| Abstract: | This paper, fi-rstly, discusses the process of passage shortening in the Danji-ang River in recent centuries and its causes from historical geography angle. According to research, it comes to the conclusion that before 1938 the Danjiang passage was 396km(from the river mouth to Shang County), but now, the passage is only 83km (from the river mouth to Shenming). That means the Danjiang River has been shortened to 320km since 1938, about 81% of the passage in history. The causes of passage shortening in the Danjiang River are:1.Because of the distortion,of vegetation, loss of water and erosion of soil are serious and the channel is silted up.2.Because of the development of highways, the shipping unfrequented and the quantity of water transport decreased.3.Because of the construction of irrigating works, flow decreased and results in change of river-bed landforms.Finally, detail discussions are made on the orientation of rational use and the measures of shipping in the Danjiang River. |
