江苏省泰州长江岸线利用演变及影响因素分析

岸线利用管理是促进岸线资源集约利用,支撑沿江开发有序、健康推进的重要保障。以泰州长江岸线利用时空变化数据库(2003~2013年)为基础,构建岸线利用类型转移矩阵,关联岸线类型与岸线条件,从规模扩张、结构变化和类型转移三方面分析岸线利用时空变化特征,结合政府部门和企业访谈以及相关研究,剖析岸线利用变化的影响因素与作用特点,为岸线利用政策调整提供依据。实证分析表明:沿江开发实施以来,泰州长江岸线利用扩张迅速,但2009年之后扩张减缓,优质岸线利用率较高,后备岸线不多。2009年以前,岸线开发以工业、仓储和港口等生产性占用为主,旅游休闲、生态保护与污染处理岸线也有较多增长。2009年之后,港口岸线扩张占主导地位,取代工业岸线成为已利用岸线调整和未利用岸线开发的主要方向。贴岸产业开发模式向港产城一体化综合开发的转变及岸线管理政策的调整共同驱动了岸线利用从工业主导向港口主导的转变,促进了岸线利用从规模扩张向结构优化转变。

ANALYSIS ON THE TENDENCY AND INFLUENCING FACTORS OF WATERFRONT RESOURCES UTILIZATION CHANGE ALONG THE YANGTZE RIVER IN TAIZHOU CITY

Waterfront Resources Utilization has played a key role in regional economic development. Scientific management of waterfront comprehensive utilization has an important effect on sustainable development in the area along the Yangtze River. In this paper, based on the comparative analysis of definitions on the types of waterfront utilization，the database consisting of the variation informations about waterfront resources utilization (between 2003 and 2013) has been constructed. Later, the matrix which reflects the waterfront utilization change was set up, and the analysis of relationship between the type of waterfront utilization and the class of waterfront resource was carried out. In the end, the characteristics of waterfront utilization change were explored, the driving factors of waterfront utilization change and their effects were discussed, then the advice on enhancing waterfront utilizations benefits was put forward. Empirical analysis of the waterfront along the Yangtze River in Taizhou City showed that the waterfront resources utilization has rapidly expanded since 2003, but the expanding velocity became lower after 2009. So far, the waterfront resources utilization ratio has exceeded by 50%, and the reserve waterfront resources has become less and less. Between 2003 and 2009, waterfront utilization expansion for manufacture, port and warehouse tended to dominate, and manufacture held a leading post among them, at the same time, waterfront utilization for tourism and ecological protection also increased sustainably. After 2009, waterfront utilization expansion for port was predominant, and the ratio of waterfront utilization for manufacture began to decline obviously. Not only most part of the waterfront which had not been developed but also much developed waterfront was used for ports during the past 4 years. Though the natural conditions has main effect on the variation of waterfront utilization structure, coupling between natural conditions and other economic and social factors such as regional economic development model promotes waterfront utilization transformation which is from manufacture led model to port led model. In recent years, the formulation and implementation of policy on waterfront resources utilization management in Taizhou city has played powerful role in improving waterfront utilization benefits. In the end, we can draw the conclusion that rational policy can provide strong support for encouraging public utilization for port and others, and maximize the waterfront utilization benefits. In the future, the government of Taizhou city should pay much attention to innovation of waterfront resources utilization management policy, and choose the suitable policy which can guide the waterfront resources utilization, and this may be useful to the development of industry and cities in the area along the Yangtze River in Taizhou city. This study may also give some advices on resource utilization to other cities.〖JP〗〖HJ1〗〖HJ〗〖HQ〗
