salt marsh造句

• After analyzing , the author got the basic character of tidal flat hydrodynamic : the time of flooding on bare flat and ebbing is basically the same and the time of flooding on pioneer zone of salt marsh is a little short ; the process curve of current speed on bare flat did not appear peak value on the beginning of flooding and at the end of ebbing but presented double peak , that is , it presented double peak in winter and spring and ebbing peak value disappeared in summer and autumn , salt marsh presented single peak character in a year and the process curve in tidal creek presented double peak ; all current direction on every spot presented gyration current and the current speed changed rapidly during the high water level without obvious slack water period
  分析得到了潮滩水动力基本特征：光滩水位涨潮和落潮时间基本相等，而盐沼前缘带水位涨潮时间略短；光滩流速过程线在涨潮初和落潮末出现峰值，呈现“双峰型”特征，盐沼前缘带则冬、春季节呈现“双峰型” ，夏、秋季节落潮峰值消失，盐沼带四季呈现单峰特征，潮沟内过程线为“双峰型” ；各测点流向均呈现回转流特征，在高水位时流向迅速改变，不存在明显的憩流。
• A formula of n = can be used to calculate the residual salt marsh area outside the seawall when reclaiming , in which m means the new reclaiming area of the salt marsh , p means the prograding rate of the salt marsh , n means the ecology recovering period which is equal to the interval between two reclaiming along the same coast
  可以通过式子计算新围海堤外侧需要予留的盐沼面积。式中， m为新围面积， p为盐沼增长速度， n为生态恢复周期(等于同一岸段两次匡围的时间间隔) 。
