【摘要】 为了解查干湖水质现状,于2009年4月与7月分别对查干湖进行了水质监测,分析了平水期与丰水期的水环境动态变化规律,并从自然因素与人为活动两方面进行了原因分析;同时利用单因子评价与级别功能评价法对查干湖进行了现状评价,认为查干湖在丰水期矿化度较高,确定主要污染因子是CODmn、TN和TP;最后提出要从灌区水资源有效利用(节水灌溉)、农田排水的出路问题及农田退水的资源化利用等方面来减少松原灌区盐碱地开发对查干湖可能造成的影响。更多还原

【Abstract】 In order to learn about the water quality of lake Chagan,the water quality were monitored in April and July 2009.We revealed the dynamic changes of the water environment in the normal and flood seasons,and analyzed the reasons from natural factors and human activities.By assessment of current situation of water quality in chagan lake with the single-factor assessment and level of function evaluation,we found out that the value of salinity is higher during the flood season and the major pollution factors are CODMn,TN and TP;Finally,we put forward corresponding suggestions to reduce the impacts of saline-alkali soil development in Chagan lake: ensuring effective utilization of water resources from irrigation;outlet of drainage;making use of the drainage as resources.更多还原
