土壤健康评估指标、框架及程序研究进展

土壤健康已经成为土壤学中的研究热点。对土壤健康进行科学的评估是进行土壤健康管理和实现可持续发展目标的基础。然而,由于土壤具有多种属性和生态服务功能,科学的进行土壤健康评估面临着巨大的挑战。本文回顾了土壤健康概念的发展历程,总结了进行土壤健康评估的物理、化学和生物指标及其表征意义;介绍了目前常用的土壤健康评估框架及其适用性,梳理了土壤健康评估的一般程序,并指出我国未来的土壤健康评估应该关注碳汇指标、生物指标和环境指标。本文旨在为建立符合我国国情的土壤健康评估方法提供借鉴。

The Indicators, Framework and Procedures for Soil Health: A Critical Review

Soil health has become a hot topic in soil science. Scientific assessment of soil health is fundamental to soil management and the achievement of sustainable development goals. Soil health assessment is challenging because of the multiple properties and ecosystem services. In this paper, the development of the concept and the traditional health assessment indicators, including physical, chemical and biological indicators, and their connotation were summarized. Also, the commonly used soil health assessment frameworks and their applicability were introduced while the general procedure of soil health assessment was summarized. This study also pointed out that the future soil health assessment in China should enhance the weight of carbon pool index, biological index and environmental index. Thus, the paper aims to lay a foundation for the establishment of a soil health assessment method that conforms to China"s national conditions.
