摘  要:
采用红外气体(IRGA)法对华北土石山区植物群落土壤呼吸速率、土壤温度和湿度进行测定。结果表明,土壤呼吸速率日变化呈单峰曲线,最大值在15:00左右,最低值在日出前后;季节变化比较明显,土壤呼吸速率夏季最高,冬季最低;呼吸速率大小受群落类型、土壤温度、土壤湿度等因子影响。

摘  要:
Soil respiration of typical plant communities of earth-rock mountain region in Northern China was studied with IRGA.The results showed that the diurnal dynamic of soil respiration appeared as a single peaked curve with the peak presenting at about 15:00.The highest value of soil respiration was in summer,while the lowest was in winter.Community types,soil temperature and soil humidity were the main factors affecting the soil respiration.
