    不同植被恢复模式对矿区废弃地土壤养分的影响

    Effects of vegetation restoration models on soil nutrients in an abandoned quarry

    • 摘要: 以黑龙江省鸡西市采石场废弃地为研究对象,按照不同植被恢复模式进行土壤取样,测定养分含量。结果表明:植被的恢复能增加采石场废弃地的养分含量,各栽植类型中除土壤下层速效磷含量与对照地的比值小于1,下层有机质含量与对照地的比值大于10外,其他养分指标含量与对照地的比值在1.05~3.17。同种植被不同整地方式的土壤养分含量差异显著。客土保苗剂方式是对采石场废弃地进行植被恢复的最优整地方式。在植被恢复时间为5年后,客土和原土方式试验地的土壤养分含量在同一水平。

       

      Abstract: We investigated the nutrient content of soils under various vegetation restoration models in an abandoned quarry in Jixi City, Heilongjiang Province, northeastern China. The results show that restored vegetation can increase the soil nutrient content in abandoned quarry sites. In 5--10 cm deep soil layer, the ratio of the content of available phosphorus in the revegetated sites to that in the control (unvegetated) was less than 1, while the ratio of organic content to control was more than 10 and that of the content of other nutrients ranged from 1.05 to 3.17. Site preparation techniques also significantly affected soil nutrient content, of which the way of replaced soil + seedling agent was the best for vegetation restoration in this abandoned quarry. After five-year vegetation restoration, the soil nutrient content in the revegetated site showed similar levels between the addition of original soil and replaced one.
