加快长江中下游河道治理　促进沿江经济带建设发展

Speed up middle-lower Yangtze' s river regulation, promote riparian economic belt's development

长江中下游干流地带，自然地理优越，分布有许多大中城市、重要港口，而且工农业发达，成为经济发展和对外开放的热点地区。随着该地区进一步开发开放，对河道的利用提出更高要求。目前长江中下游河道仍然存在不少问题，不同程度地制约沿江地带经济正常发展。如局部河段主流摆动和崩岸；一些港口码头、给排水口淤积；泄洪能力小于洪水来量；有些河段的河道形态不利于泄洪、航运等等。因此，中下游干流的河道治理是沿江经济带发展的基础建设。为促进沿江地区成为我国经济发展先行区，必须加快河道的治理。

The middle and lower Yangtze river main stem zone is in advantageous natural conditions and geographical positions.In this zone,there are many big cities and ports,and the industry and agriculture are flourishing,so that it becomes an area with fast-developing economy and increasing attractiveness to outside world.Higher requirements for utilization of the middle and lower Yangtze river channel are put forward.At present,the middle and lower Yangtze river channel is still faced with a lot of problems restricting to a certain extent the normal development of this important part of the Changjiang economy belt.These problems are:fluvial swinging of channel alignment and erosion in local river stretches; scouring and silting of ports,wharfs,intakes and drainage outlets; inadequate flood releasing capacity of the channel;unfavorable local conditions of some stretches for flood releasing and navigation etc.Therefore regulation of the middle and lower Yangtze river stem is a fundamental prerequisite to the development of the Changjiang economic belt including both banks of the river,the neighboring lake region and the river itself.In order to speed up the economic growth of this zone to play a vanguard role in the development of China's economy,it is necessary to place regulation of the river channel on the agenda as one of nation's priorities.
