The invention discloses an underground layering slim tube flowmeter and a flow testing method thereof. The underground layering slim tube flowmeter comprises a connecting body and a plurality of slim tube flowmeters arranged on the connecting body, the connecting body is used for connecting pipelines of adjacent layers, one end of the connecting body is provided with a first main flow channel in the axial direction, a plurality of branch flow channels corresponding to the slim tube flow meters are formed in the inner wall of the first main flow channel, the branch flow channels are communicated with inlets of the corresponding slim tube flow meters, a second main flow channel is formed in the other end of the connecting body, and overflowing openings are formed in the side wall of the second main flow channel. The overflowing openings are communicated with outlets of the corresponding thin tube flow meters, and fluid sequentially passes through the first main flow channel, the branch flow channels, the thin t
