but also which has accumulated valuable experience for the development of Nansha Islands and has laid a solid construction foundation. The construction side stringent environmental standards for construction: (1) minimize the reclamation and dredging of the area; (2) Set Trash screen in dredging and reclamation process; (3) reasonable arrangements for the construction schedule, try to avoid the construction period Red snapper (mid-April), tuna (for the June-August peak) and bonito (March to August) the spawning period; (4) the regular monitoring take sand sediments grain size variations to ensure get sand area is always coarse sand, fine sand into the reclamation area to avoid,barbour paris, maintain water quality in the coral reefs; (5) as far as the Spratly Islands and the Paracel Islands coral growth decreases the peak construction season strength; the law according to the growth of coral and biological characteristics.
Construction-square analysis of the world's coral reefs in many countries land reclamation,tn, dredging and excavation of the landfill and other projects,air jordan, such as the Bahamas North Abaco draws Port (North Abaco Port),parajumpers france, KCT pier in Kingston,air jordan pas cher, Jamaica,air jordan pas cher, Sudan Savoie Similar Environmental Impact Jingang,hollister, Papua New Guinea, Port of mitigation measures and construction technology content,hollister, and domestic similar analogy analytical work carried out reefs. Meanwhile,toms outlet, China's foreign construction companies to participate actively in the reef dredging and land reclamation works in the actual construction not only mastered a large number of advanced environmentally friendly construction methods.
sub-health and unhealthy three levels. Nansha Islands coral reefs have been included in the sub-health classes. Evaluation Nansha Islands to be the expansion project for ecosystem health effects show that construction is still sub-health state. Therefore, the construction of the reefs of Nansha area unaltered ecosystem health, causing no damage to coral ecosystems. In fact, strong currents and wave action reefs of Nansha Islands waters,jordan pas cher, water updated quickly,air jordan pas cher, suspended sediment from construction rarely, does not influence yellow algae photosynthesis corals; coupled with more due to the construction site in coral reef Low coverage death or region, and therefore the expansion project will not change the community structure of coral area. After completion of construction, as a result of reef-building marine hydrology,giuseppe zanotti femme, sediment status change is limited to the construction area and its small range around coral growth and development of the physical and chemical environment has not fundamentally changed.
dynamic monitor changes in water turbidity, rationalization dredging intervals; (6) regular monitoring growth and health in the construction area of coral reefs; regular monitoring of indicators of coral reefs swimming animals, plankton populations,nike jordan pas cher, the number, diversity; (7) construction and construction of ship-generated life and production waste water and solid waste are collected after the centralized and unified to the mainland harbor treatment; (8) years of working vessels are using the newer ship,jordan pas cher, to ensure that no oil spill incidents; regularly listen to weather forecasting and ocean forecasting, advance prepared to deal with typhoons and strong wave of defense preparations and other hydraulic structures engineering attacks,nike tn officiel, to avoid the loss of sand. In short,barbour soldes, take all response measures in the construction, ensure that the impact on coral reef ecosystems Dredging environment to a minimum. After construction is completed,abercrombie, it will carry out ecological compensation and rehabilitation measures reef communities. After years of painstaking research and practice, domestic and foreign scientists have tried a variety of coral reef ecosystem recovery methods designed artificial reef structure for a variety of coral reefs,hollister milano, it proved that as long as effective measures can be implemented to restore coral reef communities. The expansion project of the Nansha Islands coral ecosystem health impact assessment Chinese marine industry standard "near-shore marine ecosystem health assessment guidelines" (HY / T087-2005) into the coral reef ecosystem health.
