| 为明确不同植被恢复方法对边坡土壤中矿质营养、pH 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、pH 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pH 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
最高，是新土的 11.0 倍；喷播灌木丛马棘的样地、喷播形成的草坡样地等样地也较高；增加最少的是种植佛甲
草样地，是新土的 4.0 倍。结果表明，椰网防护加上喷播技术能在较短时间内增加土壤中的矿物质和有机质的
含量，有利于植物生长。 |

| In order to determine the effects of different vegetation restoration methods on the soil，the contents
of mineral elements，pH 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 soil，
while the phosphorus content of sample treated with Indigofera pseudotinctoria increased by 7.7 times. The potassium
content of sample treated with coconut network protection plus spray seeding increased the most，6.5 times of that
of new soil. The Magnesium content of sample with I. pseudotinctoria increased the most，4.6 times of that of new
soil. The pH values were less than 7 except the sample treated with Amorpha fruticosa. Compared to the new soil and
coal gangue，the contents of organic matters of all treatments greatly improved，but far less than those of natural
community. The organic matter content of sample treated with coconut network protection plus spray sowing increased
the most，11 times of that of new soil. The organic content of the sample with planting I. pseudotinctoria and sample
with glass were high. The less increase of organic matter content was found in the sample with Sedum lineare，4 times
of that of new soil. Those results show that the coconut network protection plus spray sowing technology is the most
suitable for the slope revegetation，because it could
increase the contents of mineral elements in the soil and
organic matter content in a relatively short time，which
is conducive to the growth of plants. |
