On the basis of the theory of biological modularity,the correlation between environmental factors and the modular structure of Cultivation Brassica campestris in Tibet was studied through analysis of the degree of relatedness adopted in the grey system theory.The results showed that: ⑴ the numbers of plant silique,the numbers of seed of silique and the weight of 1000 seeds are the important index representing the growth and constituted of cultivation Brassica campestris in Tibet,weight is significantly increasing with the numbers of plant silique and the weight of seed.⑵ The stem system is the foundation for the whole plant.The relationship among these factors indicates the integration in the modular structure of cultivation Brassica campestris population.⑶ Generally,the related degrees between the seven environmental factors investigated and the modules of the plant are higher relation,which shows that the environmental factors strongly affect the growth and distribution of cultivation Brassica campestris population,.Meanwhile,the paper indicates the temperature and sunshine are more important compared with the other factors.The precipitation is a subordinate environment factor for Cultivation Brassica campestris population.
