行政区划调整背景下芜湖市岸线资源的时空演变与优化

SPACE-TIME EVOLUTION AND OPTIMIZATION OF WUHU COASTLINE RESOURCES IN THE BACKGROUND OF ADMINISTRATIVE DIVISION ADJUSTMENT

20世纪50年代港口地理学产生以来,港口体系的形成与演化、港口与腹地的交互作用、航线网络结构与组织等方面的内容受到国内外学者的广泛关注,而岸线资源的时空演变、合理开发与规划管理等相关内容未能引起学者们的高度重视,仅有的研究多数散见于流域开发与管理、港口规划、河道演变与治理等相关领域的研究报告中。以沿江城市芜湖为研究对象,在行政区划调整的战略背景下,将其可利用岸线资源的空间演变划分为沿中江发展、沿青弋江发展、沿长江北扩、沿长江南延、一江两岸统筹发展等5个阶段。以此为基础,选取岸前水深、岸线稳定性等指标综合判别"新芜湖"的岸线资源等级,并结合后方腹地岸线需求对岸线开发进行功能分区,最后总结了"新芜湖"岸线资源开发利用中存在的主要问题,并提出相应的调整优化措施,如实施两岸联动策略、制定岸线准入制度、实行岸线有偿使用、建立岸线调整体制等。

Since the 1950s,the scholars at home and abroad pay extensive attention to the formation and evolution of port system,the interaction between port and hinterland,the structure and organization of line route network and so on,while they ignore the evolution,development and protection of coastal resources.Taken the basin on Wuhu city which stands along the Yangtze River as the example,the article divided the spatial evolution of the shoreline resources into five stages in the background of administrative division adjustment,such as along the Zhongjiang River development stage,along the Qingyi River development stage,along the Yangtze River to the north expansion stage,along the Yangtze River to the south extension stage,along the Yangtze River both sides stage etc.On this basis,the article selected the indicators of water depth before shoreline and shoreline stability to evaluate shoreline resources in the ＂new Wuhu City＂,and conducted the functional zoning of shoreline combined with the hinterland coastline demand.Finally,the article explored the change of shoreline resources and the development and utilization of shoreline resources after the administrative division adjustment in Wuhu city.Then the shoreline resources adjustment and optimization measures were put forward,such as developing shoreline access system,implementing the compensation for the use of shoreline institution,establishing the shoreline adjustment organization,strengthening coastline reserve management and so on.
