| 1. | So the tidal creeks must be managed in order to recover the salt marshes
为了恢复盐沼，必须对这些潮沟进行整治。 |
| 2. | In some coast , the revolution of salt marshes are influenced by the moving of the tidal creeks , especially that parallel to the salt marsh edge would move landward , which will make the salt marshes eroded
在某些岸段，盐沼受潮沟运移的影响，尤其是平行于盐沼外缘的潮沟向岸摆动，将侵蚀盐沼草滩。 |
| 3. | 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
它垂直于海岸的扩展速度较慢，平行于海岸的扩展速度较快，但在越过潮沟扩展时，速度也会变慢。 |
| 4. | 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
在形成上共分为四种成因类型，即落潮水流冲刷型、陆源水流侵蚀型、雨水汇流型、潮沟迁移残留型和潮流辐聚侵蚀型。 |
| 5. | 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
滩面沉积物的组成对潮沟的发育也有较大的影响，尤其是潮沟曲流的发育，愈向潮滩的上部，粘土的含量愈多，沉积物的粘结作用也越强，潮沟越易发育曲流。 |
| 6. | 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
本文结合1973年至2001年共16张不同时相的卫星影像对江苏淤长型淤泥质潮滩上的潮沟系统进行了研究，对潮沟的发育、形成、演化和影响因素进行了初步探讨。 |
| 7. | 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
潮汐是塑造潮滩的主要动力因素，它必然与淤泥质潮滩上潮沟系统的发育有密切的关系，为此，本文以2000年的卫片作底图，对潮沟系的密度、沟口宽度占低潮线长度的比值以及潮沟面积与潮盆面积的比值，分别与平均潮差建立了相关关系，结果发现，潮沟系的密度与平均潮差之间存在着高度显著的相关性，沟口宽度占低潮线长度的比值和潮沟面积与潮盆面积的比值与平均潮差之间存在着显著的相关性。 |
| 8. | 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。 |
| 9. | 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
潮沟的演变具有以下特点： ( 1 )潮沟在形成初期，不断进行溯源侵蚀和袭夺以扩大集水面积而发展壮大， ( 2 )潮沟的侧向移动主要发生在潮沟的下段，中段和口门次之，上段最为稳定( 3 )不同级别的支潮沟之间处在不断地相互转化过程之中。 |
