| 摘 要： | 按不同植被恢复模式,对汾西集团矿区煤矸石山植被恢复2年的土壤养分进行分析,采用综合评价方法对土壤养分质量进行定量评价。结果显示,植被恢复对煤矸石山土壤速效氮和有机质改良效果较差,对速效磷和速效钾改良效果较好。4种植被模式中,恢复土壤养分综合指数的大小依次为:高羊茅—紫花苜蓿混交模式,紫穗槐纯林,高羊茅—紫花苜蓿—紫穗槐,高羊茅—黑心菊—波斯菊。

| Abstract: | Soil nutrients of gangue pine under different vegetation restoration patterns were analyzed after 2 years restoration in FenXi Mining Group, and the quality of soil nutrient was assessed quantitatively by comprehensive evaluation. The results showed that the improvement of available N and organic matter in soil was poor by vegetation restoration, while the content of available P and available K in soil was improved. The index of comprehensive soil nutrient was arranged in the descending order as mix of Festuca elata G. and Medicago sativa L. , Amorpha fruticosa L. , mix of Festuca elata G. , Medicago sativa L. and Amorpha fruticosa L. , mix of Festuca elata G. , Rudbeckia hybirta and Cosmos bipinnatus Cav.. |
