Abstract

Abstract: In order to clarify the soil moisture content, pH value and variation characteristics of electrical conductivity in 0-50 cm soil layer under different vegetation types, soil samples collected under 5 vegetation types in Bayi Town, Linzhi were adopted as the study object. It was shown that land use type did influence the vertical distribution of soil moisture content, pH value and electrical conductivity in soil profile, especially the moisture content and electrical conductivity in the surface layer (0-20 cm). Moisture content of grassland exhibited aggregation as the moisture content was decreased with the deepening of soil layer. Soil moisture content and electrical conductivity showed stronger spatial variability, while the variation of pH value was smaller. With the deepening of soil layer, the variation of soil moisture content and electrical conductivity in different soil layers gradually decreased.

Key words: land use pattern, soil pH value, soil moisture content, electrical conductivity
