Considering factors such as the distribution of tidal stream energy, bathymetry, topography, and the design parameters of the turbines, an appropriate location for a demonstration tidal turbine was selected and the corresponding energy resource was evaluated. Several sites with strong tidal streams were considered： south of the northern cape, east of the southem cape, and the southern end of Haitan Bay. The former was thought most suitable for the deployment of a tidal energy turbine, with projected power generation for approximately 470 h per month. The average power of this demonstration was about 2.4 kW, and the annual electricity output was approximately 17.47 MWh. The intervention of the turbine device had little influence on the near-field tidal stream or water level. The tidal stream was reduced slightly in the area south of the northern cape, although the effect weakened further from the turbine. Conversely, the velocity increased slightly on both sides of the demonstration site. The difference in current speed with and without the turbine was greater at slack tide than still tide. The influence of turbine operation on water level was minor. The method adopted in this study can be considered a reference for the selection of sites for the demonstration of tidal stream energy. However, the method is unable describe the dynamic characteristics of the turbulent flow surrounding the deployed turbines, which has an important role regarding the optimal designs of the turbine blade and pile foundations. Therefore, we will continue to work to improve this model in future research.展开更多

Their content ranges (the mean values) in May were 0.32 - 2.02(0.81), 0.007 - 0. 880(0. 235)and 0.008 - 0.052(0.023) mg.m-3, respectively; those in Oct. were 0.52 - 1 .79(0. 88), 0.007- 0.800(0.301) and 0.021 - 0.060(0.035)mg.m-3. The metals in May and Oct. had markedly different areal distributions characteristics mairily caused by mixing of various water systems. There were positive relationships between dissolved Cd and inorganic N in May, and between dissolved Cd and soluble phosphate in Oct. The obtained molar raties, △Cd:△N = 1.1 × 10-5 and △Cd: △P= 5.8 × 10-4, were clase to there in plankton reported, showing dissolved Cd’s biogerehemical behaviour and process.展开更多
