Role and Existing Indicators of Soil Animals in Assessment of Soil Pollution and Indication Characteristics from Their Tolerence Developed under Stress
土壤动物在污染评价中的作用、现行指标及胁迫环境下的耐受性

Current methods for assessment of soil pollution using soil animals need to be improved or innovated. In this paper, from the aspects of biological characteristics and living habits of soil animal functional groups and their roles in soil nutrient cycling, the application of soil animals to assess soil pollution was reviewed. The current generic bio-indicators and methods for assessment of soil pollution using soil animals involving population characteristics, community structure parameters and ecological region models were introduced. Tolerance of soil animals under pollution stress and its influence on assessment of soil pollution were elucidated. Based on acclimation and adaptation of soil animals, the genetic mechanisms and bio-indicators of animal tolerance to soil pollution were discussed.
