【Abstract】 In this paper, the authors make use of satellite photograph, aerial photostat and the geomorphlogical map in large scales synthetically and apply the method of mathematical sampling as well so as to complete the mathematic statistics of distribution and occupied area of inhabitantsin in twelve counties of Tiensui district, gansu province. The paper provides means,methods and guantitative indices for agricultural division and national land rectification, for the establishment of mathematic geography model of inhabitant area and for solving the difficult problems of small scale and low efficiency with regular method in using satellite photographs.更多还原
