| 摘 要： | 就刈割对近地表草域生态因子的影响进行研究.结果表明:刈割使地表以上15cm光照度增强、温度升高、空气相对湿度和CO2浓度下降,地表日蒸发量升高,10 cm和30cm地温均升高;温度升高的幅度随层次的下降呈降低趋势,日变化峰值的出现随层次的下降而滞后.

| Abstract: | This paper studied on the effect of mowing on the ecological factors of near-surface grassfield. The results indicated that the illumination, temperature, diurnal evaporation of near-surface 15cm increased after mowing, and the relative air humidity and CO2 concentation decreased, and the soil temperature of 10cm and 30cm increased. The rise of temperature took on decreasing trend with the descending of layer, and the peak of diurnal changes took on lag trend. |
