| 摘 要： | 目的]为全面、准确地掌握淮安市土壤有机质变化规律。方法]应用统计学方法对淮安市27个土壤肥力监测点历年耕层土壤有机质含量进行分析,掌握全市土壤肥力长期定位监测点有机质含量的时空变化。结果]1982~2008年土壤有机质含量平均值大幅上升,增加83.2%,平均年递增2.87%;2009后土壤有机质含量增长放缓并趋于平衡,各类土壤有机质含量提升至最高点后基本稳定于22.1~23.7g/kg之间。结论]该研究可为土壤肥力评价和耕地质量管理提供科学依据。

| Abstract: | Objective ] The research aimed grasp the change law of soil organic matter in Huaian City completely and accurately. Method] Soil organic matter contents in the topsoil of the 27 soil fertility monitoring point were studied with statistical methods. And the main change trend of soil organic matter was monitored. Result ] In 1982 - 2008, the average content of soil organic matter rose significantly, increased by 83.2% and the average annual increase was 2.87%. After 2009, soil organic matter content was in growth and balance. All kinds of soil or- ganic matter content increased to the highest point, and then in basic stability between 22.1 -23.7 g/kg. Conclusion] The research could provide a scientific basis for soil fertility evaluation and management. |
