Review and Analysis of Soil Physical and Chemical Characteristics on Woodland Slope in Yuelu Mountain

Woodland Slope in Yuelu Mountain was chosen as studied area in this work.Soil bulk density,porosities,water content,organic matter and pH value were measured in the lab.Spatial heterogeneity in slope about the five soil physical and chemical characteristics was studied by statistical method.The results show that soil bulk densities change from 1.320 to 1.524 g·cm-3 and are higher in the lower slope than that in upper slope and middle slope.The soil porosities are between 44% and 51% and are lower in the lower slope than that in upper slope and middle slope.Surface soil water mass contents are more than 70% after continuous rainfall.Soil volume swells and swelling coefficient is 166%.Soil organic matter is probably between 2.4% and 4.2% and the order of organic matter contents is upper slope,middle slope and lower slope.The pH values are from 4 to 4.34.It denominates that the soil of Yuelu Mountain is the strongly acidic soil and suitable for acidic plants growing and developing.A negative correlation in significant level exists between organic matter contents and pH values.Spatial heterogeneity in slope about soil physical and chemical characteristics is no obvious difference.
