rasshopper damage is one of the plagues that threat the grassland ecology system, which had adverse effects on the sustainable development of grassland and animal husbandry. It is special pressing to explore an economical, effective and secure technology that could keep grasshopper density under the economic threshold. An experiment on the effect of managing measures (grazing intensity, supplementing amount and grazing methods) on the grasshopper population quantity and chicken growth characteristics was conducted in alpine grassland in Qilian Mountains. The results indicated that foraging chickens could effectively regulate the grasshopper amount. Long-term and continuous chickens foraging could effectively suppress grasshopper population under the economic threshold. Different grazing intensity (15 chicken/hm² and 13 chicken/hm²) and supplementing amount did not affect significantly grasshopper amount, but have an obvious influence on the chicken growth. Both freely and limited time foraging can suppress grasshopper population, and the limited time foraging chicken had higher daily and finally body weight than those of freely foraging chicken. Combining the effect of controlling grasshopper and rearing chicken, 15 chicken per hectare at the frist grazing, limited time and appropriate supplement will gain the two-win goal in controlling grasshopper quantity and rearing chicken on rangeland.
