Abstract
Statistical analysis of hydro-meteorological data from 2010 to 2015 in Wenzhou coastal waters was done. The results indicate that: Prior to occurrence of red tide in Wenzhou coastal waters, the ocean water temperature always shows a rising trend and the salinity commonly sustains or shows a declining trend. The wind speed is low and the main wind directions are northeast, southwest and southeast. The monitoring data of red tide in Wenzhou coastal waters from 2003 to 2015 was analyzed, the results show that: (1) Red tides in Wenzhou coastal waters happen frequently. These red tides could happen from March to September and most of them happened during May and June;(2) The lasting time of red tide in Wenzhou coastal waters is long and the average lasting time is 8.1 days;(3) The occurrence area of red tides were large and the average occurrence area of each red tide was 111.2 km2. The maximum occurrence area was 1000 km2;(4) Most red tides happened in coastal waters of Cangnan, Dongtou and Nanji. The number of red tides happened in Nanji coastal area was high which was about 52.6%of total occurrence;(5) The species of red tide plankton have an obvious phenomenon of succession;(6) Poisonous red tides happened frequently in Wenzhou coastal waters. The major red tide plankton causing poisonous red tides were Karenia mikimotoi and Heterosigma akashiwo.关键词
