The invention discloses a water supply method of a Huizhou traditional scene building group based on the remote sensing technology. By means of the remote sensing information technology, the deep structure of a traditional settlement is detected, wherein distribution, storage and use condition of the water table under the traditional scene buildings are detected; water supply transformation is carried out in time on the traditional settlement area where groundwater is overused; on the premise that the traditional architectural scene is unchanged, a waterworks outside the traditional scene building area provides water for the traditional scene building area. According to the water supply method of the Huizhou traditional scene building group based on the remote sensing technology, by means of the remote sensing information technology, the groundwater in the traditional scene building area is detected, and based on the detection result, an area which needs outside water supply is defined; a main pipe is laid outside the traditional scene building area, by means of network branch pipes, water is supplied to the inside of the building area, and construction quantity inside the traditional scene building area is reduced, so that the original scene of the traditional building group is better protected.
