不同利用类型土壤生化作用强度与土壤退化程度分析

摘要

通过对研究区6种不同利用类型土壤生化作用强度的定量研究，探讨土壤生化作用强度与土壤退化程度的关系及土壤退化的内在原因，旨为退化土壤生态系统的恢复与重建提供科学依据。研究表明：不同利用类型对土壤生化作用的影响都达到了显著影响水平，不同利用类型土壤生化作用强度存在明显差异，土壤生化作用之间的相关性与生化作用强度一样可表征不同利用类型的土壤退化程度。%This paper studied on the correlations of soil biochemical and soil degeneration under six different soil-utilization in study area. Through the quantitative research on soil biochemical intensity we found the internal cause of soil degeneration. The aim was to provide scientific basis on restoration and rehabilitation of degraded soil ecosystem. The results showed that： the different use types on soil biochemical effects was significant influence soil biochemical activities were different under differ ent utilization types, the correlations among soil biochemical activities and soil biochemical intensity could indicate the soil de generation degree under different utilization types.
