土壤健康的评价方法及应用

Assessment methods of soil health and their applications

  • 摘要: 健康的土壤是作物生长、绿色农业和文明永续发展的基础,合理评价土壤健康也是精准农业和再生农业的必然要求。当前,针对土壤健康评价及敏感指标的筛选,已有大量研究;但不同土壤健康评价方法的适用性及其优劣仍不明晰,如何敏感而准确地评估土壤健康状况亟待解决。本文在厘清土壤质量和土壤健康内涵的基础上,评述了国内外主流土壤健康评价方法的指标体系、优缺点、应用状况及局限性,从重视高强度人为利用土壤(水稻土、城市绿地、矿山开采地和保护地土壤)健康状况评价,加强开发和优化基于土壤生物学指标的土壤健康评价工具和开发适应不同空间尺度的土壤健康评价工具三个方面进行了展望。

     

    Abstract: Healthy soil is the foundation for crop growth, green agriculture, and sustainable development of civilization. Reasonable evaluation of soil health is an inevitable requirement for precision agriculture and regenerative agriculture. Soil health evaluation and screening of sensitive indicators have been conducted; however, the adaptability, pros and cons of different soil health evaluation methods remain unclear. How to assess soil health sensitively and accurately needs to be solved. Therefore, based on clarifying the connotation of soil quality and soil health, this paper reviews the index structure, pros and cons and application limitations of major soil health evaluation methods. Three priorities in soil health study field are proposed. The health status evaluation of high-intensity anthropogenic soil (rice paddy, urban green space, mining land, and greenhouse) shall be received much more attention. Soil health assessment based on soil biological indicators needs to be optimized. Novel soil health assessment method adapted to different spatial scales is also needed.
