陆水水库的浮游生物及营养类型

报道了１９９１￣１９９５年对面积为１６９３ｈｍ＾２的黑龙滩水库渔业利用优化模式研究的结果，主要内容有：水生生物种类组成和现存量调查、浮游植物初级生产力测定、渔获物统计和鱼产力估算；水体理化性状和水位变化对鱼产量和浮游生物群落结构的影响，网箱养殖鲤、草鱼的高产试验结果；多功能水库生态系统的渔业利用优化模式初步探讨。经三年努力，水库鱼产量由６２２ｔ上升到１２５５．１ｔ，平均单产７５０ｋｇ／ｈｍ＾２。为

The plankton and trophic state of Lushui Reservoir

Experiments in Comprehensive fishery exploitation were conducted in Hei Long Tan Reservoir (1693hm2) from 1991 to 1995. The major results are as follows: determination of aquatic biological productivity and fishery resources and estimation of maximum potential fish production, effect of water physi-chemical properties and water level change on fish yield and plankton community structure, intensive culture of carp, grass carps and bream in net-cages. and discussion of the comprehensive fishery exploitation of large-scale reservoirs of multiple function. As a result, the total fish yield of the reservoir has increaced from 622000kg to 1255 000kg, and the average fish yield gone up to 750kg/hm~2.
