The invention discloses a touch baseplate, a touch positioning method thereof and a capacitive touch screen. The touch baseplate comprises a substrate baseplate and a plurality of mutually independenttouch electrodes disposed on the substrate baseplate in a single-layer manner. All the touch electrodes are divided into first touch electrodes and second touch electrodes all alternately disposed ina first direction and a second direction. All first touch electrodes of at least one row or column are connected through wires, or all second touch electrodes of at least one row or column are connected through wires. Different from a technical scheme that one touch electrode is connected with one wire and a plurality of touch electrodes are mutually independent in the prior art, all the first touch electrodes or second touch electrodes of the at least one row or column are connected in the touch baseplate through the wires, thus compared with the prior art, the touch baseplate can reduce thenumber of the wires, correspondingly reduce the number of touch pins which are in one-to-one correspondence connection with the wires in a touch chip, and thus reduce an area occupied by the touch chip.
