摘　　要：针对珠三角网河区感潮河涌的生态流量和生态水位受人类活动和潮汐共同影响的典型特征,选取广州市南沙区2条感潮河涌为案例,分析了不同生态流量计算方法在感潮河涌的适用性,并提出适用于网河区感潮河涌的生态水位计算的水文学方法。结果表明,受水文资料限制,Tennant法、近10年最枯月平均流量法在计算感潮河涌生态流量上的适用性不高,而R2-Cross法更符合感潮河涌实际情况,可作为感潮河涌生态流量计算的推荐方法。利用内河涌实测水位进行感潮河涌生态水位计算的水文学方法,更能反映感潮河涌的闸控特点和生态状况。The ecological discharge and water level of tidal rivers are affected by human activities and tidal in the channel network system of the Pearl River Delta.Taking two tidal rivers in Nansha District of Guangzhou as the study cases,this paper analyzes the applicability of ecological discharge calculation methods in tidal rivers.And a hydrological method suitable for tidal rivers in the channel network system of the Pearl River Delta is put forward to calculate the ecological water level.The results show that due to the limitation of hydrological data,Tennant method and the average flow method of the driest month in nearly 10 years are not suitable for calculating the ecological discharge of tidal rivers,while R2-Cross method is more in line with the actual situation of tidal rivers and can be used as the recommended method for calculating the ecological flow of tidal rivers.The hydrological method of calculating the ecological water level of tidal river using the measured water levels of inner-river can better reflect the sluice-controlled characteristic and ecological situation of tidal rivers.
