Study On The Enclosure Aquaculture And Its Influence On Water Environment In The Honghu Lake

In order to promote water environmental management,promote the harmony relationship between people and water,this article Study on the Enclosure Aquaculture and its Influence on Water Environment in the Honghu Lake.Through summarizing the enclosure aquaculture in Honghu Lake from experimental phase to expansion and then to vanishing,combined with the specific operation of the aquaculture and the living condition in the surrounding area,the influence of enclosure aquaculture to the environment of Honghu lake is analyzed in detail.The research mainly uses the statistical approach and inverse distance weighted method to analyze the influence of enclosure aquaculture on the changes of water quality.Also,analyze the influence of the fishery production on the environment of Honghu Lake.Through this research,it is considered that from the perspective of time,the rapid expansion of early purse seine culture has continuously reduced the free surface of lakes,increased the content of nitrogen and phosphorus in lake waters,aggravated the overall deterioration of lake water quality,accelerated the eutrophication process of lake waters.In the later period,the area of the fence was controlled and continuously reduced.The deterioration of water quality in Honghu Lake has been effectively controlled also.The water quality was improved,but the trend of eutrophication of water was not reversed.The enclosure aquaculture was mainly distributed in the shallow waters of the northeastern part of the lake and the western coast.The degree of eutrophication in those regions was slightly higher than that of other areas,mainly due tonitrogen and phosphorus produced by enclosure aquaculture that resulting in the eutrophication aggravation of lake water.After the demolition,the eutrophication,especially in the center lake area,which should be brought to the attention.In order to promote water environmental management,it is also necessary to reduce the breeding of lake banks(ponds)and control water pollution in the basin.From the perspective of community,the positive role of fishermen in lake governance and ecological protection should be recognized.We should develop ecological breeding and promote eco-friendly lifestyle.The mechanism of public participation in the lake protection should be introduced,which can promote the harmony relationship between people and water and can help to develop the sustainability of the Honghu lake area.
