The spatial variation of soil physical and chemical properties in Funiu Mountain was studied to provide references
for identifying soil spatial variation mechanism in bordering land of China warm temperate zone and northern subtropical
region. Using vertical gradient sampling and traditional statistics method, the soil samples at the altitude from
1640 m to 1870 m were collected to compare physical and chemical properties between south and north slopes of the Funiu
Mountain. The results showed that soil pH, soil organic matter and soil total nitrogen were remarkably correlated with
altitude change, but soil electrical conductivity, soil available nitrogen, available phosphors, available potassium, and total
potassium were not related to altitude. With the increase of altitude, soil pH and total nitrogen increased, but soil organic
matter decreased. Compared with the soil properties of northern slope in Funiu Mountain, soil acidity, electrical conductivity,
and available nitrogen were higher in southern slope. Especially, the soil available nitrogen was much higher than
the mean value observed in northern slope samples. The contents of soil organic matter, available phosphorus, available
potassium, total nitrogen, and total potassium showed no striking difference on between southern and northern slopes. In
conclusion, both altitude and slope direction significantly influenced spatial variation of soil properties in Funiu Mountain.
It added to the boundary effect of Qinling Mountains, and revealled the interaction mechanism of the environmental
elements such as land-climate-soil-ecosystem in Funiu Mountain.
