Surface coal mining activities have numerous consequences on terrestrial ecosystems. Loss of soil and biomass carbon pool due to mining activities is a serious concern in the rapidly changing environment. We investigated the effect of fast-growing trees (Albizia lebbeck, Albizia procera, and Dalbergia sissoo) on soil fertility and ecosystem carbon pool after eight years of afforestation in the post-mining land of Jharia coalfield, India, and compared with the adjacent natural forest site. Significant differences in soil organic carbon (SOC) and total nitrogen (TN) stocks in afforested mine soil and natural forest soils were observed. Greater SOC stock was found under D. sissoo (30.17 Mg·C·ha⁻¹) while total N stock was highest under A. lebbeck (4.16 Mg·N·ha⁻¹) plantation. Plant biomass accumulated 85% of the natural forest carbon pool after eight years of afforestation. The study concluded that planting fast-growing trees in post-mining lands could produce a promising effect on mine soil fertility and greater carbon storage in a short period.

速生树木对绿化煤矿地（印度）土壤性质和碳储量的影响

露天煤矿开采活动对陆地生态系统有许多影响。在瞬息万变的环境中，采矿活动造成的土壤和生物量碳库损失是一个严重的问题。我们调查了印度Jharia煤田采后土地造林八年后，快速生长的树木（Albizia lebbeck，Albizia procera和Dalbergia sissoo）对土壤肥力和生态系统碳库的影响，并与邻近的自然环境进行了比较森林站点。观察到绿化的矿山土壤和天然森林土壤中的土壤有机碳（SOC）和总氮（TN）储量存在显着差异。在D. sissoo（30.17 Mg·C·ha ^-1）下，SOC含量更高，而在Lebbeck（4.16 Mg·N·ha ^-1）人工林。经过八年的造林，植物生物量累积了天然森林碳库的85％。研究得出的结论是，在采后土地上种植速生树木可以在短期内对矿区土壤肥力和更大的碳储量产生有希望的影响。
