The channel characteristics of meandering and anstomosing at the Jianli Reach in Jingjiang River are introduced, and the river landscape evolution history during recent hundred years is described. The changes of thalweg, the evolutions of central and point bars, the diversion ratio of branching channel and the change character of discharges of water and sediment are analyzed. With the implement of river regulation projects, the Lower Jiangjiang River was developed from typical meandering channel to limited meandering channel. According to preceding analysis, It can be concluded that the main flow of Jianli Reach is stabilized on the right branche. The conclusion, however, is conflicting to the report of “The Main River Improvement Planning of Middle and Lower Reaches of Yangtze River” approved in 1998. Based on the conclusion, a preliminary consideration is proposed on flood control planning, shoreline utilization and city area development of Jianli Reach. This suggestion may better solve the questions of river navigation and flood control of Jianli Reach, and establishes a good foundation for a long- term river regulation of Jingjiang River.
