【摘要】 柘林湾是粤尔有名的大规模养殖区,由于养殖业的快速发展以及陆源排污排废的影响,该海域富营养化问题日益突出,成为赤潮多发区,给当地渔业利生态环境造成了严重的危害。因此,掌握柘林湾各营养元素的来源、分布规律、进行海洋环境质量评价等是非常必要的。但是传统的研究方法效率较慢,制图困难,数据与图形分离等,不能满足实际需求。本文利用GIS技术进行柘林湾的生态研究,建立了柘林湾生态信息数据库,并利用GIS强大的空间分析技术进行生态分析,实现对海洋环境的质量评价,为粤东海水增养殖业生态环境的持续发展和海湾生态保护策略提供了理论依据和优化决策。更多还原

【Abstract】 Zhelin Bay is a famous estuary for large-scale mariculture in the eastern Guangdong, China. With constantly increasing in fishery culture and nutrient input to the estuaries within decades, the ecological environment has been significantly changed, resulting in harmful algal blooms hitting this area "frequently damage to the ecosystem. Therefore, it is necessary to find out the source and distribution rules of some important elements and assess the marine environment impact. However, the traditional way cannot satisfy the practice requirement with slowly efficiency, difficult to design graph, data and graph discretely and so on. This paper studied ecology based on the GIS technology, built a ecological information database of Zhelin Bay, analyzed ecological information with spatial analysis technology of GIS, and realized the marine environment impact assessment, which supply the theoretic bases and optimizing decision of the continual development of ecological environment and marine ecological protection for mariculture zone in the eastern Guangdong.更多还原
