Abstract:In order to analyze the properties of different soil types, and define the types of wind-erodible soil and explore their characteristics, the Yellow River Alluvial Area of Northeast Henan Province was taken as the research area. Field sampling and indoor experiment analysis were used to determine soil particle size, erodibility factor K value and other indicators, and then defined the types of wind-erodible soil in the area, and analyzed its spatial distribution feature. The main research results showed that: (1) In terms of soil types, there were four soil types in the Yellow River Alluvial Area of Northeast Henan, mainly fluvo-aquic soil, accounting for 65.57% of the area. In terms of subtypes, there were 11 soil subtypes. The main types were small zhejiang soil and sandy soil, accounting for 59.76% of the area. (2) In terms of the particle size composition of the soil, sandy soil, meadow aeolian sandy soil, salinized fluvo-aquic soil, and silt soil were dominated by sand. Other types were dominated by silt. Sandy soil, meadow aeolian sandy soil, irrigated fluvo-aquic soil, salinized fluvo-aquic soil had higher levels of erodible particles, with the range of 28.30%~31.36%. The K value of meadow alkaline soil, zhejiang soil and small zhejiang soil were relatively high, with the range of 0.038~0.041. (3) Comprehensively consider the two indicators of ‘the content of erodible particles ≥25%’ and ‘the erodibility is medium and above’, and the sandy soil, meadow windy sandy soil, irrigated and silted fluvo-aquic soil, salinized fluvo-aquic soil and degraded Fluvo-aquic soil were defined as regional wind-erodible soil. The wind-erodible soil area accounted for 41.79% of the study area, mainly in Zhongmou County, Xiangfu District, Weishi County and other regions. The results could provide reference and scientific basis for soil research and wind erosion control in the Yellow River Alluvial Area.
