采煤沉陷对水田土壤水系统的影响及改良对策——以重庆松藻矿区为例

采煤沉陷区土地生态复垦是当前土地整治面临的主要焦点问题之一。以重庆松藻矿区沉陷区受损水田为研究对象,通过实地考察和文献总结,分析水田土壤水系统组成特征,系统探讨了采煤沉陷前后土壤水系统的含水土壤剖面层物理特性和土壤水流入渗状态,针对这些变化提出了矿区生态恢复和土地复垦的具体对策。 

Effect of coal mining-induced subsidence on the soil water system of rice paddy and its countermeasures of invprovement: A case study of Songzao miming area

At present, ecological reclamation of land in mining-induced subsided area is one of the focus problems that the land management is facing. The paper, taking the mining-induce subsided area in Songzao mining area as object of research, through site investigation and literature summarization analyzed the composition characteristics of the soil water system of paddy field, systematically discussed the physical characteristics and the infiltration status of water flow in water-bearing soil section of soil water system before coal mining, aiming at the changes, put forward the concrete countermeasures for ecological restoration and land reclamation in mining area.
