生物操纵理论与技术在富营养化湖泊治理中的应用

Advances on Biomanipulation in Control of Eutrophic Lakes

近年来,全球范围内湖泊富营养化问题日趋严重。以生物操纵理论为指导,采用水生食物网调控、改善水质、抑制藻类的生物修复方法,为解决这一问题提供了可行的途径。论文综述了生物操纵理论的产生、发展和应用,阐述了富营养化水体生态系统中肉食性鱼类、滤食性鱼类、浮游动物、沉水植物和细菌等的作用,并针对当前生物操纵技术应用中存在的差异性问题,提出了不同湖泊应根据其特性采取不同的组合技术并重点采取相应措施的建议。

The eutrophication situation of Lakes is very severe all over the world. Recently, a bioremediation technology (biomanipulation) was developed and hoped to solve the problem. Biomanipulation aimed to manipulating the food web to improve water quality and reduce algae, etc. The review introduced advances on biomanipulation in control of eutrophic lakes, and explained the function of piscivores, planktivore, zooplankton, submerged macrophyte and bacteria in eutrophic aquatic ecosystem. Aimed at great different results of biomanipulation applications at present, some suggestions were also put forward for the work of our country in this field , such as eutrophic lake must be dealt with a kind of measure and combinated techniques according to one's own characteristic, etc.
