Functional Analysis of Landscape Structure for Land Use Planning in Basin Geosystems of Central Yakutia (the Erkeeni Valley is an Example)

Abstract

The purpose is to study the landscape structure of the Erkeeni valley basin in Central Yakutia by methods of geoinformation mapping and functional analysis from the perspective of genetic-morphological and fl ow organisation. Materials and methods. The landscape map of the catchment area was compiled using multi-temporal Sentinel 2 images of ASTER GDEM digital elevation model based on the functional-dynamic approach using time series of spectral indices on the Google Earth Engine platform. Results and Discussion. We determined the socio-economic and ecological functions of typical and rare landscapes to develop the guidelines for land use planning. Six paradynamic complexes (PCs) were identifi ed to determine the fl ow organization of landscapes by hydrographic networks. Considering the diff erences in landscape structure of each basin PC and determined priorities in land use, we developed recommendations for spatial decision-making. Conclusions. The landscape structure of the basin allows for agricultural land use to utilise the potential for increasing distant arable land at the expense of typical larch forests. In the valley part, priority should be given to pasture and tourist-recreational land use.
