| 摘 要： | 长江口中华鲟自然保护区是中华鲟幼鲟入海前调节和索饵的重要场所,分析和评价保护区生态环境对中华鲟保护具有重要的意义。通过2005年8月和2006年5月和8月保护区调查数据,应用水质单项污染指数、富营养化污染指数和生物多样性指数评价保护区水域生态环境质量状况,评价结果显示:保护区总体处于中度污染水平,该水域受无机磷污染严重,无机氮污染有加剧的趋势,2006年5月保护区富营养化程度最高,而北港水域富营养化水平高于同期其它水域;保护区内浮游植物生物量分布不均,群落结构简单,呈现出2005年8月生物量远高于2006年的5月和8月,而其生物多样性低的反常现象;通过近年来大型中华鲟误捕情况分析生态环境变化和河口工程活动对中华鲟生存的潜在影响。

| Abstract: | The Yangtze Estuarine nature reserve for Chinese Sturgeon is an important place for immature Acipenser sinensis.It has significant meaning to analyze and evaluate the eco-environment of Yangtze Estuarine Nature Reserve for Chinese Sturgeon.According to the analysis of the research data in August, 2005 and in May and August, 2006, the evaluation results indicated that the comprehensive quality was at the level of "middle pollution", and the ecological environment in the Nature Reserve was evaluated by the methods of single parameter pollution index, eutrophication index, and biodiversity index.The pollution of DIP in the Reserve is serious and the pollution of DIN is worsened.The eutrophication level in May, 2006 was the highest.The eutrophication level in North Channel of Changjiang Estuary was higher than the other waters in the same period.The phytoplankton biomass is maldistributed and the community structure is simple and unstable.The phytoplankton biomass in August, 2005 was larger than that of level in May and August, 2006.but the level of bio-diversity was lower in August, 2005.Through analyzing the incidental catches of the large-scale Acipenser sinensis, it was found that the environment change and engineering activities formed the potential hazard to Acipenser sinensis. |
