Provided is a multi-flux micro-fluidic chip including a chip body. The chip body includes a fluid inflow cavity communicated with an external air path, reaction-quantification cavities, waste liquid cavities, and a fluid path distribution cavity disposed at a middle position of the chip body. The two or more reaction-quantification cavities are distributed on two sides of the fluid path distribution cavity in rows to form the first and second row of reaction-quantification cavities respectively; and they are communicated with a fluid outlet of the fluid path distribution cavity through fluid path branches, and a fluid inlet of the fluid path distribution cavity through fluid path branches, and a fluid inlet of the fluid path distribution cavity is communicated with a fluid outlet of the fluid inflow cavity and an external fluid path, which making it possible to detect multiple items simultaneously and greatly improving the flux of the micro-fluidic chip.
