Abstract: This paper reviewed the research progress of soil fauna ecology in China cropland ecosystems over the past 30 years, with the focus on the community diversity and geographical distribution of soil fauna, its responses to different tillage modes, cultivation practices (including fertilization and pesticide application), land-use change, and industrial pollution, and its indicative roles in assessing the health state of the cropland ecosystems. The problems in the current related studies in China were pointed out, compared with the researches abroad, and the possible hot issues and perspectives in the future researches of soil fauna in cropland ecosystems were put forward.
