Study Of The Effect Of The Reclamation Works On Marine Hydrodynamics And Environmental Erosion And Deposition In The Haizhou Bay Of Rizhao City

With the development of marine economy and its development of ocean resources increasing, particularly in land reclamation project on the promotion of local economic development, such as changes in land use, improve land utilization a positive effect, but the negative impact on the marine environment cannot be ignored, sometimes on the marine ecological environment destruction even quite serious. Especially in recent years, development and utilization of coastal activities continues to increase, the marine ecological environment issues have become increasingly prominent, some degradation of the natural environment of the area, serious threat to marine biodiversity. Evaluation and effective control of marine science projects on marine ecological environment destruction, for the protection of marine biological resources and the maintenance of ecological balance, creating blue economy of Shandong Peninsula area, achieving sustainable use of marine resources, possess very important significance to the healthy and stable development of the economy.This text under Haizhou Bay ecological investigation results,analysis evaluation engineering near waters of environment quality status, combinating on engineering water power environment, and engineering geological, and water pollution incremental and pollutants distribution changes, research results, analysis engineering on ecological environment factor of main effect; For eco-environment and eco-sensitive factors of information, analysis and evaluation of marine life and ecology of the marine ecological impact, which in turn makes the following countermeasures and suggestions on ecological environment protection:First, Process engineering of reclaimed sea may damage larvae of fish eggs in floating in the water. For better conservation of marine living resources, dredger jobs should avoid eggs larval breeding of Prime, choice in autumn and winter.Second, the possible construction of suspended sediment of small craft, construction should as far as possible when selecting small storms the weather, to narrow the range of suspended sediment diffusion, reducing impact on the ecological environment, reduce the loss of marine living resources. Construction needs attention during the dredging area of, maintains single ring sting echiuroid ecological stability of protected areas.Third, construction area of manual release should be avoided in order to reduce the loss of seed resources.Forth, taking into account risks of accidents have resulted from engineering of marine ecological environment heavily polluted, be made against hydraulic fill tube cracked, oil spill risk accident, developing emergency response plans and measures, a fast, scientific and effective emergency response system, in the event of accident, able to respond quickly and effectively to an emergency response, pollution incidents can minimize the losses to the biological and ecological environment level.
