通过对距离德惠高速公路不同地点和不同季节的土壤pH值的比较分析,发现随着高速公路的运营,途经区防护林土壤pH值发生系列变化。土壤pH值随着距高速公路距离增加,土壤pH值逐渐增大。离公路越近,土壤的pH值越小。随着土壤深度的增加,pH值略增大。 pH值随着季节变化,呈现不同动态变化特征：春季>秋季>夏季。以上结果表明公路运营过程中大量汽车尾气中酸性物质累积对土壤pH值产生一定影响。加强运营高速公路两侧土壤的监测,能够为高速公路的生态影响评价及公路路域生态安全提供理论依据。

Soil pH values of different locations and seasons from Dehui expressway in the shelter forest were changed with the highway operation by comprising and analyzing. The soil pH values gradually increased with distance from highway. Soil pH values of sites where were closer to highway decreased. With the increase of soil depth, the soil pH values were slightly increased. The pH values varied with seasons, as followings, spring>autumn>summer. The results indicated that accumulation of a large account of acidic substances in au-tomobile exhaust had a certain impact on soil pH value during highway operation. In the future, the monitoring of soil from the highway should be emphasized, which will provide theoretical basis for the assessment of ecological impact of highway and safeguard ecological se-curity along the road.
