Migration has been most active among three major population movements and affective to population distribution.However,this paper first finds that the pattern of China's inter-provincial migration is robust since China's reforming and opening based on the analysis on the distribution of inter-provincial migration scale,intensity and population flow.Therefore,the continual migration in the past 80 years,especially since China's reforming and opening,has not changed the basic feature of China's population distribution and has no effective influence on the robustness of Heihe-Tengchong Line.The basic pattern of China's population distribution and Heihe-Tengchong Line mainly depend on the constant geographic position as shown in the First Nature Rule.Without any change of the First Nature Rule,China's population distribution and Heihe-Tengchong Line remain highly stable,and the migration is unlikely to lose the robustness.
