长江岸线资源利用功能区划方法研究——以南通市域长江岸线为例

长江岸线是宝贵的自然资源。依据其资源条件，按照一定的区划原则，确定分段岸线使用的适宜性，合理安排港口、工业、城市生活以及生态保护等各项功能，实现岸线水域和陆域利用的合理布局，对长江岸线资源可持续利用具有重要意义。长江岸线资源利用功能区划必须坚持可持续开发作用、深水深用与浅水浅用、集约布局与纵深发展结合、上下游及左右岸利用方式协调、开发规模和时序与城市和产业发展适应等五条基本原则，区划过程一般包括4个步骤，即划分评价单元、评价岸线资源条件、分析岸线利用现状及需求、分析岸线利用适宜性并完成功能分区。提出了基于遥感与GIS的岸线资源条件和利用现状评价思路，引入了构造联表的岸线开发适宜性分析方法，并且应用这些方法对南通市域长江岸线资源进行了功能区划分。

METHOD TO MAKE FUNCTION DIVISION OF WATERFRONT RESOURSES ALONG THE YANGTZE RIVER——A SAMPLE ON THE WATERFRONT FOR NANTONG CITY

The waterfront resources along the Yangtze River are precious natural resources. It is important for the sustainable utilization of the waterfront resources to arrange the functions reasonably, such as port, manufacture, city life and ecological protection function, according to the natural condition, predefined principles and the suitability of each part of the waterfront. The function division of the waterfront resources should be based on the following principles: ensuring sustainable development, deciding the use according to the depth of the water, combining the intensive arrangement and inland development reasonably, harmonizing the use modes between the upper and lower reaches, the left and right banks, and making the intensity and schedule of the exploitation adapting to the development stage of the city and industry. To make the function division of the waterfront, the first step is to divide the evaluation unit, the second is to evaluate the waterfront resources conditions, the third is to analyze the status and demand of the waterfront utilization, and the last step is to study the suitability of each part of the waterfront resources and finish the function division. The paper introduced the resource evaluation process based on RS and GIS, and expatiated the suitability analysis method by constructing the union-table. By these methods, the paper works out the function division of the waterfront resources of the Yangtze River within Nantong City.HJ1] HJ]
