Distribution of Dissolved Inorganic Carbon （DIC） and Its Related Parameters in Seawater of the North Yellow Sea and off the Qingdao Coast in October, 2007

Data on the distribution of dissolved inorganic carbon (DIC) were obtained from two cruises in the North Yellow Sea (NYS) and off the Qingdao Coast (QC) in October, 2007. Carbonate parameters were calculated. The concentrations of DIC are from 1.896–2.229 mmolL⁻¹ in the NYS and from 1.939–2.032 mmolL⁻¹ off the QC. In the southwest of the NYS, DIC in the upper layers decreases from the north of the SP (Shandong Peninsula) shelf to the center of the NYS; whereas in the lower layers DIC increases from the north of the SP shelf to the center of the NYS and South Yellow Sea. In the northeast of the NYS, DIC in all layers increases from the YR (Yalu River) estuary to the centre of the NYS. The distribution of DIC in NYS can be used as an indicator of Yellow Sea Cold Water Mass (YSCWM). Air-sea CO₂ fluxes were calculated using three models and the results suggest that both the NYS and the QC waters are potential sources of atmospheric CO₂ in October.     

减负5000亿元的政府答卷

温家宝总理3月5日在政府工作报告中提出,将采取减税、退税或免税高达5000亿元的方式减轻企业和居民税负,同时还将全面实施增值税转型,落实已出台的中小企业、房地产和证券交易相关税收优惠以及出口退税等方面政策.     

减负5000亿元的政府答卷

温家宝总理3月5日在政府工作报告中提出，将采取减税、退税或抵免税高达5000亿元的方式减轻企业和居民税负，同时还将全面实施增值税转型，落实已出台的中小企业、房地产和证券交易相关税收优惠以及出口退税等方面政策。这无疑可看作是给持续低迷的地产业、矿业的一份政策扶持答卷。
