本文提出黄河下游悬河决溢风险的影响因素应当包含水沙运动、区域地壳稳定性、河势演变和堤防稳定性4个方面，并据此建立了指标体系和基于GIS技术的多层次模糊综合评判模型，对不同洪水情景下黄河下游的决溢风险进行了评价。

The reaches of greater dike breach risk mainly distribute in wandering reaches.(4) The dike breach risk of the south bank is relative higher in wandering reaches.(5)The dike breach risk of the north bank is higher than the south bank in winding reaches. Simultaneously, the evaluation results manifest that the evaluation indexes system established from the locomotion of incoming water and sediment load, the regional crustal stability, the evolvement of river regime and the stability of river dikes, can reflect the actual situation of hang river in the lower Yellow River more fully. The application of multi-hierarchical fuzzy

评价结果同时表明，从水沙运动、区域地壳稳定性、河势演变和堤防稳定性4个方面建立评价指标体系，能够更加全面的反映黄河下游悬河的实际情况；运用多层次模糊综合评判法能够较好地解决影响因素众多、作用机制复杂的悬河决溢风险问题；运用GIS技术强大的空间分析功能，使黄河下游悬河不同空间位置的决溢风险得到了量化，可以客观地反映黄河下游河道不同空间位置决溢风险的差别，对于指导防洪和河道治理的实践具有重要的现实意义。

Stockell kept a diary. He recorded that he came in below Vierville, that the skipper of the LCI feared the underwater beach obstacles mines and thus forced him to off in chest-deep water, that he saw equipment littering the beach, and then "The first dead American I see are two GIs, one with both feet blown off, arms wrapped about each other in a comradely death embrace."

斯托克保留着一本日记，日记记录了，当来至维尔维村下方时，LCI舵手担心水下滩头障碍雷，强令他离船，下到齐胸深水里，斯托克看到滩头零乱丢弃的装备，以及&我见到的第一批阵亡美军——两个大兵；样子是两脚肿胀，双臂亲密环抱对方的死亡拥抱。&

But I've had a couple of GIs write to say that this colonel or that general made it to the front lines in their sector.

Combined GIS with MATLAB, the automatic extraction of RS and geography information of sample plots was realized.5. Introduced the resist-PCA estimation method to build the estimation formula on crown density, stock volume and diameter breast height, good forecast accuracy was achieved and the deficiency of traditional LMS parameter estimation was made up.6. The estimation process software of the model was developed, including data pretreatment, weight function selection, LMS estimation, PCS estimation, resist-PCA estimation, accuracy assessment and other function models, in order to c

摘要4、结合Gls和MATLAB技术实现对样地遥感信息和地理环境信息的自动提取。5、引入抗差主成分估计方法建立郁闭度、蓄积量、胸径的估测方程，取得了良好的估测精度，弥补了传统最小二乘参数估计的不足。6、开发了模型估测处理软件，包括数据预处理、权函数选择，LS估计，主成分估计、抗差主成分估计、精度评价等模块，实现数据处理、模型研建与精度评价的自动化、一体化。
