Abstract

During November 20-22, 1998, samples were collected at two stations in the Changjiang Estuary.The nutrients limiting algal growth potential(AGP) are estimated by ratios of dissolved inorganic N to P and by nutrient enrichment bioassays using Skeletonema costatum as the test algae.P was severely limited at two stations by the method of ratios of N to P, but by bioassays P was the most important nutrient regulate phytoplankton growth at Sta.1(31°N, 123°E) and N at Sta.2(31°40'N, 122°40'E).The Changjiang Estuary may be divided into three parts:light-limited area, light-and phosphorus-limited area and nitrogen-limited area
- Changjiang Estuary,
- nutrient limitation,
- phytoplankton
