| 摘 要： | 近年来,大亚湾周边的经济和人口快速发展;自1994年大亚湾核电站运转以来,大亚湾的海洋环境和生态状况尤其受到关注。本研究利用实测和卫星遥感数据比较和分析了大亚湾水温和藻华在1983—1993和1994—2004两个时期的变化情况。结果表明:大亚湾核电站运转后(1994—2004)比运转前(1983—1993),年平均表层水温和表层叶绿素 a 含量分别升高1.1oC 和1.9 mg/m3;月平均有害赤潮(HAB)的发生次数也有增加;有害赤潮在 1994 年以前只出现在春季和秋季,而在1994年以后则全年都有发生;表层水温、叶绿素和有害赤潮发生次数都在5月份增加最明显。这些水环境和生态变化与来自大亚湾核电站的热排放以及由于人类活动增加导致的水体富营养化有关。 |

| Abstract: | Economic development around the Daya Bay, China has profoundly affected the marine environment in the bay area in recent years, particularly since the operation of Daya Bay Nuclear Power Station (DNPS) in 1994. This study analyzed the changes of water temperature and harmful algal blooms (HABs) for two periods: 1983-1993 and 1994-2004, using in situ and satellite data. Results showed that yearly mean surface water temperature (SWT) and Chl-a concentration (Chl-a) increased by 1.1 ℃ and 1.9 mg/m3, respectively, after 1994. The monthly occurrence of HAB was found to have increased also. HABs appeared only in spring and autumn before 1994, but occurred all the year round after 1994. SWT, Chl-a and HABs all increased significantly in May. Those changes were associated with environmental changes in this area, such as thermal discharge from the DNPS and enhancement of eutrophication from human activities around the Daya Bay. |
