本论文利用珠海凤凰山典型次生常绿阔叶林下垫面陆气相互作用通量观测塔站资料，对该地区的森林冠层和大气间的能量和碳通量交换特征及参数化进行了初步的研究。本文研究内容主要分为四部分，分别为通量观测资料的必要修正和质量评价、通量和主要气象要素的变化特征、动量和感热交换系数参数化的初步探究以及主要环境因子对碳通量的影响。主要结论如下： （1）湍流原始资料野点需考虑去除；在计算通量数据的过程中各修正过程影响不同，频率响应修正和超声虚温修正对感热通量影响大，WPL修正对碳通量影响大，且修正主要集中在白天，倾斜修正是必要修正。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。 （2）感热通量年变化幅度不大，潜热通量变化显著，尤其在季风后迅速增大。干季感热通量和潜热通量值相当，在湿季潜热通量远大于感热通量。秋冬季相对湿度含量低，随着季风的到来带来大量水汽，相对湿度迅速升高。在干季时，越接近地面相对湿度的垂直梯度越显著，湿季各层相对湿度值均较大，垂直梯度不显著。土壤温度分布遵循冬季随着深度的增加温度逐渐升高，夏季变化相反的规律。干季气温的垂直梯度明显，湿季不显著。风速在冬季变化平缓，且遵循随高度的升高风速增加规律；夏季变化剧烈，低层风速随高度变化梯度明显，高层较紊乱。干季的风向主要为偏东风，到了4月份由于季风爆发，风向主要集中在东南方向和西南方向，9月以后，风向逐渐转回偏东风。 （3）动量交换系数和感热交换系数受大气稳定度的影响，随风速变化显著。动量交换系数和感热交换系数在中性和近中性条件下随冠层表面风速基本不变，在稳定状态下随着风速的增加动量和感交换系数随之增加，在不稳定时变化方向相反。 （4）碳通量变化受森林下垫面呼吸作用和光合作用双重影响，夏季变化幅度大，冬季变化较小。在选取的各环境因子中，光合有效辐射影响白天的碳通量，土壤温度主要影响夜间的碳通量，各层气温中对碳通量影响最大的是地面气温，饱和水汽压差的影响要分情况考虑，不同状态的饱和水气压差会对碳通量产生不同的影响。

The transfer of momentum, heat, and humidity between land and atmosphere determines the stability of the atmosphere to a large extent. Therefore, more and more studies have been conducted on land-atmosphere interactions in recent years. In this paper, based on the research data of the land-atmosphere interaction flux observation tower at Phoenix Mountain, Zhuhai, a preliminary study on the energy exchange between land and gas in this area was conducted to fill the gaps in the study of the forest underlying surface. The research content of this paper is mainly divided into four parts, which are the necessary corrections and quality evaluation of flux observation data, the changes of flux and main meteorological elements, the preliminary exploration of the parameterization of momentum and sensible heat exchange coefficients, and the main environmental factors of carbon connectivity. The amount of influence. The main conclusions are as follows: （1）The turbulent raw data field should be considered for removal；the revision process during calculating flux data affect different, frequency response correction and ultrasonic virtual temperature correction have great influence on sensible heat flux, WPL correction has a large impact on carbon flux and is mainly concentrated in the daytime,the tilt correction is necessary to correct. After the quality evaluation of the observation data, the sensible heat flux is about 85%, and about 80% of the latent heat flux and carbon flux can be used for flux analysis. （2）The change in sensible heat flux during the year is not significant; the latent heat flux changes significantly, especially after the monsoon. The sensible heat flux and latent heat flux are equivalent in the dry season, and the latent heat flux in the wet season is much larger than that in the sensible heat flux. In autumn and winter, the relative humidity content is low. With the arrival of the monsoon, there is a large amount of water vapor, and the relative humidity rises rapidly. In the dry season, the closer the vertical gradient to the relative humidity of the ground, the more significant the relative humidity values of the layers.And The relative humidity values of the layers in the wet season are relatively large, and the vertical gradient is not significant. The soil temperature distribution follows the fact that the temperature increases gradually with the increase of depth in winter, and the summer variation is the opposite. The vertical gradient of air temperature in the dry season is obvious and it is not significant in the wet season. The change of wind speed is gentle in winter, and follows the rule of increasing wind speed with increasing altitude; in summer, the wind speed changes drastically with the gradient of height, and the upper floors are more disordered. The wind direction in the dry season was mainly easterly wind. By April, due to the outbreak of monsoon, the wind direction was mainly concentrated in the southeast and southwest directions. After September, the wind direction gradually shifted back to the easterly wind. （3）Momentum exchange coefficients and sensible heat exchange coefficients are affected by atmospheric stability and vary significantly with wind speed. Momentum exchange coefficient and sensible heat exchange coefficient are basically constant with canopy surface wind speed under neutral and near-neutral conditions. In steady state, the momentum and inductive exchange coefficient increase with the increase of wind speed, and change in contrast during instability. （4）The change of carbon flux was affected by the dual role of forest surface respiration and photosynthesis, with large changes in summer and small changes in winter. Among the selected environmental factors, photosynthetically active radiation affects carbon flux during the day. Soil temperature mainly affects carbon flux at night. The effect of temperature on the carbon flux in the air temperature in each layer is the maximum of surface air temperature. To consider the situation, different states of saturated water pressure difference will have different effects on carbon flux.
