In this paper a genetic algorithm four-dimension data assimilation system was applied to the more complex MM5 model, we verify the performance of the genetic algorithm assimilation system, we take the a heavy rainfall process during 04-05, July, 2003 as the experimental research object, and carry out data assimilation experiment of actual observation data, compare the experimental results of the genetic algorithm assimilation system and MM5 adjoint model assimilation system with the experimental results without assimilation, the following is the result:genetic algorithm assimilation system is used not only in a barotropic primitive equation but also in the complex model, MM5, for example, in the ideal experiment the result of the genetic algorithm assimilation system is better than the MM5 adjoint model assimilation system, in the assimilation experiment of actual observation data, whichever assimilation system is used, the initial field of numerical prediction model is effectively improved and the prediction effect of physical field and rainfall are somewhat enhanced.

本文将遗传算法的四维同化系统运用到更复杂的MM5模式中，在理想实验中验证遗传算法同化系统的性能，并以2003年7月4日"南京暴雨"作为研究对象，进行了实际观测资料的同化，并将遗传算法同化系统和MM5伴随模式同化系统得到的结果跟未同化的结果进行了比较，结果如下：遗传算法同化系统不仅可以用在正压原始方程模式上，同样也可以用在MM5等复杂模式上，理想实验证明了遗传算法同化系统优于MM5伴随同化系统，在实际观测资料同化中，采用两种方法的同化系统都能有效地改善数值预报模式的初始场，能在一定程度上提高物理量场和降水量的预报效果。

In Taiwan area often have typhoon attracting during summer times. Typhoon brings abundant rainfall and the rainfall concentrates to the river, naturally washes out the main channel and the river high alluvion. When flood retreat, the exposed high alluvion can be widely used. Agriculture, plant and wetland, these places can increase zoology. On the other hand ,they baffle current of water flow. So this research focuses on different arrangement of flexible vegetation.

中文摘要因为台湾地区因气候关系常有台风侵袭，台风来临时带来的充沛雨量集中到河川，自然冲刷出主河道和高滩地，当洪水退去时，裸露的高滩地即可以广泛地被利用，有许多的人为开垦、种植，但是这些植生有增加动植物栖地的益处，另一方面也会产生阻碍水流的害处，所以本篇对於不同布置方式的柔性植生做流场的研究。

The model includes that the relationship between median diameter, as well kinetic energy, of raindrop and rainfall intensity obeys logarithmic function, the critical slope degree of soil erosion is 38.4°～43.0° in test area and the best multiple index of rainfall erosivity value is /100. Employing the prediction model, the soil erodibility value, the accelerated value of excavation slope, roadbed slope, construction site, borrow pit, service road and other temporary occupation land and the loss-spoil ration of waste pile were examined. Finally, the integrated soil and water conservation measures in highway construction project have been suggested.

从而建立了凉山州天然降雨雨滴中数直径与雨强的关系和降雨强度与动能的关系，分析了高速公路引起水土流失的侵蚀性降雨标准、侵蚀转折坡度及不同流失区流失量的大小关系，给出了高速公路水土流失预测模式中降雨侵蚀力尺值的最佳复合指标，估算出路堤边坡、路堑开挖边坡、路基、临时施工用地、取土场、便道和其它临时占地的可蚀性K值、加速侵蚀系数A值以及的弃土场的流弃比B值，最后针对高速公路不同防治区水土流失特点提出了相应的综合防治措施。

Using arid area (annual rainfall about 200mm) and dankness area (annual rainfall about 600mm) contrast test, determining the new potato variety's drought resistance, chlorophyll A, B content and CAT activity in the different growth period, study the relation between chlorophyll content, CAT activity and the drought resistance.

采用干旱地区（年降雨量200 mm左右）与阴湿地区（年降雨量600 mm左右）对比试验，测定马铃薯品种生育期的叶绿素a、b含量和CAT活性，研究其与抗旱性关系。

This low carbonate event may have resulted from changes of rainfall. During deglaciation, the dry climate caused a decrease in terrigenous sediment input. However, during Early-Middle Holocene, the rainfall, especially the heavy rain with higher erosions increased rapidly, leading to the increase of terrigenous sedimental supplies from South China mainland and Hainan islands.

在冰消期，出现干旱，陆源物质减少，而早中全新世的雨量，尤其是具较强冲刷能力的大雨量急剧增加，造成北部海南岛和华南陆地的冲刷增强，陆源物质供给增加，从而出现低钙事件。

When evaporation was in process, due to low initial water content, most infiltrated water from small intensity and amount of rainfall would be consumed by intensive evapotranspiration during rainy season, and lateral downslope unsaturated flow seldom took place. However, soil water would move downslope by gravitational and matric potential gradients after continuous rainfall.

3在防止蒸发条件下，再分布过程中，土壤水分在重力的作用下有沿坡向下运移的趋势；在蒸发条件下，由于初始含水量一般较低，雨季量小且分散的降雨极易为强烈的蒸发蒸腾所消耗，侧向沿坡向下流难以发生，但在持续的降雨条件下，土壤水分在重力势和基质势梯度的作用下易沿坡向下运移。

These graupel retained in the cold region gradually grow enough to fall down, which increase the rainfall around the decreasing rainfall center.

这些滞留的霰粒逐渐长大后，落速大于上升运动时下落融化，引起周围地面增雨。

Since the convective cloud system is tilted, and the viewing angle is oblique, the area displacement between ice hydrometeor and the surface rainfall rate makes the relation between Tb and surface rainfall rate is relatively small.

但亮温和地面降水强度之间的相关性较弱，这是由于该对流系统为倾斜的，冰相粒子和地面降水强度之间存在着位置上的不一致，并且观测角为倾斜的。

But Severus escaped the hands of those that Julianus had sent to murder him and sent a letter to the praetorian guard, giving them the signal either to desert Julianus or to kill him.

赛维鲁总算逃过了尤利阿努斯派来的杀手，并写了一封信给罗马的禁卫军，向他们发出信号，要么抛弃尤利阿努斯，要么干掉他。他们立即服从了。
