摘要
为了评价大长山人工生境开发示范区水质环境,于2013—2015年对大连长海县大长山岛人工生境开发示范区进行了8个航次的环境调查,获取了盐度、pH、COD等20个水化学指标,并利用主成分分析法及单因子指数法研究分析了该海域的水质状况。结果表明:除2014年8月航次对照区属Ⅱ类海水标准外,其余航次、站点调查结果均显示大长山海域符合Ⅰ类海水标准;用主成分分析法将20个指标分为了6个主成分,解释了79.165%的结果;主成分得分范围为-1.535~3.706,其中,2014年8月得分最高,评价结果与单因子指数分析结果基本一致。研究表明,大长山人工生境开发示范区整体水质良好。
The water parameters including salinity, pH, and COD were monitored in eight environment voyages in Daehangshan island ar6fieial habitat development demonstration area of Changhai county, Dalian, from 2013 to 2015 to evaluate the system of Daehangshan water environment of artifieial habitat development demonstration area, and analyzed by principal component analysis （PCA） and single factor index method to evaluate the water quality in the area. The results showed that the water quality in most area of Daehangshan waters met the first kind of sea- water standard, except that control plot of the August 2014 voyage belonged to second kind water standard. The principal component analysis （pea） indicated that 20 indices failed into six main components, explaining 79.165% of the results, with principal component score of -1.535 to 3.706, the maximal score in August 2014, and consist- ent with the single taetor index. The findings indicate that the overall water quality is good in Daehangshan artificial habitat development demonstration area.
