- 摘要:
- 利用2010年7月至2011年6月大孔径闪烁仪的观测数据分析了显热通量的变化规律，通过主成分分析和相关性分析，筛选出影响显热通量的主要控制因子，探讨了鹫峰站点复杂下垫面水热通量对环境因子的动态响应。结果表明：（1）鹫峰站点显热通量日变化规律与平坦（或均匀）下垫面相似，即显热通量与天气条件密切相关，具有明显的季节性变化规律。4个典型晴天均有峰值出现，从年初至年末显热通量峰值从中午11：00左右向上午偏移；秋分日显热通量波动最明显，冬至日波动较为平缓；夏至日显热通量值最大，处于波峰期，冬至日显热通量值最小，处于波谷期。（2）土壤温度、土壤含水量、空气温度、下垫面蒸散发、风速、风向以及太阳净辐射是影响显热通量传输的主导因子，且不同典型晴天的主导因子不同。（3）土壤含水量和土壤温度与显热通量具有极显著相关性，受下垫面植被组成复杂，地形起伏大等因素的影响，风向与风速与显热输送也表现出了显著的相关性。研究结果有助于加强对复杂山区显热通量规律的认识。
- Abstract:
- One year LAS(Large Aperture Scintillometers(LAS) and meteorological observed data were employed to investigate sensible heat flux over heterogeneous surface from July 2010 to June 2011. The main impacting factors on sensible heat were selected via principal component analysis and correlation analysis. The results showed that: (1) the sensible heat flux in Jiufeng park was closely related to the weather changes and varied in different seasons which was similar to that over plane surface or uniform terrain. Peak values were observed in all four typical sunny days and it moved to morning from 11 o’clock during a year. The sensible fluctuation was the most obvious in September equinox and winter solstice was the least. The sensible heat was maximum in June solstice and least in winter solstice; (2) the principal component analysis suggested that soil temperature, soil moisture, air temperature, ET, wind speed, wind direction and Rn were the main impact factors while the dominant factors were different in different typical sunny days; (3) soil moisture and soil temperature showed the most significant correlation with H, wind speed and wind direction also expressed significant correlation with H because of the complex vegetation and terrain. The results would be helpful for understanding sensible heat flux in complex mountain areas.
