Sun Cai · 2000
The development of ground water vulnerability concept is such a continuously enriched, perfected and developed course which is from simple to complex, from considering inner factors merely to considering inner and out factors comprehensively, and from divergence to agreement. Correspondingly, methods of assessment are from qualitative description by using maps to quantitative express by using methematical model. In this paper, some existed problems of ground water vulnerability assessment are put forward, and the present situation of research is discussed, and this paper points out that it is a hopeful research direction to assess the ground water vulnerability by using gray system theory, fuzzy methematical theory, AHP and GIS techniques.
