| 摘 要： | 在准噶尔盆地南缘利用Li-8100开路式土壤碳通量测量系统观测防护林地和农地土壤呼吸速率,同时观测土壤温湿度及近地面气温,分析温湿度对土壤呼吸速率的影响.结果表明,农地土壤呼吸速率显著高于防护林地(P<0.01);两者土壤呼吸速率日变化和季节变化均表现为单峰曲线,日变化最高值出现在12:00-14:00,防护林地在6月...

| Abstract: | Soil respiration rate under windbreak and cropland in southern Junggar basin were measured with Li-8100,and soil temperature,soil moisture and air temperature above the ground surface were monitored at same time.The effects of temperature and moisture on soil respiration rate were analyzed.Results showed that soil respiration rate of cropland was higher than that of windbreak significantly.Soil respiration rate of diurnal and seasonal changes under two types of land use had a simple peak value,both reached ... |
