采煤沉陷对水田水循环的影响

Impact of Coal Mining Subsidence on Water Circulation of Paddy Field

采煤沉陷区土地生态复垦是当前土地整治面临的主要现实问题之一。论文以重庆松藻矿区沉陷区受损水田为研究对象,采取野外考察和总结文献的方法,从水田水循环过程环节特征出发,主要对水田土壤水分剖面层次和水分运移速度及方向的可能性进行了系统分析,采煤沉陷对水田犁底层的入渗特性损毁是水田漏水的关键,这对于矿区土地资源利用与保护有重要的参考价值和现实指导意义。

Land reclamation of coal mining subsidence is one of the main problems facing the current land renovation. The damaged paddy field in Chongqing Songzao mining subsidence area was taken as research object, with field survey and literature summarization, from the feature of water cycle process of paddy field, the paddy field soil moisture profile and the possibility of moisture migration velocity and direction were systematically analysed. The impact of mining subsidence on infiltration characteristics damage of paddy field plow sole is critical to water leakage of paddy field, the study has important references value and practical significance for land resources utilization and protection.
