【摘要】 在EVNI4.8、SPSS17.0与ARCGIS10.0软件平台的支持下,选择广西北海地区近海海域为研究区域,以2010年SPOT5高分多光谱数据为基础,运用双变量相关分析法,分析了红树林湿地景观格局与近海海域水质的相关性。结果表明:红树林湿地景观格局对近海海域水环境质量具有一定的表征作用。景观总面积、破碎度、多样性及优势种是表征水环境质量的主要指标。景观格局指数与水质参数之间存在一定的相关性:景观总面积（TLA）与透明度显著正相关,斑块个数（Num P）与盐度显著正相关、与化学需氧量（BOD）显著负相关,平均斑块分维数（MPFD）与氨盐（NH⁺₄）显著负相关,平均斑块面积（MPAR）与亚硝酸盐（NO^-₂）、硝酸盐（NO^-₃）和无机磷（P）显著负相关,多样性（SDI）与汞（Hg）显著正相关。其余景观格局指数与水质参数指标在数量上的相关性不明显。更多还原

【Abstract】 With the support of EVNI4. 8,SPSS17. 0 and ARCGIS10. 0 software platform,it analyzes the correlation between mangrove wetland landscape pattern and water quality in coastal waters by using the bivariate correlation analysis,by which chooses the offshore waters in Guangxi Beihai region as the study area based on the high multispectral data of SPOT5 satellite in 2010. The results show that the mangrove wetland landscape pattern has a certain representation of water quality in coastal waters. The landscape area,fragmentation,diversity and dominant species are the main indicators affecting the quality of water environment. There is a certain correlation between landscape pattern index and water quality parameters which is a significant positive correlation between TLA and transparency,a significant positive correlation between Num P and salinity,a significant negative correlation between Num P and chemical oxygen demand（ BOD）,a significant negative correlation between MPFD and ammonium salt（ NH⁺₄）,a significant negative correlation among MPAR,nitrite（ NO^-₂）,nitrate（ NO^-₃） and inorganic phosphorus（ P） and a significant positive correlation between SDI and mercury（ Hg）. The correlation is not obvious between other landscape pattern index and water quality parameters.更多还原
