【摘要】 在综合考虑大亚湾海域及岛群的自然生态属性、资源条件和社会生态属性的基础上,结合有关研究成果,从约束型与引导型两个要素类别筛选指标作为海岛港口开发与保护适宜性分区评价的指标。借助地理信息系统的空间分析功能,采用单因子评价与多因子加权综合评价方法,定量分析了研究区的海岛港口开发适宜性程度及其空间分布特征,并将大亚湾海岛港口开发利用与保护适宜性划分为4级:鼓励开发、适度开发、适度保护与优先保护。结果表明:大亚湾海岛港口开发利用与保护适宜性在空间分布上差异显著。优先保护区域占4.02%,适度保护区域占12.1%,而适度开发区域占到45.47%,鼓励开发区域占38.41%。评价成果对于大亚湾海岛资源可持续利用和港口开发空间秩序的确定具有指导意义。更多还原

【Abstract】 Based on the characteristic of natural ecology,resource conditions and social ecology of Dayawan bay,combining with related research,some key factors are chosen to build the assessment index of suitability for port development and protection of islands,composed of restricted and guiding categories.Using the spatial analysis function of GIS,this paper analyzes the degree of suitability for port development and protection of islands,along with their spatial distribution of study area.According to the level of suitability,the study region is subdivided into four parts: hortative development region,feasible development region,moderate conservation region and preferential conservation region.The result shows that the difference of spatial distribution between these factors was significant.The hortative development region accounts for 38.41% of total area,while feasible development region accounts for 45.47%,moderate conservation region accounts for 12.1%.The preferential conservation region shares the smaller proportion,only accounts for 4.02%.This study could provide scientific references for sustainable utilization of islands resources and space order for port development.更多还原
