| 摘 要： | 在人为或自然因素的作用下， 河道环境常发生频繁的变化， 其变化规律用常规方法很难了解． 而遥感具有宏观、动态、系统研究的优势， 在河道环境研究方面具有可行性． 探讨了河道环境变化的遥感研究方法， 并以东江为例进行了试验性应用研究． 结果表明， 在１９８８～１９９７ 年１０ 年间， 东江中下游河段河道环境具有明显的演变过程， 岸、滩冲淤变化明显， 大部分河床发生严重下切， 部分地区发生淤积

| Abstract: | Environment of riverbed is changed frequently by nature and human beings. And that is difficult to survey the environment with the general methods. In this paper, processing methods of remote sensed information are offered and used to study the changes of the Dongjiang river. Some macroscopic, dynamic and quantitative results show that landscape of channel, banks and sandbars changed violently due to over exploiting sand from 1988 to 1997. |
