Abstract: Among several paterns of species diversity variations, perhaps the most widely recognized one is the increasethat occurs from the poles to the tropics. A number of explanations have been put forward for this generallatitudinal trend in species diversity. Among these, it seems that the ESA hypothesis is more reasoanable.Based on the explanations advanced before, the author has proposed his own idea, that is the factors, whichinflunce the distribution of species, can be divided into two categories, one is environmental, another is biological, and the environmental factor is primary, the biological one is secondary.
