The invention discloses a pulse type water distribution device. The device comprises a water distribution tank and a tubular automatic water inlet and outlet device. The pipe type automatic water inlet and outlet device comprises a water inlet pipe, a hose, a water outlet pipe and a water retaining structure; the water outlet pipe is arranged at the bottom of the water distribution tank and penetrates out through an opening; the water inlet pipe passes through the hose and the water outlet pipe, and the gravity of the water inlet pipe is less than or equal to the buoyancy force borne by the water inlet pipe; and the water retaining structure is arranged in the water inlet pipe and can be opened or closed along with change of the position of the water inlet pipe. In a water storage period,the water inlet pipe floats upwards along with the rise of the liquid level in the water distribution tank; when the water inlet pipe floats upwards to a highest height, the water retaining structureis closed, the liquid level is higher than a front end pipe opening of the water inlet pipe, and water flows into the water inlet pipe for water storage for a short time, so that the self weight of the water inlet pipe is increased and the water inlet pipe starts to sink, and then the water retaining structure is opened; and when the water inlet pipe sinks to the bottom of the water distribution tank, the liquid level is lower than the pipe opening of the water inlet pipe, and then a drainage period is completed, so that the process is circulated to form pulse type water distribution. The pulse type water distribution device has a simple structure, high efficiency and stable performance, and can realize hydraulic automatic adjustment, adju
