南海北部浮游植物的时空异质性研究
Temporal and Spatial Heterogeneity of Phytoplanktons in the Northern South China Sea
摘要
Abstract
The temporal and spatial heterogeneity of phytoplanktons in the Northern South China Sea (NSCS) and its relationship with marine environment were investigated based on the data acquired from the survey on fishery resources and their habitat environment in the South China Sea exclusive economic zone and continental shelf carried out from 1997 -2002 (sponsored by the state program of special marine survey, HY126- 02). The data were analyzed by using GIS spatial analysis model and mapping techniques. The amount of phytoplanktons in NSCS changed from 0. 03 to 4 179 × 104 ind/m3, with an average of 87. 2 × 104 ind/m3, in desceding order of summer, winter, spring and autumn. The phytoplankton density was generally higher in the coast waters than in offshore waters. Areas with high phytoplankton density patched along the coastal waters. The high density patches generally occured in the upwelling areas along NSCS coast, such as the northern and central Beibu Bay, Zhelang, Taiwan Bank and Dianbaiyangjiang area. Patches with high phytoplankton density usually shifted from east to west with seasonal changes of monsoon wind and coast currents.关键词
