海域使用管理政策约束下的港口岸线适宜性评价--以珠江口及大鹏半岛为例

Port shoreline suitability evaluation under the constraints of sea area use management policy:A case study of the Pearl River Estuary and Dapeng Peninsula

在分析相关研究、技术指南和港口建设影响因素的基础上,建立了直接判断法与多因子加权开发潜力-生态制约修正模型相结合的港口岸线建设适宜性综合评价方法,定性判断与定量分析相结合实现了港口岸线的适宜性评价。将该方法在珠江口及大鹏半岛区域进行了应用实践和分析。根据评价结果,适宜、较适宜、一般适宜建港岸线分别占该区域岸线长度的29.77%、18.98%和1.55%,不适宜建港岸线为49.70%。评价结果符合现实情况和用海管控政策要求,可为海洋国土空间规划进行港口功能分区提供支撑。

Port construction is one of the important ways to develop and utilize marine resources.The suitability analysis of port construction requires the comprehensive consideration of the social and economic development,the national sea use and control policies,the natural resource conditions and other factors.Based on the analysis of relevant researches,technical guidelines and influencing factors of port construction,this paper establishes a comprehensive evaluation method of port shoreline construction suitability for qualitative judgment and quantitative analysis,which combines the direct judgment method with a correction model restricted by multi-factor-weighted development potential and ecology.The method is applied in the Pearl River Estuary and Dapeng Peninsula.The evaluation results show that the suitable,relatively suitable and generally suitable coastlines account for 29.77%,18.98%and 1.55%of the coastline length of the region respectively,while the unsuitable coastline is 49.70%.The evaluation results meet the actual situation and the requirements of sea use management and control policies,which can provide support for port function zoning in marine territorial planning.The evaluation method can also provide reference for the suitability evaluation of other types of sea use.
