中文摘要:
      本文通过对 1985年—1989年滆湖水质营养状态及此期间网围养殖规模和投饵情况调查结果的评价,分析了网围养殖对滆湖水体营养状态的影响。研究结果是:目前滆湖水质处于中营养(前期)状态。网围养殖后,加快了水体富营养化进程,但速度较同类浅水型湖泊缓慢。并根据对研究结果的分析提出了应采取的对策。
英文摘要:
      Lake Ge Hu, which is a shallow lake (average depth 1.25 meters)with a area of 137.82 square kilometers, locates in the southwest of Jiangsu Provin-ce. The lake is rich in submerged plants (over 86% is covered). Since 1984, therehas been developed pen fishculture in the lake, the yield of pen fishculture was upto 4664 tones in 1988. The evaluation of water trophic state, scale of development ofpen fishculture and feeding conditions in the lake mainly based on the surveys du-ring 1985--1989. The result indicates that the lake belongs to mesotrophic type(early). Although the eutrophication is progressing after yet, the process is stillslower than that in other similar shallow lakes. Accordingly,the proposation of samemeassures for lagging the lake eutrephication is based on the analysis.
