Tide is the primary dynamic factor in building tidal flat ; it must be affect tidal creek system on mud flat. therefore, based on the raster image of the year of 2000, the thesis has built correlation equations between average tidal ranges and the density of tidal creeks, the ratio of the width of outlet to the length of low tidal shore, the ratio of the area of tidal creek to tidal basin respectively. the result shows that the former is high well - marked correlation ; the two latter are well - marked correlation
潮汐是塑造潮灘的主要動力因素，它必然與淤泥質潮灘上潮溝系統的發育有密切的關系，為此，本文以2000年的衛片作底圖，對潮溝系的密度、溝口寬度占低潮線長度的比值以及潮溝面積與潮盆面積的比值，分別與平均潮差建立了相關關系，結果發現，潮溝系的密度與平均潮差之間存在著高度顯著的相關性，溝口寬度占低潮線長度的比值和潮溝面積與潮盆面積的比值與平均潮差之間存在著顯著的相關性。 -
To capture some of the synoptic features of the landscape, several landscape pattern metrics ( i. e. landscape diversity index, landscape density index, and congregation index et al ) was calculated using the raster version of fragstats
選用景觀多樣性、景觀密度、聚集度等6個景觀參數，用fragstats景觀指數計算軟體進行計算分析，結果表明：景觀多樣性指數和均勻度指數都是沿梯度區呈增大的趨勢。
