Effect of Fire Disturbance on Soil Physical ＆ Chemical Properties of Forest
Physical ＆ chemical properties of forest soil were studied one year after ＂3 · 29 forest fires＂ in 2006 in Anning city. Result shows that compared with unburned area, soil bulk density significantly increases after being burned;soil water content reduces after being burned. In eluvial horizon of soil, pH value raise slightly ; the contents of organic matter, availa- ble nitrogen ＆ total phosphorus decline somewhat;the contents of total potassium and available potassium increase obvious- ly; the rest indexes did not change significantly. In illuvial horizon of soil, except of pH value and total phosphorus, Other traits increase in varying degrees.
