东北黑土区土壤动物对玉米秸秆不同还田方式的响应

秸秆还田是保护东北农田生态系统黑土资源重要的农业管理手段，在应对黑土退化问题上发挥了重要作用。土壤动物是评价农田生态系统质量和土壤环境优劣的重要指标。为深入分析不同秸秆还田方式对东北黑土区农田中土壤动物群落的影响以及对于土壤环境的改良状况，本文综述秸秆直接还田与秸秆间接还田方式下的土壤动物群落组成、多样性以及动态分布特征，总结概括不同还田方式下土壤动物群落特征差异的影响因素。基于目前秸秆还田与土壤动物相关研究过程中存在的问题进行展望，为秸秆还田模式下东北地区的黑土资源保护与农业生态可持续发展提供参考。

Responses of Soil Fauna to Different Returning Methods of Maize Straw in Mollisol Area of Northeast China

Straw returning is an important agricultural management method to protect mollisol resources in the agricultural ecosystems of Northeast China, and plays an important role in coping with mollisol degradation. Soil fauna is an important indicator for evaluating the quality of farmland ecosystem and soil environment. In order to deeply analyze the effects of different straw return methods on soil fauna in farmland in the mollisol area of Northeast China and the improvement of soil environment, this paper reviews the composition, diversity and dynamic distribution characteristics of soil fauna under direct straw return and indirect straw return; the influencing factors of soil fauna characteristics under different return methods are also summarized. Finally, based on the existing problems in the current research process of straw returning to the field and soil fauna, this paper expected to provide a scientific basis for the protection of mollisol resources and the sustainable development of agro-ecology in Northeast China under the mode of straw returning to the field.
