不同程度退化草地土壤成因及特征

Studies on Soil Driving Forces and Characteristics under Different Degraded Degrees in Grassland

从土壤的理化性质、酶活性、微生物及种子库等方面分析了近年来不同程度退化草地的土壤特征,了解草地生态系统受损程度,从而为合理利用土地资源及退化草地生态系统的恢复与重建提供基础资料。

The soil characteristics were summarized under different degraded degrees in grasslands, including soil physical and chemical properties, soil enzyme, soil microorganism, seed bank, etc. The study provided meaningful data for improving grassland management, preventing grassland from degradation, restoring and optimal utilization of degraded grassland as well.
