Results showed that precipitation could stimulate wetland soil CO2 emission rate(P<0.01), but this phenomenon could not be found in farmland soil.
结果表明：降雨导致湿地土壤CO2释放速率显著增加（P＜0.01），而农田土壤无显著差异。
The temperature sensitivity of soil CO2 efflux in forest ecosystem in China, Q10 value, was estimated. It was 1.5 and much lower than the global averaged value, 2.0.
作为衡量土壤CO2释放对温度敏感性的重要指标，计算了我国森林生态系统土壤CO2释放温度敏感性系数-Q10值，约为1.5，该值显著低于全球平均水平，2.0。
In this paper, the effects of elevated CO2 on soil microbial community structure, soil microflora, soil respiration, soil microbial biomass, and soil enzyme activities were summarized.
本文从土壤微生物群落结构、微生物区系、土壤呼吸、微生物生物量以及土壤酶活性方面对大气高浓度CO2的响应进行了综述。
