Influence of fencing and light grazing on enclosed alpine steppes in the qinghai lake area 围栏内禁牧与轻牧对高寒草原群落的影响
As a case study , the responses of leymus chinensis steppe of songnen plain in northeast of china to human being activity ( light grazing , middle grazing , heavy grazing and overgrazing ) were discussed based on the field observed data 结果表明,随著放牧强度的增加,羊草草原的植被盖度和生物量随之降低,优势羊草群落将逐渐被盐生植物所替代,群落结构趋于简化,物种向旱生化和盐生化演替。
The paper summarized the research for the effects of different grazing intensity on grazing behaviour , grazing grass species and productivity of sheep in recent years , the result showed that : there was a negative correlation between the live weight gain per sheep and the grazing intensity , but there was positive correlation between the live weight gain per hectare and the grazing intensity ; feeding intake of sheep decreased when the grazing intensity become heavier ; there was not significant effect of different grazing intensity on sheep breeding indexes ; as long with the grazing intensity become heavier , the feeding time of sheep increased while resting and idling time decreased , but feeding intake per hundred mouths and daily intake reduced while intake velocity increased ; sheep feeding adaptability is relative ; the light grazing was beneficial to promote mutton quality , but mutton quantity and gross economy benefit was low 摘要根据近几十年来放牧强度对绵羊放牧行为、采食植物组成和生产性能的影响进行了综述,得出以下结论:绵羊的个体增重与放牧率之间呈线性负相关,而公顷增重与放牧率之间呈正相关;绵羊的采食量随著放牧强度的加重而降低;放牧强度对母羊繁殖性能各指标影响差异不显著;随著放牧强度的加重,绵羊的采食时间增加,游走、反刍卧息时间减少;每百口采食量和日采食量减少,而采食速度增加;放牧绵羊的嗜食性是相对的;轻牧有利于提高肉的品质,但是产肉量低,总的经济效益不高。
