The natural prograding rate is p = 1 -, in which a means one salt marshes area in one year and b means the salt marshes area after n years. the prograding rate is rapid if the prograding rate of the tidal flat is fast
潮灘淤長快，則鹽沼的擴展速率也快，海岸鹽沼的自然增長速率與潮灘的年淤長速率呈線性相關（ p = 26 . 282x + 0 . 4865 ） 。 -
The prograding rate of the spartina alterniflora vertical to the coast is slower and the prograding rate parallel to the coast is quicker through it also will be slower when expanding across the tidal creeks
它垂直於海岸的擴展速度較慢，平行於海岸的擴展速度較快，但在越過潮溝擴展時，速度也會變慢。 -
According to the data of seism, mud well logging, well logging, cores and the principles of well correlation, this third - order sequence is divided into three fourth - order sequences ( system tracts ) and nine fifth - order sequences ( parasequence sets ). the lowstand systems tract is formed in the background of forced lake regression, which is consist of. three prograding parasequence sets
根據地震、綜合錄井、測井、巖心等資料，依據井間可對比的原則，研究層段的三級層序劃分為三個四級層序（即體系域）和九個五級層序（即準層序組） 。 -
Moreover, the system tracts in sequence are characterized by dualistic structure, namely transgressive - highstand system tracts, and tst > hst. the parasequences are divided into three types, which is respectively dominated by sandstones, mudstones, and shallowing - upward tidal flat system. and prograding sequence and retrograding sequence are composed of stacking parasequence set
層序中體系域具有二元結構特徵，即海侵?高水位體系域，且tst hst ，準層序類型有三種，分別是以砂巖為主的準層序、以泥巖為主的準層序和以潮坪體系向上變淺的準層序。 -
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
可以通過式子計算新圍海堤外側需要予留的鹽沼面積。式中， m為新圍面積， p為鹽沼增長速度， n為生態恢復周期（等於同一岸段兩次匡圍的時間間隔） 。 -
