- 摘要:
- 为了研究典型草原上人为干扰对径流小区土壤呼吸的影响，现以2013年建立在锡林河流域内的径流小区及天然放牧草地为研究对象，用ADC土壤呼吸仪测定不同坡位的土壤呼吸日动态。结果表明：不同坡位的土壤温度和呼吸日动态均呈现明显的单峰曲线，峰值出现在13:00—14:30；不同坡位平均土壤呼吸速率顺序为径流小区坡顶（2.61±0.80）μmol?m-2?s-1>径流小区坡底（1.51±0.32）μmol?m-2?s-1>天然放牧草地坡顶（1.31±0.68）μmol?m-2?s-1>天然放牧草地坡底（0.75±0.25）μmol?m-2?s-1，且差异显著（P<0.05）;单变量模型中指数方程较好的解释了土壤呼吸与土壤温度的关系，R2值分别为0.76、0.78、0.87和0.70，Q10值分别为1.68、1.59、2.17和1.91；土壤温度和水分的线性双变量模型R=a+bT+cW可以更好的表示水热因子对土壤呼吸的影响，R2值可以达到0.82~0.89。
- Abstract:
- Dynamic soil respiration in different slope positions was measured by ADC soil respiration apparatus in runoff plots and natural grazing pasture of Xilin River Basin.The effects of human disturbance on soil respiration in typical steppe runoff plots were studied.The results showed that the diurnal variation of soil respiration and temperature could be expressed as a single peak curve and its highest occurred between 13:00 pm and 14:30 pm.The mean soil respiration rate was significant higher in top position of runoff plots(2.61±0.80)μmol?m-2?s-1 than that in bottom(1.51±0.32)μmol?m-2?s-1,or the top of natural grazing pasture(1.31±0.68)μmol?m-2?s-1 and the bottom position(0.75±0.25)μmol?m-2?s-1.The relationship between soil respiration and soil temperature was well explained by single variable model.The R2 values were 0.76,0.78,0.87 and 0.70,respectively.The Q10 values were 1.68,1.59,2.17 and 1.91,respectively.Two variable model of soil temperature and moisture could better express the influence of water heating factor on soil respiration,R2 value could reach 0.82-0.89,which provided a guiding role for the study of the relationship between soil respiration and soil water thermal factor.
