【摘要】 对盘古河水产种质资源保护区进行现场调查,测定30项水质因子以及底泥和鱼体中13种金属元素,依据国家地表水二类标准,采用综合评价指数和有机污染评价公式评价其水质。结果表明,盘古河水产种质资源保护区的水质综合评价指数为0.27,有机污染综合评价指数为0 96,其水质优良,处于自然原始状态,为细鳞和江鳕等冷水性鱼类的生长、繁殖提供了良好条件。本文的调查和监测数据丰富了保护区的基础资料。更多还原

【Abstract】 The article takes it as its target to report its authors’investigation and physico-chemical monitoring and evaluation results of the water environment situation for lenok and burbot aquatic germplasm resources of Pangu River reserve, Heilongjiang, China. As is known, the natural reserve of Pangu River aquatic germplasm resources is one of the famous natural reserves for cold-water fish growing and breeding.Needless to say, it is of great significance to pursue its water-quality changing situations and protect its water quality from being polluted and contaminated through effective protection and observation.It is just for this goal that there is a great need for us to master the skills to test the physico-chemical properties of the river water.In this article, we have tested and analyzed over 30 indexes of the water and 13 metal elements existing in the sediments and fishes through on-site investigations.According to the second standard national surface water protection regulation, we have assessed the quality of the river water in accordance with the comprehensive evaluation indexes and the evaluation formula for the organic pollutants.The results of our investigation and analysis indicate that Pangu River, which is located in the north of Tahe County of Daxinganling area, with its geographic situations in the coordinates 52°09’-53°22’N, 123°19’-124°49’E.Our investigation and analysis results show that the water quality remains clean and clear, high and pure in the original state.The comprehensive evaluation indexes show that the water quality comprehensive evaluation index is 0.27 and the organic pollution comprehensive evaluation index is 0.96, which suggests that the water qualities are in full conformity with the state water protection standard level.The reach can provide us with a good condition for the growth and reproduction of cold-water fishes, such as lenok and burbot.更多还原
