Abstract:

Under laboratory condition, a stress experiment of four environmental factors (temperature, pH, phosphate and copper) on scleractinian (Porites luteaand Goniopora stutchburyi) was carried. The results suggested the four environmental factors have significant impacts on the areal zooxanthellae density and zooxanthellae chlorophyll-a content of two coral species and show a significant differences between control and treatment (p<0.05). Along with the increase of temperature, the decrease of pH, and the increases of phosphate concentration and copper concentration in the seawater, two coral species were stimulated to have slime secretion at first, and then their tentacle lost activity density and coral surfaces lost colors until

Key words: temperature, pH, phosphate, copper, zooxanthellae, chlorophyll-a, coral
