M atter elem ent analysis is adop ted to comp rehensive assessm ent. T he assessm ent results indicate that it is feasible to app ly m atter elem ent analysis to comp rehensive assessm ent on developm ent and utilization of w ater resources and that X ian is at developm ent stage of w ater resources developm ent and utilization w ith great po tential. T he assessm ent results are generally consistent w ith tho se obtained by attribute recognition m ethod and fuzzy comp rehensive evaluation m ethod.
