Abstract


Shenzhen Bay Marina leisure zone is located in the southeastern part of the Nanshan District, Shenzhen, facing the Shenzhen Bay, is the only dense urban coastal belt of the city of Shenzhen, is an important project for the construction of Shenzhen eco-city, to strengthen coastal city characteristics to improve the urban functions. Burden on the marine environment due to the need to use parts of the ocean, land reclamation project in the process of building a certain impact, therefore, the research project to the waters where the impact of scientific evaluation project on coastal recreation zone Shenzhen Bay has important theoretical and practical significance for the sustainable development and use of the protection of the marine resources of the Shenzhen Bay. The papers from the protection of the marine environment, the preservation of the marine ecological balance, and strictly control new pollution point of view, first analyzed with sea marine engineering characteristics of the Shenzhen Bay Coastal Recreation with research projects during the construction and after the completion of major pollutants, and pollution The main link to determine of coastal leisure with engineering evaluation factor. Based on the collection of observations and Social Survey of years of hydrological meteorological Shenzhen Bay Shenzhen Bay's natural environment, social environment conditions described. Cloth point sampling in Shenzhen Bay water quality, sediment, biological survey and analysis of the project, using a single standard index, biodiversity index method to analyze the survey results, the evaluation of projects where the environmental quality of the Shenzhen Bay the status quo. Suspended solids generated by two-dimensional sediment transport diffusion equation, the Pearl River estuary river network two dimensional sea flow models, simulation and predictive engineering, land reclamation currents caused by changes in the marine environment of the Shenzhen Bay. Through the study of the environmental quality of Shenzhen Bay and engineering simulation and prediction of the results of the waters, concluded: 1. Shenzhen Bay due to the impact of land-based pollution and coastal nutrient emissions by a certain degree of pollution, the findings Shenzhen Bay seawater active phosphate and inorganic nitrogen exceeded the phenomenon are very serious; petroleum sulfide sediment quality. Shenzhen Bay Coastal Recreation with marine construction period of major pollutants suspended substance (SS) have a certain impact on water quality environment, at the same time by the impact of the reclamation of the intertidal zone and benthic be buried and death, but they Shenzhen Bay, is temporary, until it disappears with the end of construction will gradually abate. Shenzhen Bay Coastal Recreation with marine construction reclamation will occupy 0.3% of sea areas in Shenzhen Bay, according to the project area cell flow field simulation results show the negligible impact of the project before and after the Shenzhen Bay sea current power, therefore, construction of the Shenzhen Bay waters topography, hydrology dynamic environment will not cause a significant impact. Construction projects for the economic losses arising from the adverse impact of the Shenzhen Bay marine environment, and the economic, social and ecological benefits after the project is completed, it is quite small, the impact of construction projects on the marine environment acceptable. The paper also likely impact of the Shenzhen Bay Shenzhen Bay Coastal Recreation with marine engineering, practical control and reduce the adverse environmental impact of environmental protection countermeasures and measures to strive for the adverse environmental impact of construction projects brought down to minimum, so that the quality of the environment of the sea area where the project is to be effectively protected, to achieve sustainable development and utilization of marine resources of Shenzhen Bay.
