| 摘 要： | 根据2009年9月广西北部湾近岸的海洋生态调查资料,利用地理信息系统的空间分析功能,从海水水质、营养水平、生物量和初级生产力水平、生物多样性和生态系统缓冲容量5个方面分析了秋季广西北部湾近岸海域环境现状,并进一步利用生态风险综合指数对广西北部湾海洋生态风险进行了评价.结果表明:2009年秋季,广西北部湾近岸海域生态环境质量较好,大部分生态系统风险指标等级均处于“中低”或“较低”水平,整体处于低风险状态.生态风险综合指数结果显示,广西北部湾海域生态风险分布具有明显的空间异质性,离岸水域生态系统的风险综合指数较低,越靠近港湾内,风险状态等级越高.

| Abstract: | Based on the marine ecological investigation in the coastal area of Beibu Gulf,Guangxi in September 2009,a GIS-based evaluation was conducted on the present status of ecological environment quality,including seawater quality,nutrient level,biomass,primary productivity,biodiversity,and ecological buffer capacity,in the area in autumn,and the integrated ecological risk index(ERI) was adopted to assess the risk of the coastal ecosystem in the Gulf.In September 2009,the study area had a better ecological enviro... |
