At the same time, to find out the measures to improve and strengthen students’ physical health level, so as to offer objective and scientific evidence and suggestion for the hygiene of physical training in schools.Methods: Collecting the data of three surveys on physique and health condition for the teenagers with Hani and Han nationality in Honghe Prefecture, Yunnan province in the past decade. Generally, the school that is used for the survey should be the same one with the past years, and the method for sampling is cluster sampling. At first, it is reasonable to decide the sample school, then, according to the grade, taking each class as a group, to take the method of random group sampling. In strict accordance with the National student physical health condition survey manual, this survey is conducted with unified testing machine and method, as well as the uniform data entry software.Result: According to the result, this paper has done a comprehensive cause analysis. With the rapid development of economy, multiple factors such as heredity, lifestyle, environment and the level of sports and health education directly affect the growth and development levels and physical quality of the students. Nowadays, the students’ nutritional need can be basically satisfied, according to the increase of the indexes such as height, weight, chest circumference, physique and the ververck Index, we can see the students’ growth and development level obviously improves, and the growth rate is tend to be ahead of time. However, it increases the level and rate of students’ growth, at the same time, it restricts the development of their physical fitness. Because of the many students are lack of effective exercise, thus causing the generally decline of their body function and physical quality for both the students with Hani and Han nationality in nearly 10 years. As for the vital capacity, generally, the index of both Hani and Han nationality students rises, but in the second half of the decade, the vital capacity of Hani students is tend to decline, and that of the Han students shows a small increase. From the perspective of strength quality, the grip strength of Hani students is in a sustainable growth, while that of the Han students continues to decline in the past 10 years. The testing results of standing broad jump for both Hani and Han nationality are declining. As for the speed quality, both Hani and Han nationality students are tend to rise in overall in the past 10 years. And when it comes to the index of flexibility quality, the testing result of the sit-and-reach for both Hani and Han nationality students rises in overall, but it declines during the second half of the decade, and it declines significantly in addition to the Han girls.

Among which, the testing result of Hani students declines obviously in the first five years, and that of the Han girls falls in the second five years. There are respective differences and characteristics for the development of Hani and Han nationality teenagers in Yunnan province during the past 10 years. The index of body shape for Hani students continues growth, and compared with the rapid trend of physique development, the indexes of students’ function and quality show a trend of stagnation or decline.Conclusion: To be specific to the problems existing in the physical health development of the students in Honghe prefecture, Yunnan province, in future, being based on improving the quality of the whole nation, the educational administrative department should adhere to the guiding ideology of "health first", further strengthen the students’ health education and the prevention and control to the common diseases, reinforce the supervision mechanism of physical education in schools, and enhance the supervision, increase the expenditure, what’s more, establish and adhere to the scientific and standardized diet and rest plan for students.
