江西红壤区不同岩性土壤抗蚀性变化特征研究OACSTPCD

In order to explore the variation characteristics of anti-erodibility of different lithologic red soils,three typical lithologic red soils in red soil areas of Jiangxi including red sandstone,granite and quaternary red clay were selected as the research objects,and the basic physical and chemical properties,soil texture condition,the stability and anti-dispersibility of aggregate were analyzed by laboratory test.The variation characteristics of anti-erodibility of different lithologic soils in red soil regions of Jiangxi were studied,in order to provide scientific basis for soil and water conservation prevention and control,scientific adjustment of land use,improvement of soil erosion resistance and soil quality in red soil hilly areas of Jiangxi Province.
