海岸带提供了生境核心和走廊，维持了整个景观的多样性，它们可以构成区域保护战略的基石。自然环境驱动因子和过度的人类活动是滨海湿地变化的重要原因。许多研究利用遥感图像绘制和评估地方或区域尺度的沿海湿地变化。利用遥感技术和景观指数分析方法，研究盐城国家级自然保护区海岸带湿地的变化。结果表明，1988 - 2006年，草地和芦苇面积显著减少，而农田、养殖池塘和建筑面积持续增加。在经济快速发展和人口增长的巨大压力下，海岸景观的空间格局变得破碎化和异质化。湿地的变化对丹顶鹤的自然栖息地有重要影响。这项研究的结果提供了基本的信息，需要制定措施，可持续管理和保护的YNNR。
Coastal zones provide habitat cores and corridors that maintain the diversity of entire landscapes, and they can form the cornerstone elements of regional conservation strategies. Natural environmental driving factors and excessive anthropogenic activities play important roles in coastal wetland change. Many studies have used remote sensing images to map and assess coastal wetland change on local or regional scales. This paper aims to provide insight into coastal wetland change in the Yancheng National Nature Reserve (YNNR) using remote sensing technology and landscape metrics analysis. The results reveal that grass flat and reed areas have significantly decreased, whereas agriculture fields, aquaculture ponds and built-up areas have continuously increased from 1988 to 2006. The spatial pattern of the coastal landscape has become fragmented and heterogeneous under great pressure from rapid economic development and population growth. The wetland changes have important impacts on natural habitat of the red-crowned cranes. The results of this study provide basic information that is required for developing measures toward a sustainable management and conservation of the YNNR.
