干旱半干旱地区农田生态系统中土壤动物研究进展

Research Progress of Soil Fauna in Arid and Semi-Arid Farmland Ecosystems in China

干旱半干旱地区是我国的农业后备战略基地,近年来受土壤风蚀及土地荒漠化影响的农田面积越来越多。土壤动物在农田生态系统中具有特殊功能与作用,对土壤发育和提高土壤生产能力具有重要意义。文章综述了国内干旱半干旱地区农田生态系统中各种影响因子对土壤动物的作用,并对目前存在的问题和未来的展望进行了评述。

Arid and semi-arid areas are the reserve strategic bases for agriculture in China.In recent years,more and more farmland areas are affected by soil wind erosion and desertification.Soil fauna have special functions in the farmland ecosystems and have important significances for soil development and soil productivity improvement.In this paper,the effects of various factors on soil fauna in arid and semi-arid farmland ecosystems in China were reviewed,and the existing problems and prospects for the future were reviewed.
