摘要
2004年4月至2005年1月,对内蒙古自治区巴彦淖尔市农垦系统13个大中水面渔业资源进行了周年调查。文章对除乌梁素海以外其他12个中小湖泊调查结果进行总结分析。这些湖泊多数为草型浅水湖泊,盐碱含量较高,如纳林湖、姚军海子、白条海子总含盐量平均在3.5‰以上,个别水体如纳林湖、姚军海子总碱度平均超出15mol/l。大多水体有效氮含量较高,但有效磷不足,氮、磷比例失调。除大汉海子、刘铁海子和南一队海子的浮游生物含量较高外,其余9个湖泊浮游生物含量均较低,水质清瘦,鱼产量较低。并在调查基础上提出了综合开发利用渔业资源的建议。
From April 2004 to Jan.2005,we firstly investigated the fishier resoures of thirteen middle and small lakes including Wuliangsuhai lake of the farming system in Bayannur. Wuliangsuhai lake is the second lake in Inner Mongolia.In this article we analyzed and concluded the researching results of all lakes except Wuliangsuhai lake.The results indicated： most of lakes are the grass-type shallow water,that have higher salt and strong alkaline .Such as total salt is above 3.5%o in Nalin lake,Yaojun lake and Baitiao lake ,and total alkaline is over 15mol/L in Nalin lake and Yaojun lake .There are more virtual nitrogen hut less phosphor in most lakes.There is fewer plankton ,less fertilizer and lower output in 9 lakes except Dahan lake , Liutie lake and Nanyidu lake. From the above investigation we suggest that the exploitation and using of fishier resources should be extensive
