摘　　要：河道水位的相对稳定对满足河岸带景观需求,保障航运及沿河两岸取水等具有重要意义。基于Flow Event Method（FEM）基本思想,提出了通过识别河道战略点,利用模糊评价进行河道生态水位定值的方法。对广东东江进行生态水位定值,结果表明其关键控制测站岭下站、博罗站的生态水位范围分别为13.71~15.76、1.20~6.44m,其对应流量下限为多年平均流量的51.4%和60.7%,上限为防洪警戒水位对应流量的29.1%和62.7%。实例研究表明该定值方法有较好的适用性。The relatively stable river levels play an important role in meeting the scenery requirements of riparian zones ,maintaining the shipping and water supply .So the study proposes an evaluation method of the ecological river levels by identifying the strategy position and utilizing the fussy assessment based on the basic idea of the Flow Event Method .The study applies the method in Dongjiang River ,Guangdong Province .And the results show that the ecological river level regimes for the scenery of two key hydro‐metric stations ,Linxia Station and Boluo Station ,being 13 .71~15 .76 m and 1 .20~6 .44m ,respectively .And the lower bounds of their corresponding flow regimes amount to 51 .4% and 60 .7% of their average annual flows ,while the upper bounds of them ac‐count for 29 .1% and 62 .7% of the flows corresponding to the warming river level for flood control respectively .The case study has illustrated the applicability of the method .
