Development Of An Indicator Based Revegetation SDSS In Areas Affected By Mining Activities

Establishment and monitoring of revegetation in areas affected by mining activities is quite often a difficult task. The efficiency of the scheme applied can be substantially improved by using simple adequate indicators so that progress and trends can be plotted, elucidated and assessed over time. Sustainable revegetation management indicators should take into account soil quality and area characteristics, as well as social, economic and political aspects. In the present paper an interactive prototype Spatial Decision Support System (SDSS) is presented. The system, based on methodological studies, has been designed to identify and interpret indicators that can be used for the evaluation of revegetation efficiency. It provides a platform for formulating indicators describing biophysical, socio-cultural and economic processes during the entire revegetation period. It integrates modular assessment, database management sub-systems and Geographical Information System (GIS). It is structured in a way that takes into account the project environment, soil quality, land characteristics, data acquisition control, output engines and spatial analysis. The output generates visual quality diagrams and interactive attribute quality maps that elucidate revegetation issues.
