[ Objective] The study aimed to analyze the response of soil nutrient content to soil loss in karst sloping land of Southwest China. [Method] Choosing a karst sloping land in Nanchuan, Chongqing City as a sampling area, we analyzed the basic physical and chemical properties of soils at different sampling points, as well as the movement of Mg, Cu, Zn, Mg, Mo and Mn in the soils. [ Result] In the sloping land, there was a var- ying decrease in the content of all soil nutrients from the top to the bottom, but there was no obvious deposit at the bottom. In addition, Mg, Cu, Zn, Mg, Mo and Mn conte...
