摘要：In this study, a methodology to evaluate natural and social pressure, environment sensitivity, andecological stability in a GIS-based approach was developed for the Basrah Province, Iraq. The information used in thisstudy was obtained from two different sources: (i) a soil survey with more than 500 soil samples positioned by GPS toquantitatively assessment land map quality with the method of integrated environmental vulnerability index (EVI)within the study area, and (ii) the environmental information implemented in the Geo-scientific map of the BasrahProvince digitized on an Arc/Info GIS with remote sensed imagery (Landsat TM 1990 and ETM 2003). From thecharacteristics and the causes of ecological vulnerability, we established multi-objective ecological vulnerabilityevaluation index system framework, and a Pressure-State-Respond model is built to evaluate the environmentalvulnerability. The results showed that more than 56.3% of the area has reached high vulnerability level, and nearly 1/5of the area is at a moderate level. The integration of different factors contributing to environmental vulnerability maylead to plan a successful combating. The usage of remote sensing data and GIS proved to be useful in visualizing thesensitivity situation of different degradation parameters.
