９０年代以来，嘉兴洪涝灾害频发，造成土壤渍害，由此造成的粮食损失至少７．５万ｔ／ａ，约占全市粮食总产的３％。低洼涝渍田和粘闭滞渍田是渍害土壤的主要类型，约占全市低产田总面积的８０％。调查了渍害土壤的范围、分布，对其理化性质、土体发育特征以及渍害的发展趋势也进行了分析，提出了相应的防治对策。 Since the 1990s, floods and floods in Jiaxing have been frequent, resulting in soil pollution. The resulting food loss is at least 75,000 t / a, accounting for about 3% of the city’s total grain output. Low-lying waterlogging and sticky stagnation fields are the main types of soil pollution, accounting for about 80% of the total area of ​​low-yield fields in the city. The scope and distribution of soil were analyzed. The physical and chemical properties, the characteristics of soil development and the trend of development were also analyzed, and the corresponding control measures were put forward.
