珠海凤凰山陆气相互作用观测塔通量数据的质量控制与评价

针对广东省珠海凤凰山森林生态系统2015年的湍流原始数据，分析了各修正过程对通量的影响。结果表明:野点较多，需要考虑去除；频率响应修正对通量结果影响不大；倾斜修正的影响在3%左右；超声虚温修正对感热通量的影响变化幅度达30%；WPL修正对碳通量结果影响可达25%左右。经过对观测数据的质量评价，感热通量约有85%，潜热通量和碳通量约有80%的数据可用于通量分析。感热通量在1年中的变化幅度不大；潜热通量变化显著，尤其在季风后迅速增大；碳通量变化与森林下垫面密切相关，夏季变化幅度大，冬季变化较小。 

QUALITY CONTROL AND EVALUATION OF FLUX DATA OF OBSERVATION PLATFORM ABOUT LAND-ATMOSPHERE INTERACTION IN ZHUHAI PHOENIX MOUNTAIN

Analyzed the turbulence data of Zhuhai's Phoenix Mountain Forest Ecosytem in 2015 and the the influence of the correction process. The result is that the spike more and need to consider to remove. The process of frequency reponse correction has little effect on the flux effects, the slope correction has a greater impact and the change about 3%. The sonic temperature correction has a great influence on the sensible heat flux, the various range about 30%. And the WPL correction has a great influence, especailly the carbon flux about 25% variation. After evaluating the quality, the sensible heat flux is about 85%, and the latent heat flux and the carbon flux are about 80% better. The change of latent heat flux is not significant, and the latent heat flux increase rapidly after the monsoon. The change of carbon flux is closely related to the underlying surface of the forest, great changes in summer and small changes in winter.
