The different points of views, transverse section, plane and volume changes are considered. The results show that the evolution of the Xinqiao Channel has experienced three stages: in 1861~1926 ,the Xinqiao Channel area had been eroded at first and then silted; the Xinqiao Channel is formed during 1926~1958 with the channel experiencing persistence erosion; from 1958 to 2002, the total volume of the Xinqiao Channel keeps stable with the volume of 5.02×108m^3. The pattern of 10m contour has shaped to a certainty in 1926 and 5m contour of the upper and lower parts of Biandansha has been joined. The change of sections of the Xinqiao Channel reflects its thalweg movement to the North Bank 1.1~2.8 km, its shape changes from "U" shape to "V" shape and its depth has been deepened.

计算结果显示在所研究的区域内自1861年以来新桥水道冲淤过程明显被分为三个阶段：1861~1926年的66a间新桥水道区域经过一段时间的冲刷后又重新产生淤积，总容积变化不大；1926~1958年的33a间新桥水道在不断的冲刷中总容积由2.603亿立方公尺增长到5.076亿立方公尺；1958年至今的45a时间里水道容积基本保持在平均5.02亿立方公尺。1926年新桥水道10m等深线已经形成一定的格局，1947年5m等深线向上延伸，扁担沙已经不再与崇明岛相连；1958年上下扁担沙的5m等深线基本连成一体，可以认为此时新桥水道已经形成。

Based on the above-mentioned parameter, according to the relationship between robust estimation and nonlinear diffusion, the Turkey loss function is introduced as the diffusion function in SAR image decomposition because of its better performance, and the contour of an image is extracted by the Turkey diffusion function with the proposed diffusion parameter mentioned above. The experiment results indicate that the Turkey loss function based diffusion process can strengthen the conspicuous contour. Additionally, a Raita\'s criterion-based method, solving the automatic diffusion threshold, is proposed to automatically set the threshold in diffusion decomposition.

针对基于梯度参数和局域方差系数的扩散在对SAR图像进行分解时存在的缺陷，提出了一种局域方差系数与窗口幅度均值积的扩散系数，该系数能够更有效地实现潜在目标区域和背景区域的区分；在此基础上，根据鲁棒估计与非线性扩散的联系，引入扩散效果更好的Turkey损失函数作为图像分解中的扩散函数，并结合局域方差系数与窗口幅度均值积的扩散参数来提取图像的轮廓，结果表明：基于Turkey损失函数的扩散过程对特征突出的边缘所起的&强化作用&更加明显；此外，针对扩散分解中的阈值确定问题，提出了一种基于拉依达准则的扩散阈值自动求解方法，实现了扩散阈值的自动求解。
