| 摘 要： | 有效识别和评估各滩涂区域资源开发承载力时空变化的差异, 有利于滩涂资源的科学规划, 对实现沿海滩涂资源的高效利用与保护具有重要意义。本文针对渤海半封闭海湾滩涂特征的空间差异性, 基于"驱动力-状态-影响"模型, 构建了滩涂资源开发承载力评估体系, 对研究区域7个评价单元在4个代表年份的资源承载力进行了评估, 阐明了海湾滩涂资源开发承载力时空演变特征。结果表明: 围填工程减弱了渤海湾滩涂资源开发承载能力, 工程大规模建设期间(2003—2012年)各评价单元承载力均呈下降趋势, 2012年后随着国家围填海管控措施的实施, 滩涂承载力有回升态势; 在空间上滩涂资源承载力表现为湾顶的降幅高于海湾南部区域, 滩涂开发前后天津港附近区域承载力较弱, 黄骅港以南滩涂养殖区承载力较强。

| Abstract: | Effectively identifying and evaluating the differences in the temporal and spatial variation of resource carrying capacity in each tidal flat area is conducive to the scientific planning of tidal flat resources. This is of great significance to the realization of rational utilization and protection of coastal tidal flat resources. Based on the spatial variation of semi-closed gulf beaches' characteristics in Bohai Bay and the "driving force-state-impact" model, an evaluation system for the development carrying capacity of tidal flat resources is constructed. The resource carrying capacity of seven evaluation units during four typical years is evaluated, revealing the temporal and spatial evolution characteristics of the development carrying capacity of the tidal flat resources in the bay. The results indicate that the reclamation project weakens the development carrying capacity of the tidal flat in Bohai Bay. During the large-scale construction of the project (2003—2012), the carrying capacity of each evaluation unit has exhibited a downward trend. Due to the implementation of national reclamation control measures, the carrying capacity has demonstrated a recovery trend since 2012. Spatial analysis reveals that the carrying capacity of the bay roof decreased more than that of the southern part of the bay, the carrying capacity of the area near Tianjin Port is poor both before and after the development, and the carrying capacity of the tidal flat breeding area south of Huanghua Port is strong. |
