Variable General Info
Land-use type ?Comment:Land-use types: forest, built-up, cultivated, grassland, surface water. Based on the logistic regression models, land-use demands, spatial policies, and land-use conversion rules, the CLUE-s sub-model was applied to simulate land-use type changes for the three land-use scenarios for 2010-2025. |
Level of protection from disturbances ?Comment:An additional landscape factor that mitigates the adverse effects of threats to habitats is the level of protection, such as the presence of social or physical boundaries, from disturbances. |
Threat type to habitats ?Comment:Threat type to habitats is a class driver variable that sets constant values for the variables; Relative impact of threats, Maximum distance of impact from habitats, Sensitivity of grassland to threats, Sensitivity of forest to threats, and Sensitivity of cultivated land to threats. Threat types: built-up, cultivated lands, highway, provincial road, county road. |
