| 摘 要： | 为了更好的研究草炭土湿地基本信息,获取草炭土分布特征,选择吉林省东部沼泽草炭土湿地为研究对象,运用高密度电阻率法,对比不同装置下探测结果的差异,再与已知的探槽资料做对比,得出温纳—施伦贝格装置为最可靠、最合理的探测装置。再将该装置运用到其他草炭土地区,得出对草炭土湿地的探测为浅层地质问题,草炭土的视电阻率为50~300Ω·m,深度为1.2~3.9 m,在反演图像中表现为低阻体部分,各地层间层状结构明显,电性界限分明。

| Abstract: | In order to study the basic information of turfy soil wetland, and to obtain its distribution characteristics, the authors chose the turfy soil wetland in eastern Jilin Province as the research site. The difference of detection results under three devices are compared using high-density resistivity method, and then compared with the known data of the trench. It shows that Winner-Schellenberg device is the most reasonable and most reliable device. This device was subsequently used in other turfy soil areas to obtain the resistance of turfy soil and its distribution. The apparent resistivity of peat soil is 50~300 Ω·m at depths of 1.2~3.9 m. In the inversion images, the turfy soil is characterized by low resistance, with obvious layers and electricity boundary. |
