Study On The Effect Of The Marine Ecological Environment On Reclamation Works

With the development of marine economy and its development of oceanresources increasing, particularly in land reclamation project on the promotion oflocal economic development, such as changes in land use, improve land utilization apositive effect, but the negative impact on the marine environment cannot be ignored,sometimes on the marine ecological environment destruction even quite serious. Tonot only swallowed up large areas of wetland reclamation and weaken the currentvelocity, accelerate the sedimentation, sediment composition change, which affectsthe filter-feeding shellfish farming. Especially in recent years, development andutilization of coastal activities continues to increase, the marine ecologicalenvironment issues have become increasingly prominent, some degradation of thenatural environment of the area, serious threat to marine biodiversity.With the development of marine economy and environmental sciences, researchand understanding of the marine ecosystems, Ocean project on the ecologicalenvironment effect evaluation of more and more people’s attention and the attentionof management. Evaluation and effective control of marine science projects on marineecological environment destruction, for the protection of marine biological resourcesand the maintenance of ecological balance, creating blue economy of ShandongPeninsula area, achieving sustainable use of marine resources, possess very importantsignificance to the healthy and stable development of the economy.This under ecological investigation results and marine history information ofcomparison analysis, analysis evaluation engineering near waters of bio ecologicalhealth status and ecological sensitive problem; by analysis research this waters aboutof ecological environment investigation information and site ecological investigationinformation, evaluation engineering near waters of environment quality status,combination other research topics on engineering water power environment, andengineering geological, and water pollution incremental and pollutants distributionchanges, research results, analysis engineering on ecological environment factor ofmain effect; For eco-environment and eco-sensitive factors of information, analysisand evaluation of marine life and ecology of the marine ecological impact, which inturn makes the following countermeasures and suggestions on ecological environmentprotection:First, Process engineering of reclaimed sea may damage larvae of fish eggs infloating in the water. For better conservation of marine living resources, dredger jobsshould avoid eggs larval breeding of Prime, choice in autumn and winter.Second, the Engineering operations require proper treatment of sewage,discharge in deep water, to relieve pressure on the environment of the sea, avoidfrequent red tide.Third, the possible construction of suspended sediment of small craft,construction should as far as possible when selecting small storms the weather, tonarrow the range of suspended sediment diffusion, reducing impact on the ecologicalenvironment, reduce the loss of marine living resources. Construction needs attention during the dredging area of, maintains single ring sting echiuroid ecological stabilityof protected areas.Forth, construction area of manual release should be avoided in order to reducethe loss of seed resources.Fifth, in order to maintain the balance of the ecological environment of waters,should comply with the marine environmental protection regulations, strengthen thecontrol of sea pollution, reduce land pollution sources on effect of ecologicalenvironment in Bohai Gulf coastal waters.Sixth, in the course of construction, marine pollutants should be strengthened inships ’ ballast water and heating oil, tank washing water and fuel oil, oily waterdischarge of supervision and management, strengthening the monitoring of suspendedsediment and other main pollutants, reduce environmental pollution accidents fromhappening.Seventh, taking into account risks of accidents have resulted from engineering ofmarine ecological environment heavily polluted, be made against hydraulic fill tubecracked, oil spill risk accident, developing emergency response plans and measures, afast, scientific and effective emergency response system, in the event of accident, ableto respond quickly and effectively to an emergency response, pollution incidents canminimize the losses to the biological and ecological environment level.
