Pingo and Alas are unique landscape structure in permafrost zone, and there is large variation of vegetation from Steppes to aquatic swamp in the Central Yakutia. This vegetation is growing on dry-wet environmental gradient, and it may be affected by recent anthropogenic effect and climate change. In this paper field observation of 3 Pingo transect and literature studying about Central Yakutian vegetation were coupled to understand the nature of permafrost zone which may vulnerable for further climate change. Steppe vegetation, which appeared on the top of Pingo, has its longer history as dynamics of Alas formation since Late Pleistocene from literature. Surface disturbance and thermokarst depression alter the type of vegetation on the top of Pingo. In contrast, more diversified swamp vegetation covered foot of the hill slope. 3 viewpoint of variation in the observed 3 Pingos vegetation were noticed as size-effect, stability of soil and anthropogenic effect. These sights will help to understand condition of Pingo from outside, and it may provide possibility to assess permafrost stability for future.
