黑龙江省红松人工林林分乔木层可加性碳储量模型

【目的】大尺度森林碳储量的估算备受关注,而构建林分乔木层碳储量模型是一种评估森林碳储量快捷且准确的方式。【方法】以黑龙江省(东京城、林口、帽儿山、孟家岗)207块红松人工林样地数据为研究对象,选择聚合法、平差法、分解法作为构建林分碳储量模型的可加性方法,以加权回归来消除碳储量模型的异方差。采用留一交叉验证法(leave-one-out cross validation, LOOCV)对3种可加性方法的碳储量模型进行评价。【结果】基于3种可加性方法林分碳储量模型拟合结果之间存在略微的差异。聚合法的总体预测能力略优于平差法和分解法,具体预测精度排序为聚合法>平差法>分解法。当预测林分总碳储量时,3种可加性方法在不同林分断面积区间的预测能力表现并不一致。【结论】基于聚合法的林分碳储量模型更适合于黑龙江省红松人工林的碳储量预测,但当预测红松人工林的林分总碳储量时,应根据林分断面积区间选择合适的可加性方法。

体外冲击波碎石图像的多分辨滤波技术

体外冲击波碎石（ESWL）图像通常呈现较低的信噪比和对比度。随着临床诊断技术的发展，噪声伪影的衰减技术成为一个重要课题。利用非抽取小波变换可以对图像进行平移不变的多尺度分解，结合均方误差意义上最优的自适应Wiener滤波，在有效去除噪声的同时保持了图像的边缘细节。实验表明，该方法相对于传统方法更适于ESWL图像的降噪问题。

Background current affects the internal wave structure of the northern South China Sea

The internal wave modal equations are solved with the consideration of background currents. Analytical and numerical solutions of some specific examples, including observations in the northern South China Sea （SCS）, are obtained to investigate the effect of back- ground current on internal wave vertical structure. The effects of current shear and curvature on internal wave vertical structure are eval- uated separately. It is found that the phase speed and wave structure are modified by background currents, the current shear has little effect on wave structure, whilst the current curvature could have a strong impact on the wave structure. The extent of the effect by the current curvature on the wave structure depends on the magnitudes of current curvature, relative wave speed, and buoyancy frequency, sometimes the effect by the current curvature may even cause the wave to attenuate severely with depth. A new method to obtain the real eigenfunction with depth in the case that the waves become evanescent is also put forward. It is shown that the residual tidal current in the northern SCS is strong enough to cause the wave to attenuate severely at the uooer laver.     

Effect of surface waves on air-sea momentum flux in high wind conditions for typhoons in the South China Sea

The WAVEWATCH-III wave model is implemented in the South China Sea to investigate the air-sea momentum flux in high wind conditions during 23 passages of typhoon occurred in 2005. The wave model is driven by the reanalyzed surface winds assimilated by several meteorologic data sources. The friction velocity was calculated and the relationships between different air-sea momentum param- eters were studied. The results show that the drag coefficient decreases with the wave age generally and levels off for wind speeds higher than 35 m/s under typhoon wind forcing. The spatial variations of air-sea momentum flux parameters in high wind conditions forced by typhoons are completely different from those at weak wind speeds and significantly depend on the relative position from the typhoon center.
