土壤质量评价的生物指标及其相关性研究进展

长期的人为破坏及不合理利用使土壤质量受到严重的威胁,寻找土壤质量评价指标已成为土壤生态学的研究热点。而传统的理化指标已难满足评价土壤质量的需要,寻找能够全面反映土壤质量动态变化和判别土壤质量变化的灵敏指标已成为土壤学研究的重要内容。本文对近几年来土壤微生物、土壤酶活性和土壤动物等土壤质量生物学指标及其相关性的研究成果进行了综合评述,以其为土壤的合理利用与保护提供理论依据。

Progress in Study of Biological Indexes of Soil Quality Evaluation and the Analysis of Correlation

Soil quality was in subjected of serious threat because of long-term failure and unreasonable land using. Search for the indexes of soil quality has recently become a research focus. The traditional physicochemical indexes were not meeting the need of soil quality evaluation; therefore, search for the indexes which can reflect the dynamic changes and distinguish the changes of soil quality was becoming important research task. Comprehensive review of soil microorganism, soil enzyme activities, soil animal and their correlations, in order to provide theoretical basis for the reasonable utilization and the protection of cultivated land.
