Description
Technical field
The invention belongs to eco-environmental quality assessment technique field, offshore waters, a kind of specifically coastal waters eutrophication evaluation model and operating system construction method thereof.
Background technology
Eutrophication has been destroyed the ecologic equilibrium in waters, makes the change of original ecosystem recurring structure and the degeneration of function, and causes breaking out of red tide.River mouth and coastal waters eutrophication are serious environmental problem of puzzlement coastal countries.As the first river mouth of China, the entrance of Changjiang River is China most important spawning ground of coastal waters aquatic animal, fatten and the habitat.But along with the increase of Yangtze river basin development of industry and agriculture and population in recent years, the entrance of Changjiang River eutrophication also is on the rise, and has become one of district occurred frequently of China's harmful algal.In order to protect the ecologic environment of entrance of Changjiang River better, for government and enterprises and institutions etc. provides the administration base of science, the eutrophication degree of estimating the entrance of Changjiang River objectively has great importance.
Because the geographic position and the weather of offshore waters there are differences, the unified standard that does not have the coastal waters eutrophication to estimate at present in the world.Existing coastal waters eutrophication evaluation method mainly is based on fresh water eutrophication evaluation method; In 2005 24 volume 3 phases " marine environment science " " entrance of Changjiang River and contiguous waters eutrophication present situation and variation tendency " literary composition; Main evaluation method comprises eutrophication exponential sum organic contamination index, adopts water-quality guideline such as nitrogen, phosphorus nutrition salt and COD.But; Because waters, entrance of Changjiang River zones of different there are differences the abundant susceptibility of nutritive salt; For example rolled up in 1 phase " Hydrobiologia " in 2006 563 and point out in " The status and characteristics of eutrophication in the Yangtze River (Changjiang) Estuary and the adjacent East China Sea; China " literary composition; The abundant nutritive salt in the muddy district of mouth door does not cause serious eutrophication symptom appearance, and the nutrient concentration in waters is relatively low to the east of the muddy district, tangible eutrophication symptom but occurred; Therefore, only rely on water-quality guideline such as nutritive salt to be difficult to the eutrophication in waters, objective appraisal entrance of Changjiang River.For this reason; The researcher rolled up in 11 phases " Marine Sciences " 2008 19 volume 1 phases " hydroscience progress " and 2007 31 and writes articles " entrance of Changjiang River and contiguous marine site eutrophication level thereof are estimated " and " utilizing fuzzy synthetic method to estimate CHANGJIANG RIVER ESTUARY SEAWATER eutrophication level " respectively; Adopt fuzzy assessment method and artificial nerve network model method that the MATTER IN CHANGJIANG ESTUARY eutrophication is estimated, increased surface water phytoplankton chlorophyll a and dissolved oxygen DO etc. as evaluation index.But the cardinal symptom in the eutrophication water is the anoxic of bottom water body, rather than the dissolved oxygen DO of surface water.Therefore, it is less to indicate the response index of the key of eutrophication degree to consider to some in the said method, causes being difficult to estimate objectively the eutrophication degree in this waters.
