alluvions造句

• Some factors affecting the alluvion and erosion of the yellow river delta are given and analyzed, including human activities, global warming and sea level rise, deep structure, deposits in the delta, local climate, some ocean factors such as current, wave, tide
  此外，本文还分析了地质构造、沉积相和沉积物、气象条件、海洋动力、海平面升高、人类活动等因素对黄河三角洲的冲淤演变的影响。
• A statistical model is developed and indicates high correlation between the accretion of modem yellow river delta and the water and sediment discharge of yellow river, and the model shows the necessary water and sediment discharge per year to ensure the equilibrium of alluvion and erosion of yellow river delta
  黄河三角洲净造陆面积与黄河入海水沙量的统计模型说明，黄河三角洲冲淤动态平衡时的黄河入海径流量为71.93亿m~3a，输沙量为1.853亿ta。
• Based on 2m contour of surveyed bathymetry from 1976 to 1999 and mean-high-tidal line distracted from remote sensing images acquired by landsat-5 tm from 1976 to 2000 respectively, quantitative analysis about alluvion and erosion as well as the relationship between accretion of modern yellow river delta and the water and sediment discharge of yellow river is made, and the results indicate the mean-high-tidal level is more effective than 2m contour of the bathymetry . it is found that the accretion of modem yellow river delta is becoming less and less, what's more, erosion is even more than alluvion in some recent years . diaokou promontory has been eroded seriously since yellow river changed its course in1976
  以一般高潮线反映现代黄河三角洲冲淤演变时，从1976年黄河改道清水沟流路入海到2000年，整个黄洞三角洲净造陆201.5km~2，淤积有逐渐变慢的趋势，甚至出现净蚀退的年份；刁口河嘴大量蚀退，蚀退速率开始快速，后来逐渐变慢；清水沟河嘴大量淤积，淤积速率开始迅速，后来逐渐变慢，甚至出现净蚀退；清水沟河嘴南侧到支脉沟一段岸线与刁口河嘴以西到湾湾沟一段岸线基本稳定。
