Abstract:On the basis of the theory of modularity, the correlation between environmental factors and the modular structure of the Reaumuria soongorica population in the desert of Fukang, Xinjiang, was studied through analysis of the degree of relatedness adopted in the grey system theory. The results showed that 1) the canopy diameter (including the south_north and east_west diameter) is the important index representing the growth and development of Reaumuria soongorica population. Plant height is enhanced significantly with increasing canopy diameter. The grey relatedness degree is higher between the canopy and the modular factors of the first grade branch system and the present year branch system. 2) in a sense, the first grade branch system is the foundation for the whole plant while the third grade branch and the present year branch system are derived from the second grade branch system. The relationship among these factors indicates the integration in the modular structure of Reaumuria soongorica population. 3) in the first grade branch system, the relatedness degree is higher between the height and the number, length and angle, but lower between the height and the diameter. It demonstrates that the diameter does not completely resemble the former four modular factors of the first grade branch. As a result, some heterogeneity exists among these modular components of the first grade branch. 4) the modular characteristics of the second grade branch have higher relatedness degrees with the first grade branch system implying the integration of the modular factors. On the other hand, the grey relatedness degrees among the number, angle and diameter of the second grade branch system are higher, which shows, to some extent, that the modules change similarly and they reflect the other factors consistently. 5) the third grade branch and the present year branch system are also characteristics of the modular structure of Reaumuria soongorica populations. 6) generally, the relatedness degrees between the seventeen environmental factors investigated and the modules of the plant are higher relatively, which shows that the environmental factors strongly affect the growth and development of Reaumuria soongorica populations. Meanwhile, the paper indicates that the Cl - content and the conductivity of the soil are more important compared with the other factors. The total potassium content of the soil is a comparatively minor environmental factor for Reaumuria soongorica population.
