[Analysis on the spatial characteristics of the light quantum yields in Lake Taihu in spring].
Based on the primary productions and underwater irradiance in the head of the jetty in a station of the Lake Taihu ecology network of the Chinese academia, Zhihugang estuary area, the center of Lake Taihu and Xukou Bay at April 28, May 4, May 5, May 6 in 2009, the light quantum yields of algae and P-I curve were calculated. Then the spatial characteristics were analyzed. There was significant photoinhibition in the head of the jetty in a station of the Lake Taihu ecology network of the Chinese academia; there was not appreciable photoinhibition in Zhihugang estuary area and the center of Xukou Bay; and there was only light-saturation phenomena in the center of Lake Taihu. The order of the light quantum yield per Chl-a was the center of Lake Taihu, the head of the jetty, Zhihugang estuary area and the center of Xukou Bay.
