The importance of relative relief as a geographic factor is gradually being realized, but its significance in relation to both physiography and human activi-ties has hardly been appreciated. The present paper tries to elucidate relative relief in its manifold relations, using Tsunyi District of Kweichow Province as an example. With the 1/50,OOOth new Ordnance maps as the base, the writer has prepa- red a relative relief map for the region which stretches 92 km. from north to south and 73 km. from east to west, covering an area of 6,700 sq. km. The base maps are divided into small squares each measuring 2 x 2cm., with an area of about 1 sq.km. and the difference of height between the highest and lowest points in each square is noted.
