摘要： 本文研究了焚烧对芨芨草滩地草场上壤生态条件的影响。结果表明,焚烧可使土壤温度升高,地表可升温3.2～10.8℃,地表以下土层也有所升温,但其数值随深度增加而递减。焚烧后土壤含水量在0～40cm土层内可增加2.42～4.58%,土壤含盐量和土壤含磷量均有增加,但土壤含氮量则有所下降。

Abstract: In this experiment we study the effect of burning on main ecological factors of splendid achnatherum lowland range.The results showed:After burning, soil surface temperature were 3.2-10.8 C higher in the burned plots than in the unburned plots.The numerical values, which temperatures under soil surface were also higher in the burned plots, decreased progressively with the depth increase.Burning lend to the soil mositure content increasing 2.42 - 4.58% in 0-40cm soil layer.Being burned, the soil salinity and the soil phosphorus content increased slightly, but the soil nitrogen content decreased in the burned plots.

Key words: Burning, Splendid achnatherum, Ecological factor of soil
