Study on the Chlorophyll-a and Primary Production in the Luanhe–Beidaihe Estuary
The chlorophyll-a and the primary production on different sections in the Luanhe-Beidaihe Estuary in August 2007 respectively ranged from (2.9 ± 0.5) to (10.5 ± 2.0) ( mg/m3 ), and from (14.9 ± 3.4) to (84.0 ± 7.6) (mgC/m2∙d). The chlorophyll-a concentration and the primary production in the southern part (section A-section E) were more than that in the northern part (section F- section H). It would suggested that the agriculture and aquiculture in the southern part imported more nutrients than that of the leisure and recreation industries imported in the the northern part, and the discrepancy of chlorophyll-a concentrations and primary production of different sections should be resulted from the different intensity of people activity in these areas.
