摘要
海岸线资源综合评价是提高海岸线利用综合效益的基础,也是合理开发海岸线的重要依据之一。本研究从生产、生活、生态3个维度选取指标,构建海岸线资源开发适宜性评价指标体系,基于GIS技术对海口市海岸线资源进行开发适宜性综合评价。结果表明:海口市海岸线的开发强度较高,中心城区>西部片区>东部片区,其中生产岸线、生活岸线、生态岸线、储备岸线分别占岸线总长度的13.61%、38.01%、39.48%、8.90%;海口市海岸线资源按照开发功能可分为港口码头、渔业养殖、生活旅游、生态保护、储备岸线等5种类型,西部片区、中心城区以生活旅游功能为主兼具港口航运功能;生态保护岸线分布在东部片区东寨港岸段。应根据各区域岸线特点做好保护与开发的协调,为海口市海岸线资源的保护与可持续利用提供科技支撑。
Scientific and reasonable evaluation of coastline resource conditions is the basis for formulating coastal development strategies and coordinating functional layout of the coastline.This study selected indicators from dimensions of production,life and ecology,and constructed an evaluation index system for the development suitability of coastline resources.Based on GIS technology,the comprehensive evaluation of the development suitability of Hai-kou coastline resources was carried out.The results show that Haikou coastline is in a high intensity of development,of which 13.61%is composed of industrial shorelines,38.01%is living shorelines,39.48%is ecological shorelines and 8.90%is reserved shorelines.The coastline of the central city has the highest development intensity,followed by the western area,and the eastern area has the least development intensity.The shoreline resources can be divided functionally into 5 types as port,fishery aquaculture,living and tourism,ecological conservation and reserved shoreline.The ecological protection coastlines are mainly locatied in eastern Dongzhaigang area,and the western area and the central urban area are dominated by living and tourism functions as well as port and shipping functions.Development and protection should be considered according to the characteristics of the regional coastline in order to provide scientific and technological support for the protection and sustainable use of Haikou's coastline resources.
