非经典生物操纵修复富营养化的研究进展

Progress of Non-traditional Bio-manipulation in the Controlling of Eutrophication

采用非经典生物操纵技术防治水体富营养化,不仅投资少,并且有利于建立良性生态平衡。与经典的生物操纵相比,非经典生物操纵所依靠的放养对象,正好是经典生物操纵理论要求捕除或毒杀的对象,它主要是通过利用有特殊摄食特性、消化机制且群落结构稳定的滤食性鱼类来直接控制水华。

Non-traditional bio-manipulation technology for combating water eutrophication is the prevention method of environmental water pollution control with less investment and is conductive to establishing a healthy ecological balance. Compared with the traditional bio-manipulation, the stocking target of non-traditional bio-manipulation is exactly the requirement of traditional bio-manipulation in addition to arrest or kill, It is primarily through the use of filter-feeding fish which has special feeding characteristics, digestion mechanism and stability commanity structure to control the water bloom.
