In t his pa2 per, the concept of w ater resources car ry ing capacity ( WRCC) based on the w ater resources sy st em health was pr oposed, and the co rr esponding index sy stem and evaluat ion standard fo r the r eg io nal WRCC w ere developed. In addition, the combination weigh2 ting approach w as established to evaluate the WRCC based on the decision making functio n in analytic hierar chy pro cess ( AH P) and the adv antag e of objective standard reflected by the maximum dev iation metho d. The set pair analy sis mo del was dev eloped based on the confidence rule and scor ing rule o f att ribute recog nition theor y, and it was applied to analyze the WRCC in Datong of Shanx i Prov ince. The r esults show ed that the WRCC indicato r va ries between 0. 499 and 0. 728 from 2005 to 2012; the WRCC of Dato ng incr eases annually w ith the pr omotion o f water2saving cit y const ruct ion and gr een economic dev elo pment; and the w ater r esources sy stem is in sub2health status, so the measures of w ater resources manag ement, water envir onment pr otec2 tion, and w ater po llution co nt ro l should be taken to impro ve the wat er resour ces system health.
