我国淡水渔业中最重要的组成部分就是水库渔业。水库渔业的发展提高了人们生活水平、维护了水库的生态环境,带动了库区农民和部分水利职工的收入增长,促进了库区的经济发展。但由于某些因素的影响,水库渔业对水质产生了不利影响,对生态... 我国淡水渔业中最重要的组成部分就是水库渔业。水库渔业的发展提高了人们生活水平、维护了水库的生态环境,带动了库区农民和部分水利职工的收入增长,促进了库区的经济发展。但由于某些因素的影响,水库渔业对水质产生了不利影响,对生态平衡造成威胁,因此,本文针对水库渔业研究其对水质的影响,提出维护水库渔业生态平衡的对策。 展开更多

Huaihe River is one of three major rivers in China with a large population and developed economy. By the 1970s, the water quality of Huaihe River was deteriorating daily and more than a hundred serious pollution accidents of water quality happened and caused the inestimable losses in the production, life and health of residents along the river and terribly damaged the ecological system of the river. Through the continuous large-scale treatment for more than 10 years, the deterioration of water quality in Huaihe River has been basically inhibited. Nevertheless, the water pollution in Huaihe River is, on the whole, still very serious for many reasons, including special climatic conditions, terrible lack of water resource, obsolete industrial structure and unsound management system for the river, etc. This essay deeply analyzes the rea- sons why the water pollution of Huaihe River is "chronic" and puts forward the corresponding countermeasures for how to continuously improve the water quality of the river. In the end, this essay argues that it still takes 30-50 years or even a longer period, even if every measures are implemented smoothly and strictly, to actually make the water of Huaihe River clean and gradually restore its normal ecological and environmental functions. 展开更多
