摘要
土壤健康是对于土壤质量总体评价时的一个新概念,侧重于描述土壤质量中易受人类活动影响的部分。因此,了解并掌握土壤健康情况对于改善和保护农田土壤环境质量至关重要。文章以康奈尔健康评价系统确定的12个物理、生物、化学指标为基础,采用多层次模糊综合评价法进行分析,通过等级划分以及分值处理,以期科学全面地对土壤健康状况进行评价,研究方法和结果对于我国土壤环境质量评价有参考意义。
Soil health is a new concept for the overall assessment of soil quality which focuses on the part susceptible to human activities. Therefore, it is important to understand and master the soil health situation for improving and protecting the soil quality in farmland. Based on the twelve physical, biological and chemical indicators identified by the Cornell Health Assessment System, the soil health situation was graded and scored by using multilevel fuzzy comprehensive evaluation method, in hoping to establish a scientific and comprehensive evaluation system on soil health status. This study is of referential significance to the evaluation of soil environmental quality in China.
