Description
Summary:The degree of vegetation disturbance is assessed using the ENVISAT MERIS multispectral satellite sensor. The temporal dynamics of the terrestrial ecosystems is analyzed using SPOT VEGETATION multitemporal satellite data. Spatial regression models are developed for approximating the exceedances of background concentration levels of heavy metals and sulfur in various components of terrestrial ecosystems. Degrees of vegetation disturbance and territory pollution are evaluated using a scoring system. Territorial zoning by the degree of vegetation disturbance is carried out. All the procedures have been conducted based on ground surveys of key sites of ground pollution (2001–2004) of the Norilsk Industrial Region and remote sensing data (1998–2004).
