摘要
本文概述了1959年新安江建坝截流后,坝下形成长23km、面积9.9km^2、平均水深5.9m、平均水温10—17℃、流量378m^3/s的冷水区的水文、生物变动状况。对30年来该冷水区的渔业利用作了回顾的同时提出了进一步开发利用意见。
After the completion of the cut-off dam in 1959 in Xinanjiang river, a cold-water area has formed with 23km in length, 9.gkm^2 in area, 5.9m in average depth of the water, 10°—17°C in average water temperature and 378m^3/s in flow. This paper summarizes the condition of hydrology and biology of the cold-water area. It also looks back the utilization of the fishery for the past thirty years and. moreover, make a suggestion of further exploitation and utilization of it.
