摘要： 为了解杭州市耕地土壤有机质状况，笔者利用近期获得的耕地土壤肥力测试数据，统计分析了全市耕地土壤有机质的变化特征。结果表明：杭州全市耕地土壤有机质以中量水平为主，大部分土壤的有机质在20~40 g/kg 之间，约有1/4(27.00%)的土壤有机质偏低。土壤有机质平均含量以水网平原最高，其次为丘陵区和河谷平原区，滨海平原最低。第二次土壤普查以来，全市水田土壤有机质平均含量趋于下降，而旱地土壤有机质含量呈现增加趋势。杭州市耕地土壤有机质区域变异大，高低差异明显；应增加水田土壤有机肥料的投入，防止水田土壤有机质的进一步下降，并重视滨海平原区耕地土壤有机质的提升。

Abstract: In order to understand the status of organic matter in the cultivated soil in Hangzhou, variation characteristics of organic matter content of whole cultivated soil was analyzed using soil test data recently obtained from soil fertility survey. The results showed that the level of organic matter of cultivated soil in Hangzhou was mainly medium, organic matter of most cultivated soil belonged to the level of 20-40 g/kg, and about 1/4 (27.00%) soil had a low level of organic matter. Average content of organic matter followed the order of water net plain > hills and valley plain > coastal plain. Organic matter of paddy soil decreased since the second national soil survey, while the average content of organic matter in upland increased. It was concluded that soil organic matter in Hangzhou varied greatly. Input of organic fertilizers to paddy field should be increased to prevent further decline of soil organic matter, and more attention should be paid to improve organic matter of cultivated soil in the coastal plain.
