为明确不同植被恢复方法对边坡土壤中矿质营养、p H值和有机质含量的影响,在边坡恢复一年后对不同样地土壤中的养分元素、p H有机质含量等进行了测定。结果表明：种植细叶美女樱、红叶石楠、杜鹃等样地的土壤中氮元素增加最多,含量是新土的8.6倍。椰网防护加喷播的土壤中磷含量最高,是新土的8.3倍,喷播灌木丛马棘的磷含量则是新土的7.7倍。椰网防护加喷播处理钾含量是新土钾含量的6.5倍。喷播灌木丛马棘样地中镁含量最高,是新土的4.6倍。除了紫穗槐样地外所有样地p H值均小于7。相对于新土和煤矸石,所有处理样地中的各种有机质均有较大提高,但远低于自然群落中的含量。椰网防护样地的有机质含量...

In order to determine the effects of different vegetation restoration methods on the soil,the contents of mineral elements,p H value and organic matter in slope soil were determined after treated for one year. The results showed that the nitrogen element content of samples with planting Verbena tenera,Photinia × fraseri and Rhododendron simsii increased the most,8.6 times of that of new soil. The phosphorus content of sample treated with coconut network protection plus spray sowing soil increased the most,which was 8.3 times of that of new soi...
