摘　　要：基于海河河口盐度与径流关系、盐度与生物生长的相关分析,建立了入海径流与盐度的线性回归方程,计算了天津市最低入海水量需求,并从保护近海生物多样性及生态系统完整性角度分析了淡水入海最佳月份,计算了最低入海生态需水量。To reasonably control the estuary ecosystem structure, protect the water quality and realize the sustainable utilization of sea resources, we discussed the lowest amount of sea outflow from Tianjin city to the Bo Sea, and calculated a fresh water demand between April and June for the purpose of protecting coastal biodiversity and restoring the sea area ecosystem. The results show that a minimum annual ecological need amount of sea outflow of 1.32 billion m^3 should be guaranteed and 0.2 billion m^3 fresh water between April and June is let off.
