不同植被对黑岱沟露天煤矿复垦土壤微生物数量的影响

摘要

土壤微生物数量是评价土壤微生物重要的调控功能参数.通过研究不同复垦年限的土壤微生物数量,分析在不同年限下不同植被对土壤微生物数量的影响,探讨不同植被对土壤微生物的作用特点.研究结果表明,灌木混交林为提升露天煤矿土壤质量的最佳手段.%Soil microorganism quantity is an important adjusting function parameter to evaluate the soil microbes. Through researching soil microorganism quantity of different reclamation time, the article analyzes the effect of different vegetation on soil microbes, and explores the function characteristics of different vegetation on soil microbes. Based on the results, the mixed forest of Shurbs is the best way to improve the soil properties in the open-pit coal mine.
