Abstract: Soil microorganisms are an essential part of soil ecosystems.With the intensification of the global greenhouse effect, the impact of climate change on rice soil is receiving increasing attention.To elucidate environment effect on the structure and diversity of rice soil microorganisms in different planting areas of Jilin province, China, 60 soil samples from three rice planting areas (Eastern (E), Central (C), and Western (W)) of Jilin province were collected, soil chemical properties, soil enzyme activities, and soil microbial structure and diversity were determined in this study.The results showed that soil pH increased gradually from E (5.5) to W (8.3); OM content in C area (14.9 g/kg) was significantly lower than in E (26.3 g/kg) and W (17.0 g/kg).The soil urease content in E (16.6 mg/g per d) and W (21.0 mg/g per d) was significantly higher than in C (9.8 mg/g per d).pH, accumulation temperature, annual average temperature, and altitude were the main influencing factors for soil fungi; however, pH, AN, and rainfall were the main influencing factors for soil bacteria.Climate factors (accumulation temperature, annual average temperature and rainfall) have important effects on soil microorganisms.Moreover, there is a significant positive correlation between soil fungi and rice yield.Therefore, for the quality of soil microorganisms and rice yield, while paying attention to the impact of human factors on soil microorganisms, we should also pay attention to the effects of climate factors on soil microorganisms.
