| 摘 要： | 赣江下游河道在历史上曾发生过多次改道变迁。每次变迁都会改变原有的生态环境．因此了解和认识古河道的变迁，对生态环境的治理将会带来一定的帮助。对赣江下游历史上的几次河道变迁扣近期的河道演变作了较为详细的研究，认为其演变主要表现在河道洲滩冲淤的交替、河流走势以及主汉易位等，总体趋势是淤大于冲，且趋于加剧。因此，出现多数洲滩淤胀扩大扣淤积合并扩大，河槽变窄、河床变浅等现象；河道变迁对环境的影响主要表现在河道淤塞、河床抬高，引起洪水位上涨，对两岸人民生命财产造成严重威胁。

| Abstract: | Gan River lower reaches Stream was divagated and transited several times in history. The ecological environment is altered after every transition. So knowing and understanding the old channel transition have some assist to father the ecological environment. The paper researches particularly the Gan River lower reaches stream transition, considers the evolution expresses chiefly in replacement of stream beach scour-and-fill and stream tendency and main fork translocation etc. The collectivity tendency is slugging greater than clash, driver to aggravate. The majority beach enlarges and mud filling merges and channel narrows down and bed River shallows etc. The influence to environment expresses chiefly in stream silting and bed River elevating and flood stage rising and threatening life property of people two bank. |
