| 摘 要： | 对六个不同利用方式的红壤退化试验小区的理化、生物学性质进行了分析,结果表明:随着植被的退化,水土流失加剧,土壤容重增加,孔度减小,结构性变差;从常绿阔叶林→草地→裸露地,有机质、全氮、土壤微生物量及其酶活性也都随之下降,而CEC含量和多酚氧化酶变化却不稳定。

| Abstract: | In this paper, the physical, chemical and biological properties of red soil of six different use patterns are analysed. The results showed that with the degradation of red soil, the soil had higher compaction, smaller total porosity, and lower physical moisture. The content of soil nutrients (such as soil organic matter, total N, available P, soil microbial biomass and so on) decreased with the degradation of red soil, but the value of CEC changed up and down. |
