| 摘 要： | 基于2014、2015年6~9月的太阳辐射和土壤热通量观测资料,分析了湘南旱地土壤热通量变化特征。研究表明,6~9月,旱地土壤热通量季节和月变化都呈逐渐减少趋势;5和10 cm晴天土壤热通量日变化呈单峰曲线,与太阳净辐射日变化趋势一致;5和10 cm土壤日均热通量与太阳日均净辐射量之间存在极显著的线性关系。

| Abstract: | Based on the observation data of solar radiation and soil heat flux from June to September in 2014 and 2015 year, variation characteristics of soil heat flux in southern Hunan upland were analyzed. The results showed that seasonal and moths variation characteristics of soil heat flux showed a trend of decline from June to September in upland. Daily variation of soil heat flux showed a single peak curve in 5 and 10 cm depths. And it had the same trend as daily variation of net so-lar radiation. There was a extremely significant linear relationship between daily average soil heat flux and daily average net solar radiation. |
