tidal creek 中文意思是什麼
tidal creek
解釋
潮溝-
There are five genetic classifications of tidal creeks as follows : tidal creek scoured by the currents of ebb tide ; tidal creek eroded by stream from land ; tidal creek scoured by conflux of rainwater ; new tidal creek formed when the old moving ; tidal creek scoured by the flood
在形成上共分為四種成因類型，即落潮水流沖刷型、陸源水流侵蝕型、雨水匯流型、潮溝遷移殘留型和潮流輻聚侵蝕型。 -
This thesis studies the tidal creek system on the prograding mud flat in jiangsu province based on 16 pieces of mss, tm and spot images from 1973 to 2001, and analyses the growth, genetic classification, evolution and affecting factors of tidal creeks
本文結合1973年至2001年共16張不同時相的衛星影像對江蘇淤長型淤泥質潮灘上的潮溝系統進行了研究，對潮溝的發育、形成、演化和影響因素進行了初步探討。 -
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。 -
The sediment of tidal flat affect tidal creek greatly too, especially affect the development of curve current of tidal creek. on the upper tidal flat, the clay is abundance, and the sediment is much more viscous, so the curve current develops well
灘面沉積物的組成對潮溝的發育也有較大的影響，尤其是潮溝曲流的發育，愈向潮灘的上部，粘土的含量愈多，沉積物的粘結作用也越強，潮溝越易發育曲流。 -
There are four characteristics of the evolution of tidal creek as follows : ( 1 ) in the initial stages, tidal creek develops by continuous eroding trace to the source and depriving of the top of other tidal creeks. ( 2 ) the transverse moving of tidal creek occur mostly in the lower part, the middle part and the outlet take second place, and the upper part is more stability. ( 3 ) the different level branches of tidal creek transform into each other in the whole evolution course
潮溝的演變具有以下特點： （ 1 ）潮溝在形成初期，不斷進行溯源侵蝕和襲奪以擴大集水面積而發展壯大， （ 2 ）潮溝的側向移動主要發生在潮溝的下段，中段和口門次之，上段最為穩定（ 3 ）不同級別的支潮溝之間處在不斷地相互轉化過程之中。 -
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
分析得到了潮灘水動力基本特徵：光灘水位漲潮和落潮時間基本相等，而鹽沼前緣帶水位漲潮時間略短；光灘流速過程線在漲潮初和落潮末出現峰值，呈現「雙峰型」特徵，鹽沼前緣帶則冬、春季節呈現「雙峰型」 ，夏、秋季節落潮峰值消失，鹽沼帶四季呈現單峰特徵，潮溝內過程線為「雙峰型」 ；各測點流向均呈現回轉流特徵，在高水位時流向迅速改變，不存在明顯的憩流。
