A Spatial Database of Ecosystems of the Lake Baikal Basin

摘要

Abstract A database, including a map layer of ecosystems of the Lake Baikal basin, has been compiled at a scale of 1 : 500 000. The area is divided into 71 types of mesocombinations of plant communities and their anthropogenically transformed variants, which reflect natural units, corresponding to the level of urochishche/suburochishche of landscapes. A digital map layer of morphogenetic relief types (31 were specified) was elaborated to reflect the spatial variability of the distinguished geobotanical units. The map layer of the soil cover of the basin was based on interpolation of various published thematic data and supplemented by archived and long-term data of terrain survey of the soil cover performed by the Joint Russian–Mongolian Complex Biological Expedition of the Russian Academy of Sciences and of the Mongolian Academy of Sciences. The prepared database includes spatial data on ecosystems and their anthropogenic disturbance for nine model polygons (at a scale larger than 1 : 200 000) and eight test plots (at a scale of 1 : 5000–1 : 10 000), as well as 1757 geobotanical descriptions made by the authors earlier. The 5.1 GB spatial database is a cartographic web service located at https://mon-exp.nextgis.com/resource/. It is intended for open use on any personal computer, workstation, notebook, tablet, and smartphone with Windows and Android OS, including mobile ones with Internet access.
