The present invention provides a method for generating a droplet array on a microfluidic chip, comprising the following steps: assembling an upper chip and a lower chip to an initial position, a fluid channel of the upper chip partially or completely covering a microporous array of the lower chip; injecting a solution into a chip, the solution being partially or fully filled in the microporous array of the lower chip; and relatively moving the upper chip and the lower chip to a liquid dividing position, the fluid channel of the upper chip and the microporous array of the lower chip being overlapped no longer, and the solution being dispersed into the microporous array to form a droplet array. A contact surface between the upper chip and the lower chip is hydrophobic, and the microporous array sufficiently separates the generated droplets physically, thereby avoiding cross-contamination. The present invention can effectively control the size and shape of the generated droplet.
