By combining with geographic and climatic factors, the author probed into the characteristics, patterns and trend of the variation of de-velopment of students of minority nationalities in these areas as follows: (1) the level of development of students of minority nationalities in plateau areas has been uplifted to a certain extent; their development has entered into a fast growing period; the average growth of chest circumference of the male students (except those of Naxi nationality) decreases to different extents, while that of the female students increases to different extents; the overall level of development of students of Naxi and Zang nationalities is better than that of students of Qiang and Tu nationalities; (2) the peak age of sudden increase of height of students of minority nationalities in plateau areas (except that of female students of Naxi nationality) is advanced by 1 to 4 years, while the peak age of sudden increase of weight of these students is advanced by 1 to 2 years except that there is no change for female students of Tu nationality, but the peak age of sudden increase of chest circumference does not change significantly; (3) the peak of height velocity of student of minority nationalities in plateau areas does not change significantly, the maximum annual growth of most of the students in 2005 is greater than that in 1985; the peak of chest circumference velocity and maximum annual growth of most of the students in 2005 are greater than those in 1985.
