Successful growth of a tree is the result combined effects biotic and abiotic factors. It important to understand how factors affect changes in forest structure dynamics under environmental fluctuations. In this study, we explored initial size [diameter at breast height (DBH)], neighborhood competition, site condition on growth, based 3-year monitoring rate permanent plot (120 × 80 m) montane Fagus engleriana-Cyclobalanopsis multiervis mixed Mt. Shennongjia, China. We measured DBH increments...
Inland lakes play important roles in water and greenhouse gas cycling the environment. This study aims to test performance of a flux-gradient system for simultaneous measurement fluxes vapor, CO2, CH4 at lake–air interface. The concentration gradients over surface were measured with an analyzer based on wavelength-scanned cavity ring-down spectroscopy technology, eddy diffusivity was sonic anemometer. Results zero-gradient indicate flux precision 4.8 W m–2 0.010 mg s–1 0.029 μg CH4. During...
We tested a multilayered model that simulated half‐hour canopy CO 2 and H O exchange of temperate forest mixed with broadleaved trees Korean pine. The variables input to the for scaling fluxes from leaf included vertical profiles height, thickness, biomass five dominant tree species. diurnal seasonal patterns modeled agreed measured values well during nonstressed periods, while showed overestimation water‐stressed high‐temperature which appeared infrequently in our study site. strong...
Abstract Soil nutrition is a key factor influencing species composition in community, but it has clearly scale‐dependent heterogeneity. In the present study, geostatistics methods and canonical correspondence analysis (CCA) were used to detect: (i) variation range of soil spatial heterogeneity; (ii) influence topographic factors on distribution nutrition; (iii) relationships between chemical properties community. all, 23 variables measured, including total N organic C, Al, Ba, Ca, Cr, Cu,...

Since the new century, Association of Southeast Asian Nations (ASEAN) has managed to sustain stable economic growth, drawing global attention due its robust performance. Nighttime light (NTL) observations have been recognized as a useful tool for monitoring long-term socioeconomic development trends over large areas. Therefore, this study focused on analyzing spatial and temporal distribution NTL data in ASEAN countries from 2000 2022. The results reveal that is closely correlated with four...
作为冷季主要的天气事件，冷空气过境会改变湖泊上方的气团性质，对湖泊的水热通量产生影响，进而影响湖泊的生物物理和化学过程.以亚热带大型浅水湖泊——太湖为研究对象，基于2012-2017年5个冷季（11月-翌年3月）的太湖中尺度通量网观测数据，量化不同强度冷空气（寒潮、强冷空气和较强冷空气）对太湖水热通量的影响.结果表明：在5个冷季中，寒潮、强冷空气和较强冷空气发生的总次数分别为4、11和33次，累积持续天数分别为14、31和78天.冷空气过境显著增强太湖的水热通量，3种冷空气过境使太湖的感热通量分别增至无冷空气时的10.3、6.0和4.3倍，潜热通量分别增至无冷空气时的4.0、2.1和2.7倍.虽然冷空气影响天数仅占冷季天数的16.4%，但对整个冷季的潜热和感热通量贡献分别为34.9%和51.7%，以较强冷空气贡献最大.冷空气影响时，水-气界面的温度梯度是太湖感热通量的主控因子，而潜热通量的主控因子为风速.与深水湖泊相比，太湖等浅水湖泊对冷空气过境的响应更快，寒潮过境时尤为明显.;As the major synoptic system, cold air events...
定量研究城市区域人为CO2通量对于控制温室气体排放具有重要意义，而基于大气CO2浓度观测与大气传输模型方法反演区域尺度的CO2通量是未来的一个重要发展方向，其中模型对大气CO2浓度的模拟则是能否成功反演CO2通量的重要基础，然而我国还未有针对城市区域CO2浓度的长时间（＞1年）模拟.本研究基于高空间分辨率的人为源CO2资料与拉格朗日大气传输模型（WRF-STILT），对南京市郊区34 m观测高度处2014年大气CO2浓度进行模拟，并就模型模拟结果的主要影响因素和源贡献组成进行了分析，研究得出以下结论：① WRF-STILT模型能较好模拟出4个季节观测到的高CO2浓度及有季节差异性的日变化特征.② 观测CO2浓度的足迹贡献源区（footprint）的季节变化在盛行风向影响下差异巨大，CO2浓度增加值在前1 d的主要贡献占据总浓度贡献的90%，表明该34 m高度观测点可代表长三角区域的CO2排放量的影响，而安徽东部和江苏中南部对其影响更大；③ 相对于排放源的日变化，边界层高度等气象因素的差异是引起CO2强日变化的主要因素，这也是模拟的各季度浓度增加值差异的原因，其中秋季（34.97...
