沙蜂

Others were desert creatures, like the Sand Wasp that flittered around a little ways off while launching volleys of baby wasps at me.

其他的则是一些沙漠生物，如一直在盘旋的并向我发射幼蜂的沙蜂。

Within a single storm, process of runoff and sediment seem the same in outsets of different scale watersheds, about runoff rate is 1.27 m/s, concentration of sediment tend to change little and nearly 700 kg/m~3, this determine the relationship between water and sediment, or the relation reflect study area situation, for example, soil and event storm and sediment and so on. In fact this program established scale transition partly.(2)The loess plateau in north china is located in the middle yellow river basin, and records some of the highest erosion rates in the world. The hilly part of the loess plateau is one of the most severely eroded regions of the loess plateau.

基于此本论文选择陕北大理河流域为对象，依据黄河支流的水文资料，分析了不同尺度大小流域的水沙侵蚀资料，取得以下结果：(1)发现就次暴雨洪水而言，各尺度流域出口的径流泥沙过程都表现为洪峰陡涨陡落沙蜂陡涨缓落，含沙量随流量增大到一定程度1.27m／s时变化趋于稳定，保持在400kg／m~3以上，决定了该地区水沙之间的关系，不同尺度大小流域出口暴雨洪水的水沙关系在一定程度上是一个区域特征值。
