松花江流域黑龙江省部分总面积249412km~2,占全流域面积49%,属中温带大陆季风区,为春旱、夏涝、秋早霜的农业生产环境.全省重早年分占20%左右.山地丘陵区发育着棕色森林土;漫川漫岗地区发育着黑土、草甸黑钙土;平地发育着草甸黑钙土和草甸土等土壤.根据土壤水分供需平衡分析、结合地形和土壤条件,将旱作农区分为旱作农业区、保墒旱作农业区和补水灌溉农业区等三区,三区的比例为4∶4∶2,反映了黑龙江省松花江流域干旱情况总趋势.
The total area of Heilongjiang Province in the Songhua River Basin is 249412km ~ 2, accounting for 49% of the total basin area, belonging to the temperate continental monsoon region, where agricultural production environment is spring drought, summer flood and autumn morning frost. In the hilly area, brown forest soil is developed, while in the Mangchuan area, black soil and meadow calcareous soil are developed. On the flat land, meadow calcareous soil and meadow soil are developed. According to the balance of soil water supply and demand, The ratio of dry farmland to dry farmland, dry farmland for irrigated soil and irrigated farmland in irrigated area are 4: 4: 2, reflecting the general trend of drought in Songhua River Basin in Heilongjiang Province.
