长江中下游岸线资源的保护与利用

PROTECTION AND EXPLOITATION OF WATER-FRONT RESOURCES ALONG LOWER AND MIDDLE REACHES OF THE TRUNK STREAM OF YANGTZE RIVER

长江中下游干流相对稳定的岸线变迁特征，形成了其丰富的岸线资源。随着长江产业带建设的启动，岸线资源也将进入大规模开发。但由于岸线资源特有的特征，使其在开发利用过程中不能忽视岸线的保护和河道的治理，历史上的一些经验教训足以说明治理和保护在岸线资源开发利用中的重要性。本文分析了长江中下游岸线变迁的特征，通过对长江干流江苏段的调查研究，认为在目前的长江岸线资源开发利用中，存在着重开发利用、轻治理保护的问题。指出长江中下游岸线资源应树立岸线资源观，贯彻保护利用的总方针。遵循开发与治理，保护和利用相结合；经济、社会、生态效益三兼顾的基本原则。大力实施河道整治，保护有效节点，理顺行政管理体制，充分发挥岸线资源的潜力。

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.
