輕度放牧
英文
undergrazing-
The results indicate that there is a strong to weak, then weak to strong evolution process for the total grassland desertification, middle desertification and slight desertification, which can be attributed to climate change and human activities, especially to the influence of climate change ; due to coal exploitation, the severe desertification is always distributing in " ? " around the mining land, and developing to the east quickly with the help of monsoon
結果表明：受氣候變化、超載放牧、掏挖藥材以及墾荒等因素的影響，輕度荒漠化、中度荒漠化以及荒漠化總面積存在由強轉弱、再由弱變強的演變過程：受煤炭開發的影響，重度荒漠化草地多圍繞礦業建設用地呈「 ? 」狀分佈，並且受季風影響向礦業建設用地東側發展迅速。Using the cluster analysis method and studying 16 sampling plots of shrub grassland where bothriochloa ischaemum is the dominant species, and the plots ' grass frequency, grass coverage, density, height, and biomass, we graded the plots into five grazing stages : light, proper, moderate, serious, and extreme
摘要在對放牧利用下的白羊草灌叢草地頻度、蓋度、密度、高度、生物量等數量特徵調查基礎上，運用系統聚類分析方法，可戒分為輕放、適牧、中牧、重牧和極牧五個階段。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
摘要根據近幾十年來放牧強度對綿羊放牧行為、採食植物組成和生產性能的影響進行了綜述，得出以下結論：綿羊的個體增重與放牧率之間呈線性負相關，而公頃增重與放牧率之間呈正相關；綿羊的採食量隨著放牧強度的加重而降低；放牧強度對母羊繁殖性能各指標影響差異不顯著；隨著放牧強度的加重，綿羊的採食時間增加，遊走、反芻臥息時間減少；每百口採食量和日採食量減少，而採食速度增加；放牧綿羊的嗜食性是相對的；輕牧有利於提高肉的品質，但是產肉量低，總的經濟效益不高。
