三江平原位于黑龙江省东北部,为黑龙江、松花江、乌苏里江汇流的三角地带。总面积108800平方公里,其中平原和低洼地面积为66600平方公里。现有耕地5000多万亩,荒地2000多万亩,为我省重点产粮区和大豆出口基地。但由于三江平原地势低平,土质粘重,没有排水出路,现有耕地洪涝灾害严重,荒地也难开垦。所以三江平原水利建设以防洪、治涝为主,开渠挖河与筑堤是工程
Sanjiang Plain is located in the northeast of Heilongjiang Province, the Heilongjiang, Songhua River, Wusuli River confluence of the delta. The total area of 108,800 square kilometers, of which plains and low-lying area of 66,600 square kilometers.
