摘要
中国现有农田土壤质量评价指标主要包括物理、化学、生物 3 类,但当前的指标体系还存在诸如对生物指标重视程度不足、部分指标检测方法技术落后、指标之间不成体系等问题.在总结此 3 类常规农田土壤质量评价指标的基础上,着重介绍土壤中微量营养元素、重金属、微塑料、农药等化学类物质的定性与定量以及土壤微生物群落组成等非常规指标的应用,并对土壤分析方法和分析设备的升级和研发、生物传感器技术等领域的研究及其在农田土壤质量评价中的应用进行了展望.此可为中国农田土壤质量评价体系的发展提供参考.
Abstract
The current soil quality evaluation indicators for farm lands in China can be classified into three categories:physical,chemical,biological.However,these indicators have certain limitations,such as insufficient emphasis on biologi-cal indicators,outdated detection methods for some indicators,and lack of integration among these indicators.Based on summarizing these three conventional soil quality evaluation indicators,the paper also focuses on the application of uncon-ventional indicators including the qualitative and quantitative analysis of trace nutrients,heavy metals,microplastics,pes-ticides,as well as the composition of soil microbial communities.It also provides an outlook on the upgrading and devel-opment of soil analysis methods and equipment,research in the field of biosensor technology,and their applications in the evaluation of agricultural soil quality.By summarizing and analyzing the current soil quality evaluation indicators and their development trends in China,the paperprovides reference for the development of farm land soil quality evaluation system in China.
