PROTECTION AND EXPLOITATION OF WATER- FRONT RESOURCES ALONG LOWER AND MIDDLE REACHES OF THE TRUNK STREAM OF YANGTZE RIVER
长江中下游岸线资源的保护与利用

For the relative stable water front, there exist abundant water front resources along the lower and middle reaches of the trunk stream of Yangtze River. But historical experience and lessons tell us the importance to harness rivers and protect their water fronts in the process of exploiting them. This paper analyzes pattern changes of the water front along the lower and middle reaches of the trunk stream of the Yangtze River course since down Chenglingji, it is branched which is advantageous to use the water front resources. On Jinjiang section or on the river mouth, the water front needs harnessing and protecting for flexuous course and siltation. Meanwhile, it also analyzes the problems in the exploitation of water front in Jiangsu Province where more exploitation but less protection has been practiced. The paper puts forward the basic idea that exploitation of river water front, a kind of important resource, should be done under the prerequisite of protection and harnessing. It is very important to work out rational principles concerning water front utilization and resources evaluation. In order to sufficiently exploit the potentiality of the water front resources, protection and exploitation should be fully taken into account for the sake of gaining both socio economic and ecological benefits. River channel regulation should be done energetically and administrative system should be adjusted.
