Sustainable exploitation and utilization of coastal zone space resources has become the major issues to be resolved in most coastal regions,with the fast development of land space devel-opment becoming increasingly saturated and marine economy developing rapidly.Spatial regulation is the hot spot in the planning domain in recent years and an important way to adj ust the sustainable development of society,economy and environment.This paper calculated the com-posite scores of coastal zone protection and utilization suitability by evaluation index system models,which include five kinds of factors,such as topography,urban and transportation,natural ecol-ogy,the utilization of sea coastal zone and the unclear purpose of coastal zone and a total of 23 concrete evaluation indexes,by using the theory of ecological security pattern and land suitability evaluation method,based on the present situation and the stage characteristics of coastal zone pro-tection and utilization.The space control partition of coastal zone for Sanya City was determined by using spatial analysis module combined with Arcgis,which was divided into four classes:the strictly controlled developing zone,the restricted developing zone,the important developing zone and the optimizing developing zone.Ideas and suggestions for the division of spatial regulation a-bout coastal zone in Sanya City were also put forward.%随着陆地发展空间开发日益饱和及海洋经济快速发展,对海域海岸带空间资源开发利用的范围和规模迅速扩大,可持续开发利用海域海岸带空间资源已经成为多数沿海城市区域面临的重大问题.空间管制是近年来规划界关注的热点理论,是一种调节社会、经济、环境可持续发展的重要方式.文章基于三亚市海域海岸带空间保护与利用的现状和阶段特点,采用生态安全格局理论、土地适宜性评价方法构建包括地形地貌、城镇与交通、自然生态、海域海岸带开发利用、未明确用途海域海岸带等5大类因素,23个具体评价指标的评价指标体系模型,计算海域海岸带保护与利用适宜性的综合得分;然后结合Arcgis软件,采用空间分析模块对三亚市海域海岸带进行空间管制分区,分析结果划分为4类区域,即严格管控开发区、限制开发区、重点开发区和优化开发区;最后根据分区结果提出三亚市海域海岸带不同空间管制区域的管控要求与引导建议.
