摘    要:主要针对2006年3月29日安宁火灾后1年的森林土壤理化性质进行研究,结果表明,与未过火区相比,火烧后1年,过火区域的土壤密度明显增加,土壤自然含水量明显下降;淋溶层土壤的pH值略有上升,有机质、水解N、全P含量有所下降,全K与速效K含量明显上升,其余指标变化不明显;淀积层土壤除pH值、全P下降外,其余各指标均有不同程度的提高。

关 键 词:火干扰  森林土壤  土壤理化性质

Abstract: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.
Keywords:fire disturbance  forest soil  soil physical & chemical properties
