黑土退化阶段与强度分析

Analysis on the Retrogressive Stages and Intensity of Terra Near

综合分析了黑土退化的影响因素,黑土退化的主要驱动因子是土壤有机碳的变化,有机碳的变异过程直接影响到土壤各要素的变化。利用新的方法进行分析,提出黑龙江省黑土退化发展的阶段和退化的强度。

The factors on terra hera retrogression were comprehensively analyzed in this paper. The main reason causing terra hera retrogression is the organic carbon variation, the variance progress of organic carbon directly affect each element change in the soil. The development stages and retrogressive intensity of terra hera in Heilongjiang were put forward, analyzed by the new method.
