摘  要:
百倍冲水库自1976年修建以来,养鱼由于饲料长期缺乏,300亩养鱼水面常年产鲜鱼1000kg左右,库内每年淤积泥砂0.6~0.8万立方米。作者于1985~1987年在库内的消落区种植黑麦草,紫云英;荒山种象草、扁穗牛鞭草;堤坝上种岸杂一号狗牙根;幼林地种鸡脚草、拉丁鲁白三叶等牧草配套养鱼和防止水土流失进行试验研究。结果,库内年鲜鱼产量由种草前1000kg提高到7000~8000kg,泥砂淤积量每年减少0.516万立方米,经济生态效益显著。

摘  要:
Since the establishment of Bai Pai Chong Reservoir in 1976, there was annually an output of only about 1000 kilograms of fresh fish due to short of fish feed, and up to 6000~8000 cubic metres of silt, Trials were conducted from 1985 through 1987 to plant Lolium X Hybridum Hausskn, Aeeraglous sinicus L. in the beach of the reservoir, Schumach and H. compressa in barren hills, Coastcross— 1 bermudagrass in dykes and dams, and to interplant Dacttglis glomerata L. and Ladino Trifolium repens L. With young trees as measures to supply fish feed and to prevent silt, The results showed that, annually,the output of fresh fish in the reservoir could consequently be increased to 7000 —8000 kilograms, and volume of silt could be reduced by 5160 cubic metres. Significant economic and ecological effects could also be achieved.
