Abstract
Drainage density or landscape fragmentation is the ratio of slope length (measured in m) and unit area (measured in km ²) and expresses the horizontal fragmentation of the landscape. In the study presented in this article refers to the area for the three administrative units studied: Savadisla ATU, Ciurila ATU and Floresti ATU. Creating GIS spatial analysis model required the following steps: creating the database, appropriate spatial modeling, model validation to quantify the risk. Spatial analysis is based only on morphometric characteristics of the territory, which are derived from digital elevation model (DEM). Each element of morphometric database we included spatial analysis model parameter identification probability of landslides.
