To explore soil respiration and impact factors under different green plants in Zhengzhou City by IRGA, taking four green plants (Albizzia julibrissin, Sophora pendula, Prunus cerasifera and Chaenomeles speciosa) as experimental materials, we investigated the soil nutrients, soil enzyme activities (0—10 cm) and other environmental factors, and used exponential model to analyze the relations between soil respiration and soil temperature and humidity, to provide the scientific basis for the ecological landscape configuration, and to choose suitable greening plants and urban greening construction. The results showed that: (1) the daily air temperature showed a single peak curve, and daily atmospheric moisture had a variation trend of ‘V’ shape, soil temperature at 0—10 cm depth had a same variation trend with atmospheric temperature, which the peak occurred at 14:00, and soil moisture had a variation trend of ‘V’ shape with the local fluctuation; (2) the daily soil respiration rate showed a single peak curve, and the daily maximum of soil respiration rate occurred at 14:00 and the minimum of soil respiration rate occurred at 6:00, and at same time in a day, the soil respiration rates decreased in the order: Albizzia julibrissin > Sophora pendula > Prunus cerasifera > Chaenomeles speciosa; (3) it was found that soil respiration was extremely significantly correlated with soil temperature and soil moisture content, thier relation could be described by exponential equation (p < 0.05); (4) the soil nutrients and soil enzyme activities under these four green plants decreased in the sequence: Albizzia julibrissin > Sophora pendula > Prunus cerasifera > Chaenomeles speciosa, while the total soil phosphorus had no difference under these four green plants (p > 0.05); (5) through the partial correlation analysis to exclude other environment factors, we found that soil respiration had a correlation with soil nutrients and soil enzyme activities to some degree, and the correlation coefficient under Albizzia julibrissin and Sophora pendula were higher than those under Prunus cerasifera and Chaenomeles speciosa.
