摘要
近几年,由于对江苏中部淤长型海岸进行了大规模的围垦,使海堤外迁,潮滩上发育的潮水沟也作大规模的调整?本文通过对潮滩上发育的潮水沟的实地观测资料,对海堤外迁后的潮水沟的变化?发育特征以及治理开发作了较为深入的分析?分析结果显示,在海堤外迁后:(1)随潮滩的淤高?增宽和潮水沟萎缩的同时,潮水沟恢复向多级发育,这种发育具有继承性;(2)可能激活潮水沟加快或减慢弯曲,但人为因素(人工洼地?植被?裁弯等)往往会改变这个过程?
In the last few years, the large area of mudflat has been enclosed and the coast moved toward the sea in depositional mudflat in the middle coast of Jiangsu. This would cause a large-scale changes in the tidal creek on the mudflat. Based on the survey data on the changes in the tidal creek after the enclosure, the paper analyses the course of changes and development characteristics of the tide creek, and put forward the ways of controlling and developing them. After the mudflat is enclosed: 1 ) the tide creek develop continually toward the multistage with deposition and widening of the mudflat, but they bear original characteristics; 2 ) It may activate activity of the tide creek, which curves fast or slowly, but human influences often change the process.
