Abstract:
Regarding groundwater as the main clue, the study of assessment method of supergene eco-environmentin wa- tersheds is developing. This paper, taking Tuwei river watershed as an example, circling to the main clue of groundwa- ter, tries to combine fuzzy comprehensive assessment method with fuzzy interactive self-organizing data analysis technique (fuzzy ISODATA)to assess the present state of eco-environmentin the watershed. The assessmentindex system and as- sessment standards are established. The assessment result shows that the overall environment is good. The hilly area covered by sand, the valley area, the river source area and the desert area are key areas for water resources and eco-envi- ronment protection. These results provide the scientific basis to assess the influence of water resources exploitation on eco-environment and the protection of water resources and eco-environment in vulnerable regions. The assessment results coincide well with real conditions in Tuwei river watershed.
