A GIS project was created in ArcGIS format. Spatial geographical analysis using GIS-technologies was carried out. The results of the spatial analysis are reflected in the form of a map of the zoning of the alas. The quantitative characteristic of alas is given. It was revealed that the alas are 7,04 percent of the total area of the Megino-Kangalassky ulus. When analyzing the distribution of alas by heritage, it turned out that they are most common in the Dogdoginsky heritage (48,5 percent of the total territory). Less than all, about 1 percent, alas are found in the Chyamayykinsky heritage. A map of the distribution of bulgunnyakhs on the territory of the Megino-Kangalassky ulus was compiled. It is characteristic that most often bulgunnyakhs are found in the central and northern parts of the ulus.
