土壤是陆地农业生态系统的重要组成部分,因而土壤质量或土壤健康成为农业可持续发展的重要内涵。在以往的研究中,人们一直强调以土壤理化特性作为持续性指标,但近期国际上关于土壤生物学参数的研究日渐增多,一些参数作为生物指标已表现出很大的潜力,研究空间不断扩展。对农业生态系统来说,土壤生物指标有可能成为系统稳定性的早期预警和敏感指标。
Soil is an important part of terrestrial agro-ecosystems, so soil quality or soil health has become an important connotation of agricultural sustainable development. In the previous studies, people always emphasized the physical and chemical properties of soil as a continuous indicator. However, there are more and more researches on soil biological parameters in the world recently. Some parameters have shown great potential as biological indicators and the space for research has been expanding. For agro-ecosystems, soil biological indicators are likely to be early warning and sensitive indicators of system stability.
