Abstract: Abstract:The paper analyzes the status quo of this sea area through the ocean environment monitor materials of Xiamen west and east sea area during July the inter-tide period in 2008 and conducts comprehensive evaluation and analysis on the ocean environment by the way of BP artificial neurology network. The result shows that the overall condition of sea water quality around east-west sea area, Tongan Bay, south-west sea area, except that inorganic nitrogen and phosphate (exceptions) are over proof. The other monitor index meets the corresponding standards. The comprehensive evaluation analysis shows that the overall environment difference of water quality on both sides of Xiamen Gaoji seawall is obvious. The water quality of west sea area is stable. The difference between big and small tide of Tongan Bay is huge. After the bank is broken, the tendency towards stable west sea area environment is bound to be destroyed. It is suggested that there should be strengthened measure on the monitor of pollutant discharge around Tongan Bay and sensitive creature protection at the beginning of the seawall break-up.
