Abstract: To solve the problems exist in reservoirs of southen areas, such as long term short of fish feed, low fresh fish yield, serious soil erosion and large sinking of silts, experiments were conducted recently in Bai Pai Chong reservoir of Changsha county. The study aim at supplying feed for fish, conserving water and preventing soil erosion and sinking of silts in the reservoir by planting Lolium x hybridum Hausskn in the beach, Schunach, Coastcross 1 bermudagress and King grass in barren hills, and interplanting Dactylis glomerata L. and Trifolium repens L. with young trees. The results indicated that the annual output of fresh fish in the reservoir was increased from 1000kg to the current 7000~8000kg, and volume of silts was decreased by 5160 m3; and also significant economic and ecological effect were obtained in the study.

摘要: 为了解决我国南方山丘水库鱼饵奇缺、鲜鱼产量低及库区水土流失严重、泥沙淤积量大的难题.通过多年试验研究,结果表明,在库内消落区种植黑麦草,在荒山堤坝种植扁穗牛鞭草、岸杂一号狗牙根和皇草,在幼林行间种植鸡脚草、拉丁鲁白三叶等饲草配套养鱼,防止水土流失和防淤减积试验获得成功.鲜鱼产量由种草前1000kg提高到7000~8000kg,泥砂淤积量每年减少0.51万m3,经济、生态和社会效益显著.
