利用D IVINER2000含水量测定仪定位测定了自燃煤矸石山深度为0—100 cm的黄土矸石复合层、黄土层和裸露矸石层水分体积含水率的季节变化和垂直变化,根据水分含量变化规律将自燃煤矸石山的水分季节变化分为4个时段:土壤水分消耗期(3—6月)、土壤水分积累期(7—8月)、土壤水分消退期(9—11月)和土壤水分稳定期(12—2月);通过标准差将自燃煤矸石山土壤水分的垂直变化分为速变层、活跃层和相对稳定层。上述研究结果可以为自燃煤矸石山的生态构建提供重要理论依据,为以水分动态平衡为基础的植被恢复和建设提供数据支持。
The seasonal and vertical changes of water volumetric moisture content of loess gangue composite layer, loess layer and exposed gangue layer were measured by D IVINER 2000 water content measuring instrument. According to the variation law of water content The seasons of spontaneous combustion coal gangue are divided into four periods: soil water consumption period (March-June), soil water accumulation period (July-August), soil moisture subsidence period (September-November) and soil moisture Stable period (December-February); the vertical variations of soil moisture in spontaneous combustion coal gangue hills were divided into fast changing layer, active layer and relatively stable layer by standard deviation. The above results can provide important theoretical basis for ecological construction of spontaneous combustion gangue hill and provide data support for vegetation restoration and construction based on water dynamic balance.
