摘要
土壤健康是农产品安全和人类健康的基础,是一个赋有21世纪新世代气息的新概念。健康土壤学的发展,预示了土壤科学进入了一个新世代。论述了土壤健康这一新概念的内涵;阐明了土壤健康与人类疾病、农产品安全之间存在着密切的相关关系;从土壤动物、微生物、植物和土壤酶生态指示的角度,指出了土壤健康指标应该具有灵敏度高、使用范围广、分析测量方法切实可行等生态特点;综述了国内外土壤健康生态指示的研究现状与发展动态;认为除了继续深入现阶段有关土壤健康的研究外,还应从土壤健康的水力学特征与水生生态过程的角度展开研究,使土壤健康评价系统更完善。
Soil health is a foundation of agricultural product safety and human health, and a new concept endowed with the epoch of 21st century characteristics. Development of health pedology has predicted a new era of soil science. In this paper connotation of soil health was elucidated as a new concept. The close relationship among soil health, human diseases and agricultural product safety was expounded. From the aspect of ecological indicators of soil animals, microorganisms, plants and soil enzymes, it is proposed that soil health indexes should have features with a high degree of ecological sensitivity, a wide range of usage, applicable analysis and measurable method. Current research status and future development of ecological indication of soil health both in China and abroad were summarized. It is also proposed that in addition to further in-depth research into some problems related with soil health, soil health research should also be conducted from the aspect of hydraulics characteristics and aquatic ecological processes in order to make evaluation system of soil health more valuable.
