Abstract：An index system is put forward to evaluate the reuse suitability of farmland drainage water in arid and semi-arid regions threatened by salinization based on fuzzy pattern recognition model. For each index, the range of standard value for every classification is specified by analyzing the relevant literature and existing technical standards comprehensively. The weight of each index is determined by making use of the analytic hierarchy process(AHP). The index system is applied to assess the reuse suitability of drainage water in five typical farmlands in Yinbei Irrigation District, Ningxia. It is shown that except Qianjin farmland the water reuse suitability in the rest farmland is all at the second grade. Particularly, the index values in the middle and late periods of irrigation are less than those in the early period of irrigation, suggesting the water reuse suitability is better than in the middle and late periods. In the middle and late periods, crops need more irrigation but fresh water is in shortage; further the crops are not sensitive to salt. Thus it is feasible to reuse a certain amount of drainage water for irrigation in those periods.
