%X By testing and analysing saturated water conductivity,water characteristic curve and water constants in sandy soi with different organic matter contents,the relationship between sandy soil organic matter and hydrodynamic parameters i; studied.The results show that there are linear relationships between sandy soil organic matter and water parameters: thf higher the soil organic matter content,the greater the soil water content under same soil water suction;there is a very remarkable negative linear relationship between the soil saturated water conductivity and the soil organic matter content anc <0.01 mm physical clay;the soil organic matter is the most important influence factor on soil hydrodynamic parameters ir sandy soil.
