生物操纵技术在西北地区水库水体富营养化防治应用前景

Study of Using Biomanipulation Technology to Control Eutrophication in Reservoirs in Northwest China

西北地区是我国最干旱的地区,水库在西北地区的工农业生产、渔业养殖、水利调度、防洪以及气候调节等方面发挥着极为重要的作用。外源污染的过量输入、来水量下降和补水不足、气温升高、生态系统受损是西北地区水库水体富营养化的成因。应对西北地区不同类型水库进行基础调查,了解水库水质状况和营养水平,有针对性的实施投放鱼食性鱼类或人工控制浮游动物食性鱼类、投放滤食性鱼类、投放螺、蚌、贝类等水生动物和人工调控水生植被等生物操纵技术。

The Northwest China is the driest area in China,and reservoirs play a very important role in industrial and agricultural production,fish farming,irrigation scheduling,climate regulation and flood control. Excessive input of extraneous sources of pollution,reservoir discharge decreased and shortage of water supply,temperature increased,and ecosystem damaged are the cause of water eutrophication of reservoirs in Northwest China. We should make investigation of different types of reservoirs in Northwest China ...
