The invention relates to a resistance tomography sensitivity coefficient based on area increment in a high-conductivity flow field, which is characterized in that the area increment of a pixel is defined to be the sum of the areas of all neighborhood pixels; in any excitation and measurement mode, the area increment of one pixel in the flow field inevitably generates a boundary measurement value increment; the ratio of the measured value increment to the area increment is used for calculating a sensitivity coefficient based on the area increment in the high-conductivity flow field, and the sensitivity coefficient is used for representing the corresponding boundary measured value response when the pixel area has the unit increment. The invention also provides a detection object reconstruction and parameter detection method realized by adopting the sensitivity. 本发明涉及一种高电导率流场中基于面积增量的电阻层析灵敏度系数，其特征在于，定义一个像素的面积增量是它所有邻域像素的面积之和；在任何激励和测量模式下，流场中一个像素的面积增量必然产生边界测量值增量；将测量值增量与面积增量的比值用于计算高电导率流场中的基于面积增量的灵敏度系数，用来表征像素面积具有单位增量时
