摘  要：
为探讨种植杠柳(Periploca sepium)与鸡矢藤(Paederia scandens)对高速公路边坡土壤质量恢复效果,对其下0~10 cm、10~20 cm、20~30 cm土层的土壤理化性质及生物活性进行研究,与传统护坡植被紫穗槐(Amorpha fruticosa)进行比较,通过主成分分析,对3种植被恢复下土壤质量进行综合评价。结果表明:土壤养分及酶活性基本表现为鸡矢藤植被下最高,微生物数量为紫穗槐植被下最高;土壤含水量、土壤养分、微生物数量及酶活性均表现出随着土层加深不断递减,土壤容重和pH则相反;土壤微生物数量和土壤酶活性均呈现季节变化;土壤质量综合评价结果表明,鸡矢藤(0.33)>紫穗槐(-0.11)>杠柳(-0.21),鸡矢藤对土壤质量恢复效果最好,优于传统护坡植被紫穗槐,杠柳对土壤的恢复能力与紫穗槐相差不大,因此鸡矢藤与杠柳均可作为优良的高速公路护坡植被进行推广应用。

摘  要：
To explore the effect of planting Periploca sepium and Paederia scandens on soil quality restoration of highway slope,the season dynamic of soil physical and chemical properties,microbial quantity and soil enzyme activity were studied at soil depth of 0-10 cm,10-20 cm and 20-30 cm under two kinds of vegetation compared with the traditional slope protected vegetation Amorpha fruticosa,and the comprehensive evaluation of soil quality under the three plants was analyzed by principal component analysis.Results showed that:(1) Various nutrient indices and soil enzyme activity were higher under Paederia scandens,and the soil microorganism quantity was the highest under Amorpha fruticos;(2) The contents of soil moisture and soil nutrient,microorganism quantity and enzyme activity declined with soil layer while the soil bulk density and p H appeared an opposite trend;(3) Microorganism quantity and soil enzyme activities presented seasonal change;(4) Comprehensive evaluation results of soil quality showed Paederia scandens(0.33) > Amorpha fruticosa(-0.11) >Periploca sepium(-0.21).Paederia scandends was the best to soil quality restoration,and the restoration effect of soil quality was nearly similar between Amorpha fruticosa and Periploca sepium.Paederia scandens and Periploca sepium both could be used as excellent vegetable types for highway slope protection.
