【摘要】 对合肥市安徽农业大学校园水杉林和蜀山森林公园马尾松林土壤呼吸进行比较研究,揭示了两林分土壤呼吸与气温、地温、土壤含水量等影响因子之间的关系。位于市区的安徽农业大学校园水杉林土壤呼吸速率日均值为0.80～1.59μmol.m-2·s-1,近郊森林公园的马尾松林为0.85～4.49μmol·m-2·s-1;两林分的土壤呼吸存在显著差异(P<0.0001)。更多还原

【Abstract】 In order to reveal the relationships between soil respiration rate and air temperature,soil temperature and moisture,an experiment was conducted to investigate the characteristics of urban soil respiration under Metasequoia glyptostroboides and Pinus massoniana stands growing on university campus and suburban forest park in Hefei,respectively.The result showed that the daily average rates of soil respiration were,respectively,0.80~1.59 and 0.85~4.49 μmol·m-2·s-1 under Metasequoia glyptostroboides and Pinus massoniana stands.There existed significant differences in soil respiration between the two forest stands.更多还原
