A review on primary production studies for China seas in the past 20 years
Ning Xiu · Donghai Marine Science · 2000
The study of primary production in China seas by the Chinese scientists in the past 20 years is reviewed in this paper Along with the increasing importance of resources and environment, more and more attention has been paid to this study. The observed sea areas have been expanded from coastal zone,estuaries,bays and coastal upwelling to the continental shelf and the open seas and from China seas to the ocean and even polara seas. The methodology has much been improved and standardized with international scientific communities The studies have obviously been deepened, which ranges from total primary production to production structures,such as size structure,product structure,function structure and phytoplankton community structure,etc \;Through 20 years\' efforts,phytoplankton standing stock and production in these sea areas have basically been claritied, which provide important scientific bases for the study of structure and functions of marine ecosystems,management of fisheries resources, assessment of marine environment quality and observation prediction of red tide In recent years the studies have closely been connected with specific study objectives,such as assessment of carrying capacity of mariculture,study on eutrophication and red tides,etc , or with international joint research programs,such as JGOFS and GLOBEC The enhancement of large spatial and long term\|series observations using not only research vessels,but also oceanographic buoy,undulating oceanographic recorder with multi\|sensors and satellite remote sensing etc will greatly promote the development of primary production study in these regions
