造林对乌海露天煤矿复垦地土壤养分和碳库的影响

以造林前的荒草地和造林后的林地为研究对象，研究造林前后土壤无机碳库、活性有机碳库、慢性有机碳库、惰性有机碳库、养分的变化规律以及各养分指标对碳库贡献率的差异。研究结果表明造林能够明显改善和提高土壤养分状态和碳库水平。

Taking uncultivated grasslands prior to afforestation and afforested woodlands as the research objects, this study examines the variation patterns of soil inorganic carbon pools, labile organic carbon pools, slow organic carbon pools, recalcitrant organic carbon pools, and soil nutrients, as well as the disparities in the contribution rates of various nutrient indicators to different carbon pools. The research results demonstrate that afforestation can significantly improve and elevate soil nutrient status and carbon pool levels.
