理信息系统(GIS)绘制了40 km2风蚀区的表层土壤分析(粘土、%淤泥、%沙子、碳酸盐%、OM%、pH和EC)、干筛分析(4、2、1、0.84、0.42、0.106、0.020、0.84 mm、0.106 mm、>0.020 mm、EF1、EF2、SI和RSI值百分比)。结果表明,表层土壤风蚀区的质地等级为S-LS-SL,碳酸盐百分比为0.4-0.8,有机质百分比为0.3-2.4,pH值为8.0-9.1,电导率测量值为0.03-0.12。在干式筛分过程中;耐腐蚀材料(>0.84%)为0-40,侵蚀材料(<0.84%)则为43-99;用公式EF1计算的可侵蚀材料百分比为50-58,EF2为60-100;稳定性指数SI为0-1,相对聚集指数为RSI 0-11。已经确定,研究区域内所有地块的表层土壤对风蚀都很敏感,有些地块更敏感。

SOIL PROPERTIES AND MAPPING OF THE ARALIK-IĞDIR WIND EROSION AREA-I (SURFACE)
In arid and semi-arid regions, one of the biggest problems for soil which is bare and/or has insufficient vegetation is wind erosion caused by strong winds. The second largest wind erosion area of Türkiye is in the province of Aralık-Iğdır. In this study, surface soil analysis of 40 km2 of the wind erosion area (clay,% silt,% sand, carbonate%, OM%, pH and EC), dry sieving analysis (4, 2, 1, 0.84, 0.42, 0.106, 0.020, <0.020 mm), erodible fraction (EF1%, EF2%), stability index (SI) and relative aggregation index (RSI) were determined. In addition, elevation, slope, silt, >0.84 mm, 0.106 mm, >0.020 mm, EF1, EF2, SI and RSI values as percentage were mapped using Geographic Information Systems (GIS). As a result, the texture classes of the wind erosion area of surface soils were determined as S-LS-SL, the carbonate percentages as 0.4-0.8, the organic matter percentages as 0.3-2.4, the pH values as 8.0-9.1, the electrical conductivity measurements as 0.03-0.12. In dry sieving processes; the resistant material (>0.84%) as 0-40, the erosive material (<0.84%) as 43-99; the erodible material percentages calculated with equations EF1 as 50-58, EF2 as 60-100; the stability index SI as 0-1 and the relative aggregation indices were RSI 0-11. It has been determined that the surface soils of all plots in the study area were sensitive to wind erosion, and that some plots were more sensitive.
