ECOSYSTEM HEALTH ASSESSMENT IN INNER MONGOLIA REGION BASED ON REMOTE SENSING AND GIS
Ecosystem health is an important index of the regional sustainable development. In view of the singularity of indicator selection caused by the limited application of remote sensing and GIS at present, this paper took the Pressure-State-Response (PSR) model as reference, and revised the model in multi-analysis foundation. The pressure, vigor, organization structure, response and resilience were selected as the indicators of ecosystem health. This study distilled the vegetation index, image interpretation, change detection by remote sensing and GIS. The comprehensive assessment factors were developed with the integration of the social economic and demographic data, and some concepts of landscape ecology were introduced in this process. Finally, we analyzed the ecosystem health in Ordos area through ecosystem structure analysis, human footprint effect analysis, response analysis, resilience analysis, indicators extraction and system health assessment.
