Based on the RTK GPS positioning technology, the basic physical and chemical properties and nutrient distribution of the collapsing pluvial fan were studied. Experiments with a typical collapsing pluvial fan had been made in Tongcheng County, Hubei Province. It was found that the content of alkali hydrolyzable nitrogen and available potassium were risen regularly with the increase of distance from the fan starting point and available phosphorus was increased enormously, but no prominent partial regularity increase was discovered. The study of the relationship between the nutrient contents and the main factors revealed that the main nutrient contents showed a linear distribution with the sampling elevation and the organic matter contents and a linear change with the square of clay content. The studied nutrients all shared a distinctive movement in the horizontal direction with the flood and the diffusion, and redistribution of alkali hydrolyzable nitrogen following the flood was more obvious than that of available potassium.
