摘要
江西连年来发生水患灾害 ,在全国属较为严重的省份之一。在每年汛期 (4~ 8月 )为水患灾害发生的高峰期。长江中游江西江段是江西防洪的主要地带 ,近年来由于该段防洪干堤经第一、第二期修堤工程 ,坝体稳固。虽然 1998年、1999年长江大水没有造成溃堤 ,但潜在的水患地质灾害仍是非常严重。作者通过对野外实地进行调查、访问 。
The flood catastrophe in Jiangxi recent years has been the most serious one in China. The flood crest usually occurs form Apr. to Aug. The important flood protection zone in Jiangxi is Jiangxi reach of the Middle Reaches of Changjiang River. Since the flood bank underwent the first and second flood protection repair work, flood never occurred in 1998 and 1999.But there still exists a potential flood catastrophe. According to the investigation of the fieldwork, the authors analyze the reasons of the change of river channel and its genetic mechanism in the potential flood bank project.
