摘　　要：文章对唐山市沿海地区1991—2015年土地利用和结构变化及其生态系统服务价值进行核算分析和量化评估。结果表明:1991—2015年唐山市海岸带主要地物类型涉及耕地、公路用地、河流水面、建设用地、坑塘水面、盐田、填海用地和裸地,其中坑塘水面占地最多,海岸带开发利用总面积不断增大,用地类型有所转化且向海域扩张,新增用地主要来自围填海且以填海造地为主;海岸带生态系统服务价值呈逐年下降的趋势,以2006—2010年变化最为明显,主要原因为海水面积减少。在充分认识填海造地活动双面性的基础上,建议慎重开展填海造地,集约节约利用海洋空间资源,合理科学规划填海区域,提高海洋资源利用效率。This paper made an accounting analysis and quantitative assessment of land use and structural change as well as ecosystem service value in the coastal areas of Tangshan City from1991 to 2015.The results showed that the land use types of Tangshan＇s coastal zone from 1991 to2015 were mainly arable land,the land for highway,river,the land for construction project,pond,salt pan,reclamation area and bare land,among which the pond occupied the largest area.The total area for development and utilization of the coastal zone were increasing by the day and the land use type has been transformed and expanded to sea area.The newly-increasing land was mainly of reclamation.The ecosystem service value in coastal area has been decreasing year by year,especially during the years from 2006 to 2010,mainly due to the reduction of seawater area.On the basis of fully understanding the two-sided nature of reclamation activities,it is suggested that the reclamation project should be carried out in a prudent manner and marine space resourcesbe used intensively as well as the reclamation areas be planned reasonably and scientifically so as to improve the utilization efficiency of marine resources.
