摘要
本调查研究于1984~1989年在甘肃张掖地区的肃南县和山丹县草地进行。研究得出,鸟类中的猛禽(隼形目、鸮形目)都是鼠类著名的天敌,在它们的食物中鼠类的遇见率高达75%,一般每个人工鹰架控制的有效草地面积为400亩。该试验地区共设立人工鹰架1561根,防治面积达50万亩,在生产上已获得了一定的经济效益。
The investigation and research on rangeland rat destruction was undertaken during 1984—1989 at Sunan and Shandan counties of Zhangye prefecture in Gausu province. The results clearly indicated that among birds, bird of prey(Falco cherrug and Buteo hemilasius)was key natural enemy of the rat. According to the investigation, rats took up more than 75% among the diet consumed by birds of prey. Ingeneral, rangeland rat damage with an area of 400mu could be effectively controlled by the application of one artificial hawk—attractive stand. There were 1561 hawk—attractive stands established so far in the experimental area, and as a consequence, 500, 000 mu of rangeland have been controlled with considerable economic returns.
