Hebei coastal waters polluted trends have not been effectively curbed
The reporter learned from the recently held provincial meeting on the marine environmental protection, coastal pollution is a serious problem in our province, showed declining trends in the marine environment, marine environmental degradation trends have not been effectively curbed.
coastal waters are seriously polluted. Monitoring data shows that in 2005 the waters of our province does not meet water quality standards for clean sea area of about 1176 square kilometers, of which the cleaner sea area of about 793 square kilometers, slightly polluted sea area of 175 square kilometers or moderately polluted area 111 square kilometers, serious polluted waters 97 square kilometers. Sediments of coastal waters are subject to different degrees of pollution, local pollutants contained in the waters increased, the body of shellfish contaminants is still high. Focus on the sewage outfall adjacent waters seriously polluted in the monitoring of the 31 sewage mouth, most of the sewage outfall into the sea there is the phenomenon of excessive emissions, most of the sea water emission targets do not meet water quality requirements of marine functional zones.
recession marine environment. As the marine pollution, overfishing and human engineering activities increased, showed varying degrees of marine living resources of recessionary trends. In 2004 found that 152 kinds of the intertidal zone than 1984 species have decreased by over 14 species, with an average biomass decreased by 71.4%, biological density decreased by 25.6%; found in 23 species of fish than in 1984, down 22 kinds of . Migratory fish spawning grounds and feeding grounds have been claims a certain degree of damage to a significant reduction in fish stocks and the economy appears smaller, young-oriented, the quality of aquatic products dropped, the commodity rate decrease was evident. Inshore marine ecosystems in the sub-healthy state, mainly in order to survive the loss of or change the environment, biological community structure anomaly.
marine disaster intensified. Because a large number of pollutants exceeding the excess into the sea, causing water eutrophication, in suitable weather conditions, the occurrence of red tide. In recent years, frequent red tides in our province, since 2001, red tides occurred 18 times, on the marine environment and aquaculture hazard. In recent years, less precipitation and rivers due to the construction of reservoirs upstream, resulting in Luan River and other major rivers into the sea runoff smaller, significantly reduced the amount of river sediment, coupled with an increase in the marine engineering activities and illegal sand mining have occurred from time, as well as coastal tourism with more than environmental capacity, leading to some serious coastal erosion, coastal segment. As part of the coastal shore drilling of underground water has led to lots of salt water intrusion, Qinhuangdao harbor area and lots of serious Funing County has reached 32 km length of seawater intrusion, invasion of an area of 300 square kilometers, resulting in salinization of groundwater quality, land salinization.
of crude oil pollution, land-based pollution damage incidents. Bohai Sea oil and natural gas-rich, with the degree of increased exploration, offshore oil development will further accelerate the number of ships at sea shipping has increased significantly, increasing the possibility of oil contamination. In addition, due to excessive concentration of land-based pollutants, over-into the sea, also caused damage to marine pollution incidents.
meeting called for the province’s marine environmental protection, coastal governments at all levels and relevant departments should further implement the scientific concept of development, follow the “prevention first, combining prevention with control, Hohai co-ordination, both land and sea, focused and integrated governance” the principle of strict control of pollutants in order to focus on the sea, to the comprehensive management of land and sea is crucial in order to restore and improve the marine environment as the goal to increase marine environmental protection efforts to further improve environmental quality.
河北沿海水域污染趋势没有得到有效遏制
记者从最近召开的关于海洋环境保护的省级会议上了解到,沿海污染是我省严重的问题,显示下降趋势,在海洋环境,海洋环境恶化的趋势没有得到有效遏制。
沿海水域受到严重污染。监测数据表明,2005年我省水域不符合约1176平方公里,海域清洁水质标准,其中约七九三平方公里清洁海域,稍175平方公里,中度污染海域污染面积111平方公里,严重九七平方公里受污染的水域。沿海水域沉积物受到不同程度的污染,当地水域中的污染物增加,贝类体内污染物仍然很高。对排污口附近海域严重的31排污口的监测污染的重点,对排污口入海最有过多排放的现象,海水排放指标大多不符合水质要求的海洋功能区。
衰退的海洋环境。由于海洋污染,过度捕捞和人类工程活动增加,显示不同程度的衰退趋势,海洋生物资源的程度。在2004年发现,一五二种潮间带物种比1984年超过14种减少与下跌71.4%,平均生物量,生物密度下降了25.6%;发现23种鱼类,比1984年下降了22种。洄游鱼类产卵场和觅食地一直声称的损害,在鱼类大量减少在一定程度和经济似乎更小,年轻为导向,对水产品质量下降,商品率下降明显。近岸海洋生态系统的分健康的状态,主要是为了生存的损失或改变环境,生物群落结构异常。
海洋灾害加剧。因为超过了入海污染物的大量过剩,造成水体富营养化,在适当的天气条件下,赤潮发生。近年来,赤潮频繁,我省自2001年以来,赤潮发生18次,对海洋环境和水产养殖的危害。近年来,降水量减少和河流由于建造水库上游,滦河和其他主要河流入海造成的径流小,大大减少了河流泥沙量与海洋工程中的活动和非法增加沙耦合,开采时有发生,以及超过环境容量多,导致一些严重的海岸侵蚀,沿海部分的滨海旅游业。作为沿海海岸地下水钻探部分,导致海水入侵,秦皇岛市海港区和抚宁县严重地段地段已达到32个海水入侵,对300平方公里的土地盐碱化的入侵,导致公里长地下水水质,土地盐碱化。
原油污染,土地
的污染损害事故。渤海石油和天然气丰富,随着勘探程度的增加,海洋石油开发将进一步加快在海上运输船舶数量明显增加,增加石油污染的可能性。此外,由于土地的过度集中的污染物,过大海,还造成破坏海洋污染事故。
全省的海洋环境保护会议要求,各级和各有关部门沿海政府要进一步贯彻落实科学发展观,遵循“预防为主,防治结合,河海统筹,陆地和海洋,重点突出综合治理“的原则,严格控制污染物,以便把重点放在海上,将土地和海洋综合管理是至关重要的,以恢复和改善海洋环境为目标,以提高海洋环境保护工作,以进一步改善环境质量。06.9.7
