摘要
填海类用海是深圳改革开放以来发展较为迅猛的用海方式之一,过往的研究大多围绕深圳市过度填海对海洋环境的影响开展讨论,极少对深圳市海域进行定级方面的研究。借鉴《海域定级技术指引(试行)》,本研究构建了深圳市填海类用海的海域定级指标体系,创新性地引入一票选择机制,并将工业、交通运输、渔业基础设施等填海用海和城镇建设填海用海合并,统一为填海类用海进行定级。采用专家打分法确定定级因素和评价因子及其权重,通过聚类分析方法和变异系数(CV)来校核级别,将填海类用海划分为4个级别。该研究为沿海地区开展填海类用海定级提供参考。
Sea reclamation is one of the rapidly developing sea area use mode that have developed rapidly in Shenzhen since the reform and opening up.Most of the previous studies have focused on the impact of excessive reclamation on the marine environment in Shenzhen,whereas few studies on the grading of the sea area were car-ried out.Using the Technical Guidlines for Sea Area Grading(Trial)for reference,this study constructed the sea area grading index system of Shenzhen’s sea reclamation,innovatively introduced a selection mechanism,and combined the sea area used for reclamation by industry,transportation,fishery infrastructure and urban construction,so as to unify the sea area used for reclamation to grade.The grading factors,assessment factors and their corre-sponding weights were determined by expert scoring method.The grades were checked by cluster analysis method and coefficient of variation,and the reclaimed sea was divided in to 4 grades.This study provides a reference for the grading of sea reclamation in coastal areas.
