摘 要:随着人口的增加以及经济的发展,盐城海岸湿地资源利用变化不断加剧。在从时间变化和空间差异角度对盐城海岸湿地资源利用现状进行宏观分析的基础上,文章具体分析了湿地资源利用对水环境和生物多样性的生态效应。结果表明:水质不断恶化,生物多样性受到严重威胁,海岸湿地景观斑块数增加,平均斑块面积减小,破碎化程度加大。进而提出盐城海岸湿地资源可持续利用的生态优化方案,包括生态功能规划、生态产业规划、生态系统管理等措施,以此缓减由于不合理的开发利用对海岸湿地资源的压力,实现其良好状态的维持和海岸湿地资源的可持续利用。With the increase of population and development of economy along coastal wetland in Yancheng, the extent of wetland utilization becomes more intensely. Based on the macro- scopic analysis from the time variation and the spatial difference angle to present situation of the seacoast wetland resources utilization in Yancheng city, ecology effect that water environment and biodiversity are influenced by wetland resources utilization is specifically analyzed in the paper. And the result indicated that water quality unceasingly worsens and biodiversity receives serious threat, the coastal wetland landscape mottling number increases, and the average mottling area reduces, and the broken degree enlarges. Subsequently, the ecological cybernetics measures are proposed as follows, ecological planning and design, ecological industry and ecosystem management and so on. The irrationality utilization of seacoast wetland resources is existence, and the ultimate purpose is to provide an effective model and measure for coastal wetlands utilization, and to diminish multiple kinds of environment pressure and to realize sustainable utilization of coastal wetland resources in Yancheng.
