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.
