江西红壤区不同岩性土壤抗蚀性变化特征研究

Study on Variation Characteristics of Anti-erodibility of Different Lithologic Soils in Red Soil Areas of Jiangxi Province

为探究不同岩性成土母质红壤抗蚀性的变化特征,以江西红壤区的红砂岩、花岗岩、第四纪红黏土3种典型岩性红壤为研究对象,通过室内试验分析了其基本理化性质、土壤质地状况、团聚体稳定性和抗分散能力,并对江西红壤区不同岩性土壤抗蚀性的变化特征进行了深入研究,以期为江西省红壤丘陵区水土流失防治、科学调整土地利用方式、提高土壤抗蚀性及土壤质量提供科学依据。

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.
