- 摘要:
- 研究不同复垦年限煤矸山土壤微生物功能菌差异及其影响因素有助于揭示煤矸山复垦土壤质量变化情况，为煤矸山植被复垦提供理论指导。以山西省曹村煤矿复垦4 a（R4a），6 a（R6a）和8 a（R8a）煤矸山为研究对象，分析了3种复垦年限土壤好氧固氮菌、氨化细菌、纤维素分解菌、有机磷细菌和无机磷细菌数量变化及其与土壤理化性质的关系。结果表明：随着复垦年限的增加，功能菌总量呈增加趋势；好氧固氮菌、氨化细菌、有机磷细菌、无机磷细菌均呈增加趋势，但纤维素分解菌呈先升后降的趋势。相关分析表明，氨化细菌和纤维素分解菌受土壤理化性质的影响最大；主成分分析结果表明，有效磷、碱解氮、含水量是影响微生物功能菌的主要因子。
- Abstract:
- To reveal the change of soil quality in the reclamation coal waste pile and provide theoretical guidance for coal waste pile vegetation reclamation, soil microbial functional bacteria and the influence factors on coal waste pile in different reclamation years were studied. The reclamation lands of 4 a (R4a), 6 a (R6a) and 8 a (R8a) after reclamation on coal waste pile were taken as the case in Cao Village coal mine of Shanxi Province. The changes of soil aerobic nitrogen fixing bacteria, ammonifying bacteria, cellulose decomposing bacteria, organic phosphorus and inorganic phosphorus bacteria of 3 kinds of reclamation years and the relationship between the soil function microbe and the soil physical-chemical properties were analyzed. The results showed that the total amount of bacteria presented the rising trend with reclamation years, aerobic nitrogen fixing bacteria, ammonifying bacteria, organic phosphorus bacteria and inorganic phosphorus bacteria increased with reclamation years, but the cellulose decomposing bacteria first increased and then decreased. Correlation analysis showed that ammonifying bacteria and aerobic cellulose decomposing bacteria were significantly affected by soil properties, and the principal component analysis showed that soil available phosphorus, available nitrogen, soil moisture content were the main factors influencing soil microbial functional bacteria.
