Mapping of environmental niches of plant communities by gis means (on an example of pine and poplar forests of republic Tyva)
On fields of district a diversity forest-vegetation conditions is defined by a combination of values of heat and moisture. On curves of laws of physics environmental niches are formed. In limens geomorphologically homogeneous terrain environmental niches are decoded on structural landforms. As the basic geomorphologic indexes - the absolute height, a bevel, and an exposition - have dimension for mapping of environmental niches there is a possibility of use digital terrain model, DTM. Thus divisibility planimetric deciphering becomes preliminarily set, i.e. corresponding to objects in view. In work the procedure of mapping is stated by GIS means and results of its application are shown.
